Dart2wasm only needs a platform file, which contains the compiled
`dart:*` libraries. There's no need to specify a seperate `--dart-sdk`
option (anymore).

This PR modifies the `flutter create --empty` command to not delete the `test/` folder when run on an existing app project.
Before:
```bash
flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test does not exist
```
After:
```bash
flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
```

This PR adds support invoking `link.dart` hooks.
Link hooks can add new assets. Link hooks can transform assets sent to link hook from build hooks.
This PR does not yet add support for getting tree-shake information in the link hooks. This is pending on defining the `resources.json` format (https://github.com/dart-lang/sdk/issues/55494).
Issue:
* https://github.com/flutter/flutter/issues/146263
## Implementation considerations
The build hooks could be run before Dart compilation and the link hooks after Dart compilation. (This is how it's done in Dart standalone.) However, due to the way the `Target`s are set up, this would require two targets and serializing and deserializing the `BuildResult` in between these. This would lead to more code but no benefits. Currently there is nothing that mandates running build hooks before Dart compilation.
## Testing
* The unit tests verify that the native_assets_builder `link` and `linkDryRun` would be invoked with help of the existing fake.
* The native assets integration test now also invokes an FFI call of a package that adds the asset during the link hook instead of the build hook.
* In order to keep coverage of the `flutter create --template=package_ffi`, `flutter create` is still run and the extra dependency is added and an extra ffi call is added. (Open to alternative suggestions.)
This PR adds a new flag `default-flavor` in the `flutter` section of `pubspec.yaml`. It allows developers of multi-flavor android apps to specify a default flavor to be used for `flutter run`, `flutter build` etc.
Using `flutter run` on flavored apps already works without specifying `--flavor` already works on iOS (it defaults to the `runner` schema), so I (and others in #22856) figured this would be nice to have.

This PR is step 12 in the journey to solve issue #136139 and make the
entire Flutter repo more readable.
Most of it involves implementing switch expressions, and there's also a
few other random things that I wanted to clean up a bit.
DDS was temporarily pinned to 4.1.0 because 4.2.0 triggered some test
failures (see https://github.com/flutter/flutter/pull/147250). Those
failures should be fixed by vm_service 14.2.2, so this unpins DDS and
rolls both of these packages (along with devtools_shared, which is a DDS
dependency).
(If the bot updates vm_service before this is done, I can rebase over
that will reduce the size of this PR to just a few files)
### Some background:
* Flutter registers the hot-restart service extension for all devices **except** web devices. For web devices, DWDS registers the service extensions.
* When a user is debugging their code via VS Code, the VS Code Dart extension [sends a hot-restart](94cb81c552/src/debug/run_daemon_base.ts (L100)) request via stdin/out to flutter_tools
* flutter_tools then [calls the "hotRestart" service extension](f3978c7a46/packages/flutter_tools/lib/src/isolated/resident_web_runner.dart (L447)) (which, again, has been registered by DWDS)
### Why is this change necessary?
In DWDS, we are changing how we register the "hotRestart" service extension (here is the PR for that: https://github.com/dart-lang/webdev/pull/2388). Previously, we registered the "hotRestart" service extension on a client that was directly connected to the VmService. With https://github.com/dart-lang/webdev/pull/2388, we will be registering the "hotRestart" service extension on a client that is connected to DDS.
When a service extension is registered against DDS, DDS adds a prefix to the service extension method name (e.g. "hotRestart" becomes "s0.hotRestart"). It informs clients of the service extension name via `kServiceRegistered` events sent to the `Service` stream.
Therefore, this change simply listens to those service extension registered events, and uses them to determine the "hotRestart" service extension's method name.

* Both of these don't test specific `Target`s, these have `TestTarget`s.
* test/integration.shard/isolated/native_assets_test.dart
* This could work, but it's an integration test that already takes long to run.

In service of https://github.com/flutter/flutter/issues/146879 and https://github.com/flutter/flutter/issues/145812. In these issues, we see what appears to be the flutter tool getting stuck somewhere during hot reload. It may help if we knew were exactly where we are getting stuck (preparing assets, writing them to device, etc.).
This PR adds a new parameter to `FlutterTestDriver::run`, `verbose`. When verbose is set, `FlutterTestDriver` will run `flutter` with `--verbose` in its tests. Keep in mind that `FlutterTestDriver` only prints logs from `flutter` when a test fails, so this shouldn't spam the logs of passing tests.
This PR sets the parameter when invoking the flaky tests from https://github.com/flutter/flutter/issues/146879 and #145812, so we should see more detailed logs in future flakes.
While this is a low risk PR, you can verify the change by intentionally breaking hot reload code, clearing the cached tool binaries, and then running either of these tests.
## Description
This introduces a list of packages that we will explicitly not pin. It is to be used for things where the package isn't actually published, but is a transitive dependency of another package included in the SDK. This happens with the `macros` package, for instance, which depends on the private, unpublished, `_macros` package where the SDK does some tricky things to depend on it (it depends on "any", but ships it as part of the SDK).
Also ran `flutter update-packages --force-update` to update all of the pubspec files.
## Related Issues
- Fixes#147656
## Tests
- Added a test that makes sure that explicitly unpinned packages don't show up in the pinned list.
- added language for all code blocks
- replaced `bash` or `shell` with `sh` for consistency.
- added `sh` and `console` in the GitHub template link generator.
- updated test for GitHub template.
Uses kernel concatenation to concatenate the `program.dill` and `native_assets.dill`.
This will enable compiling `native_assets.dill` after `program.dill` so that tree-shaking information can be used.
Issue:
* https://github.com/flutter/flutter/issues/146270
## Implementation choices
* We can either run the frontend_server twice as a process invocation (current PR), or keep the process running after the dart compilation and then shut it down after native assets compilation to kernel. Keeping the process running would require more coordination between different `Target`s.
* We can either chose to only do separate kernel file compilation in release (AOT) builds, or do it both for JIT and AOT (current PR). Doing it differently in JIT/AOT means more conditionals in lib/src/build_system/targets/, doing it single-shot in JIT might be more performant though.
Update: Both of these are mitigated by not running the kernel compiler process if there are no native assets at all.
## Implementation notes
This only updates `flutter assemble`.
The kernel compilation calls in `flutter run` do not require kernel concatenation. The native-assets-kernel-mapping in `flutter run` contains results from `--dry-run` invocations of `hook/build.dart` (and in the future `hook/link.dart`). These `--dry-run` invocations do not get access to tree-shaking information, so the `link` hook to be introduced later can be run before Dart compilation.
## Tests
* Updated the `Target`s tests to reflect the new implementation.

Here's another PR with a couple of typos fixed. As you can see there was a typo in _fileReferenceI**n**dentifiers_, in class _ParsedProjectInfo._ Maybe we should do some check on that since I'm not sure if that property is used somewhere outside Flutter?
From https://github.com/flutter/flutter/issues/143348#issuecomment-2016047148:
> before we ship, we should add a printTrace to the tool about each asset transformer we're invoking and the path/arguments we called it with
I think this is a good idea since asset transformers can be arbitrary Dart programsâmeaning that a lot can go wrong when running them. For example, they can hang indefinitely or perform some sort of I/O that later results in a tool crash. Knowing that asset transformation was involved when debugging a crash (or a slow/stuck `flutter build`) could be useful, so I think adding a `printTrace` or two is a good idea (or at least not a bad one).

This PR adds initial support for Swift Package Manager (SPM). Users must opt in. Only compatible with Xcode 15+.
Fixes https://github.com/flutter/flutter/issues/146369.
## Included Features
This PR includes the following features:
* Enabling SPM via config
`flutter config --enable-swift-package-manager`
* Disabling SPM via config (will disable for all projects)
`flutter config --no-enable-swift-package-manager`
* Disabling SPM via pubspec.yaml (will disable for the specific project)
```
flutter:
disable-swift-package-manager: true
```
* Migrating existing apps to add SPM integration if using a Flutter plugin with a Package.swift
* Generates a Swift Package (named `FlutterGeneratedPluginSwiftPackage`) that handles Flutter SPM-compatible plugin dependencies. Generated package is added to the Xcode project.
* Error parsing of common errors that may occur due to using CocoaPods and Swift Package Manager together
* Tool will print warnings when using all Swift Package plugins and encourage you to remove CocoaPods
This PR also converts `integration_test` and `integration_test_macos` plugins to be both Swift Packages and CocoaPod Pods.
## How it Works
The Flutter CLI will generate a Swift Package called `FlutterGeneratedPluginSwiftPackage`, which will have local dependencies on all Swift Package compatible Flutter plugins.
The `FlutterGeneratedPluginSwiftPackage` package will be added to the Xcode project via altering of the `project.pbxproj`.
In addition, a "Pre-action" script will be added via altering of the `Runner.xcscheme`. This script will invoke the flutter tool to copy the Flutter/FlutterMacOS framework to the `BUILT_PRODUCTS_DIR` directory before the build starts. This is needed because plugins need to be linked to the Flutter framework and fortunately Swift Package Manager automatically uses `BUILT_PRODUCTS_DIR` as a framework search path.
CocoaPods will continue to run and be used to support non-Swift Package compatible Flutter plugins.
## Not Included Features
It does not include the following (will be added in future PRs):
* Create plugin template
* Create app template
* Add-to-App integration
Changing the web renderer doesn't directly modify the environment's dart defines, and so doesn't do a full build invalidation. We need to include the web renderer in the build key for the compiler configuration. This information is used directly by the web targets to modify the dart defines that are passed into the compiler, so we need to rebuild if this information changes.
When performing artifact lookups for `Artifact.genSnapshot` for macOS desktop builds, a `TargetPlatform` is used to determine the name of the tool, typically `gen_snapshot_$TARGET_ARCH`. Formerly, this tool was always named `gen_snapshot`.
The astute reader may ask "but Chris, didn't we support TWO target architectures on iOS and therefore need TWO `gen_snapshot` binaries?" Yes, we did support both armv7 and arm64 target architectures on iOS. But no, we didn't initially have two `gen_snapshot` binaries. We did *build* two `gen_snapshots`:
* A 32-bit x86 binary that emitted armv7 AOT code
* A 64-bit x64 binary that emitted arm64 AOT code
At the time, the bitness of the `gen_snapshot` tool needed to match the bitness of the target architecture, and to avoid having to do a lot of work plumbing through suffixed `gen_snapshot` names, the author of that work (who, as evidenced by this patch, is still paying for his code crimes) elected to "cleverly" lipo the two together into a single multi-architecture macOS binary still named `gen_snapshot`. See: https://github.com/flutter/engine/pull/4948
This was later remediated over the course of several patches, including:
* https://github.com/flutter/engine/pull/10430
* https://github.com/flutter/engine/pull/22818
* https://github.com/flutter/flutter/pull/37445
However, there were still cases (notably `--local-engine` workflows in the tool) where we weren't computing the target platform and thus referenced the generic `gen_snapshot` tool.
See: https://github.com/flutter/flutter/issues/38933
Fixed in: https://github.com/flutter/engine/pull/28345
The test removed in this PR, which ensured that null `SnapshotType.platform` was supported was introduced in https://github.com/flutter/flutter/pull/11924 as a followup to https://github.com/flutter/flutter/pull/11820 when the snapshotting logic was originally extracted to the `GenSnapshot` class, and most invocations still passed a null target platform.
Since there are no longer any cases where `TargetPlatform` isn't passed when looking up `Artifact.genSnapshot`, we can safely make the platform non-nullable and remove the test.
This is pre-factoring towards the removal of the generic `gen_snapshot` artifact from the macOS host binaries (which are currently unused since we never pass a null `TargetPlatform`), which is pre-factoring towards the goal of building `gen_snapshot` binaries with an arm64 host architecture, and eliminate the need to use Rosetta during iOS and macOS Flutter builds.

This tweaks the Flutter doctor messages for CocoaPods.
This also switches the "unknown version" error to link to the update instructions instead of the installation instructions; the user has already installed CocoaPods in this scenario.

And will also be required for Swift Package Manager support https://github.com/flutter/flutter/pull/146256.
We could swap to "required" but macOS developers don't technically need to upgrade. We can let the Store itself enforce its policies. And we can swap to Xcode 15 "required" when SPM adoption is further along.

Part of #137040 and #80374
`possibleResolutions` and `possibleResolutions` used a key containing the platform and the plugin name via `getResolutionKey`. The global list is not necessary and also confusing. It can be avoided by handling the resolution of plugins per platform. This helps to have a more self-contained plugin resolution. This also is necessary to reuse the plugin resolution logic (per platform) for #137040.
This PR is to update material_color_utilities package version to the latest. `material_color_utilities/scheme/scheme_fruit_salad.dart` and `material_color_utilities/scheme/scheme_rainbow.dart` are exported after version 0.9.0.

This PR makes hot reloads reflect changes to transformer configurations under the `assets` section in pubspec.yaml.
This PR is optimized for ease of implementation, and should not be merged as-is. If it is merged as-is, seriously consider creating a tech debt issue and assigning it to someone to make sure it gets resolved.
There are two issues in the previous implementation:
1. `_populateDevices` will return the devices from `deviceNotifier` if it had been initialized, assuming that once it's initialized, it has been properly populated. That assumption is not true because calling getters like `onAdded` would initialize `deviceNotifier` without populating it.
2. `deviceNotifier` instance might be replaced in some cases, causing `onAdded` subscribers to lose any future updates.
To fix (1), this commit added the `isPopulated` field in `deviceNotifier` as a more accurate flag to determine if we need to populate it.
To fix (2), this commit made `deviceNotifier` a final member in `PolingDeviceDiscovery`.
* Adds support for `flutter test --wasm`.
* The test compilation flow is a bit different now, so that it supports compilers other than DDC. Specifically, when we run a set of unit tests, we generate a "switchboard" main function that imports each unit test and runs the main function for a specific one based off of a value set by the JS bootstrapping code. This way, there is one compile step and the same compile output is invoked for each unit test file.
* Also, removes all references to `dart:html` from flutter/flutter.
* Adds CI steps for running the framework unit tests with dart2wasm+skwasm
* These steps are marked as `bringup: true`, so we don't know what kind of failures they will result in. Any failures they have will not block the tree at all yet while we're still in `bringup: true`. Once this PR is merged, I plan on looking at any failures and either fixing them or disabling them so we can get these CI steps running on presubmit.

Pre work for https://github.com/flutter/engine/pull/51229. Removes a lot of code referencing v1 of the android embedding, though not necessarily all of it (I may have missed some, it is hard to know).

A ProxiedDevice has two port forwarder, one to forward remote host port and another to forward remote device port. During an attach workflow, the port was forwarded by the latter. Update ProxiedDDS to make sure that it works in such case.
This pull request is part of the effort to solve issue #144903.
In the past, my efforts to reduce line length involved refactoring away from switch statements, but unlike [yesterday's PR](https://github.com/flutter/flutter/pull/144905), this one is full of switch statements that make things more concise!
This makes several changes to flutter web app bootstrapping.
* The build now produces a `flutter_bootstrap.js` file.
* By default, this file does the basic streamlined startup of a flutter app with the service worker settings and no user configuration.
* The user can also put a `flutter_bootstrap.js` file in the `web` subdirectory in the project directory which can have whatever custom bootstrapping logic they'd like to write instead. This file is also templated, and can use any of the tokens that can be used with the `index.html` (with the exception of `{{flutter_bootstrap_js}}`, see below).
* Introduced a few new templating tokens for `index.html`:
* `{{flutter_js}}` => inlines the entirety of `flutter.js`
* `{{flutter_service_worker_version}}` => replaced directly by the service worker version. This can be used instead of the script that sets the `serviceWorkerVersion` local variable that we used to have by default.
* `{{flutter_bootstrap_js}}` => inlines the entirety of `flutter_bootstrap.js` (this token obviously doesn't apply to `flutter_bootstrap.js` itself).
* Changed `IndexHtml` to be called `WebTemplate` instead, since it is used for more than just the index.html now.
* We now emit warnings at build time for certain deprecated flows:
* Warn on the old service worker version pattern (i.e.`(const|var) serviceWorkerVersion = null`) and recommends using `{{flutter_service_worker_version}}` token instead
* Warn on use of `FlutterLoader.loadEntrypoint` and recommend using `FlutterLoader.load` instead
* Warn on manual loading of `flutter_service_worker.js`.
* The default `index.html` on `flutter create` now uses an async script tag with `flutter_bootstrap.js`.

We need to make sure that when source maps are enabled for the dart2js target, it advertises the sourcemap file as one of its outputs so that the web release bundle can copy it over.
The flutter engine & framework can opt out of this optimization for
individual classes / class hierarchies via:
* `@pragma(flutter:keep-to-string)`
* `@pragma(flutter:keep-to-string-in-subtypes)`
Or by using the convenience constant `@keepToString` from `dart:ui`.

The flag `throwOnPluginPubspecError` never actually was enabled during production in #79669, but only in some dart plugin tests. And in the tests the case of the error when enabling the flag was not explicitly tested. The only thing tested was, that it is not thrown when disabled.
As explained [here](https://github.com/flutter/flutter/pull/142035#discussion_r1484237904) the only case, where this error could be thrown is, when a dart implementation and a native inline implementation are provided simultaneously. But throwing an exception there is a wrong behavior, as both can coexist in a plugin package, thus in the pubspec file.
Disabling the flag means, that the error is not thrown and not shown to the user. This is the case in production (contrary to the dart plugin tests), which acts like these plugin cases of implementations are just skipped. And this is what actually should be done.
In conclusion, I think the case of coexisting dart and native implementation in pubspec was just overlooked and therefore this error validation was introduced, which is not necessary or even valid.

- This is tricky: I already added a test in #142035, which finally complies with the other tests, by removing the flag. So I think it falls in the category of "remove dead code".
- Theoretically this is a breaking change, as removing / altering some tests. But the flag actually was never valid or used, so IDK. But this may not does fall in the category of "contributed tests".

`DevFSBytesContent` (and it's descendant `DevFSStringContent`) have setters that change the underlying content. These are unused outside of tests, so this PR removes them. Amongst other things, this could help me refactor https://github.com/flutter/flutter/pull/144660 into something that has fewer pitfalls.
This is purely a refactoring.
We should always target the newest, and 34 is the newest. This isn't a requirement yet (like it is for 33+) but presumably it will be made required in the nearish future.

This enables asset transformation during hot reload (except for web, because that has its own implementation of `DevFS` ð). Asset transformers will be reapplied after changing any asset and performing a hot reload during `flutter run`.

Originally, my aim was just to refactor (as per usual), but while messing around with the `TableBorder.symmetric` constructor, I realized that `borderRadius` was missing!
This pull request makes a few class constructors more efficient, and it fixes#144277 by adding the missing parameter.

### Context:
DDC modules are abstractions over how libraries are loaded/updated. The entirety of google3 uses the DDC/legacy module system due to its flexibility extensibility over the other two (ES6 and AMD/RequireJS). Unifying DDC's module system saves us from duplicating work and will allow us to have finer grained control over how JS modules are loaded. This is a a prerequisite to features such as hot reload.
### Overview:
This change plumbs a boolean flag through flutter_tools that switches between DDC (new) and AMD (current) modules. This mode is automatically applied when `--extra-front-end-options=--dartdevc-module-format=ddc` is specified alongside `flutter run`. Other important additions include:
* Splitting Flutter artifacts between DDC and AMD modules
* Adding unit tests for the DDC module system
* Additional bootstrapper logic for the DDC module system
We don't expect to see any user-visible behavior or performance differences.
This is dependent on [incoming module system support in DWDS](https://github.com/dart-lang/webdev/pull/2295) and [additional artifacts in the engine](https://github.com/flutter/engine/pull/47783).
This is part of a greater effort to deprecate the AMD module system: https://github.com/dart-lang/sdk/issues/52361
This pull request fixes#143803 by taking advantage of Dart's null-aware operators.
And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.
This PR implements the functionality described above and hides it behind
the `--experimental-faster-testing` flag of `flutter test`.

fixes#140656
* Flags to `dart compile wasm`
Some options are not relevant to a standalone user of `dart compile
wasm` (e.g. specyfing dart-sdk, platform file etc). => Those aren't
offered by the `dart compile wasm` tool directly. => We use the
`--extra-compiler-option=` instead which passes through arbitrary
options to the dart2wasm compiler. => We don't maintain compatibility of
those options, if we update them we'll ensure to also update flutter
tools
* Binaryen optimization passes
This change will mean we use the binaryen flags from Dart SDK which are
slightly different from the ones in flutter.
* Optimization configuration
This change will also start using the more standardized `-O` flag for
determining optimization levels. The meaning of those flags have been
mostly aligned with dart2js (with some differences remaining).
* Minimization
Using the new optimization flags, namely `-O4` for `--wasm-opt=full`,
will automatically enable the new `--minify` support. Minification is
Dart semantics preserving but changes the `<obj>.runtimeType.toString()`
to use minified names (just as in dart2js).
* Code size changes
Overall this change will reduce wonderous code size by around 10%.
Issue https://github.com/dart-lang/sdk/issues/54675
In service of https://github.com/flutter/flutter/issues/143348.
**Issue.** The `equals` implementation of `AssetsEntry` is incorrect. It compares `flavors` lists using reference equality. This PR addresses this.
This also adds a test to make sure valid asset `flavors` declarations are parsed correctly.
While we are here, this PR also includes a couple of refactorings:
* `flutter_manifest_test.dart` is a bit large. To better match our style guide, I've factored out some related tests into their own file.
* A couple of changes to the `_validateListType` function in `flutter_manifest.dart`:
* The function now returns a list of errors instead of accepting a list to append onto. This is more readable and also allows callers to know which errors were found by the call.
* The function is renamed to `_validateList` and now accepts an `Object?` instead of an `YamlList`. If the argument is null, an appropriate error message is contained in the output. This saves callers that are only interested in validation from having to write their own null-check, which they all did before.
* Some error strings were tweaked for increased readability and/or grammatical correctness.
This is an attempt at a reland of https://github.com/flutter/flutter/pull/141396
The main changes here that are different than the original PR is fixes to wire up the `flutter test` command properly with the web renderer.
This is in service of https://github.com/flutter/flutter/pull/141194
This will make it easier to get the `flutter run -d <browser>` and `flutter build fuschia` cases easier to get under test.
This is a direct revert of (the revert of (the reland of (the policy pr))): https://github.com/flutter/flutter/pull/143132.
The only change is:
1. to put a conditional all on one line, because the packages repository has a test that uses an old flutter project to make sure nothing regresses. The old project uses an old gradle version, and the old gradle version bundles an old groovy version, and the old groovy version has a bug where lines that start with `&&` don't always work: https://issues.apache.org/jira/browse/GROOVY-7218 (I enjoy that the revert reason ends up providing another strong justification to go forward with the policy). Also thanks to @reidbaker for pointing out this bug.
2. I also made a slight formatting change to the messages that print when out of the support bounds, which I think looks slightly better.
I tested this with on a branch that included a revert of https://github.com/flutter/flutter/pull/142008, and was able to recreate the failure and verify that it was resolved by 1).
Re land of https://github.com/flutter/flutter/pull/142000.
Differences:
1. Fixed the test that was failing in postsubmit. The reason was that the Flutter Gradle Plugin was being applied after KGP in that test, so we couldn't find the KGP version. This caused a log, and the test expects no logs. I moved FGP to after KGP
2. Added to the logs for when we can't find AGP. Change is from
> "Warning: unable to detect project AGP version. Skipping version checking."
to
> ~"Warning: unable to detect project AGP version. Skipping version checking. \nThis may be because you have applied the Flutter Gradle Plugin after AGP."~
update: the above is wrong, changed to
> "Warning: unable to detect project KGP version. Skipping version checking. \nThis may be because you have applied AGP after the Flutter Gradle Plugin."
3. Added a note to the app-level build.gradle templates that FGP must go last
> // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugin.
Dual Web Compile has had some issues where `flutter test` is not respecting the `--web-renderer` flag for some reason. I haven't gotten entirely to the bottom of the issue, but for now we need to rever these changes while I investigate. This reverts the following PRs:

The move of the fakes for packages/flutter_tools/test/general.shard/resident_runner_test.dart was erroneous before, as it was trying to use setters instead of a private field. This PR changes the private `_devFS` field in the fake to be a public `fakeDevFS` in line with other fakes.
## Original PR description
Native assets in other build systems are not built with `package:native_assets_builder` invoking `build.dart` scripts. Instead all packages have their own blaze rules. Therefore we'd like to not depend on `package:native_assets_builder` from flutter tools in g3 at all.
This PR aims to move the imports of `native_assets_builder` and `native_assets_cli` into the `isolated/` directory and into the files with a `main` function that are not used in with other build systems.
In order to be able to remove all imports in files used by other build systems, two new interfaces are added `HotRunnerNativeAssetsBuilder` and `TestCompilerNativeAssetsBuilder`. New parameters are then piped all the way through from the entry points:
* bin/fuchsia_tester.dart
* lib/executable.dart
The build_system/targets dir is already excluded in other build systems.
So, after this PR only the two above files and build_system/targets import from `isolated/native_assets/` and only `isolated/native_assets/` import `package:native_assets_cli` and `package:native_assets_builder`.

~Still a WIP while I clean up some error handling, remove some prints, and figure out a Java test (more difficult than the others because I believe we can only install one java version per ci shard).~
~Also it looks like there are errors that I need to fix when this checking is applied to a project that uses the old way of applying AGP/KGP using the top-level `build.gradle` file (instead of the new template way of applying them in the `settings.gradle` file).~ Done, this is why [these lines exist](9af6bae6b9/packages/flutter_tools/gradle/src/main/groovy/flutter.groovy (L72-L88)) in `flutter.groovy`. They just needed to be added
Since `WebReleaseBundle` is responsible for copying over the outputs from the subtargets, so it needs to be reflected in inputs and outputs so that things will be recopied when something changes.

Add a new `BuildTargets` class that provides commonly used build targets. And avoid importing files from `build_system/targets` except from the top level entrypoints or from top level commands.
Also move `scene_importer.dart` and `shader_compiler.dart` into `build_system/tools` because they are not `Target` classes, but wrapper for certain tools.
With this change, we can ignore all files in `build_system/targets` internally and make PR #142709 easier to land internally. See cl/603434066 for the corresponding internal change.

Also note that I have opted to add a new variable in `globals.dart` for `BuildTargets` in this PR, but I know that we are trying to get rid of globals. Several alternatives that I was considering:
1. Add a new field in `BuildSystem` that returns a `BuildTargets` instance. Since `BuildSystem` is already in `globals`, we can access build targets using `globals.buildSystem.buildTargets` without adding a new global variable.
2. Properly inject the `BuildTargetsImpl` instance from the top level `executable.dart` and top level commands.
Let me know if you want me to do one of the above instead. Thanks!
This implements dual compile via the newly available flutter.js bootstrapping APIs for intelligent build fallback.
* Users can now use the `FlutterLoader.load` API from flutter.js
* Flutter tool injects build info into the `index.html` of the user so that the bootstrapper knows which build variants are available to bootstrap
* The semantics of the `--wasm` flag for `flutter build web` have changed:
- Instead of producing a separate `build/web_wasm` directory, the output goes to the `build/web` directory like a normal web build
- Produces a dual build that contains two build variants: dart2wasm+skwasm and dart2js+CanvasKit. The dart2wasm+skwasm will only work on Chrome in a cross-origin isolated context, all other environments will fall back to dart2js+CanvasKit.
- `--wasm` and `--web-renderer` are now mutually exclusive. Since there are multiple build variants with `--wasm`, the web renderer cannot be expressed via a single command-line flag. For now, we are hard coding what build variants are produced with the `--wasm` flag, but I plan on making this more customizable in the future.
* Build targets now can optionally provide a "build key" which can uniquely identify any specific parameterization of that build target. This way, the build target can invalidate itself by changing its build key. This works a bit better than just stuffing everything into the environment defines because (a) it doesn't invalidate the entire build, just the targets which are affected and (b) settings for multiple build variants don't translate well to the flat map of environment defines.
When the Dart VM is not found within 10 minutes in CI on CoreDevices (iOS 17+), stop the app and upload the logs from DerivedData. The app has to be stopped first since the logs are not put in DerivedData until it's stopped.
Also, rearranged some logic to have CoreDevice have its own function for Dart VM url discovery.
Debugging for https://github.com/flutter/flutter/issues/142448.
Refactors `ShaderTarget` to make it opaque as to whether it's using Impeller or SkSL and instead has it focus on the target platform it's generating for.
ImpellerC includes SkSL right now whether you ask for it or not.
The tester target also might need SkSL or Vulkan depending on whether `--enable-impeller` is passed.
This PR increases Android's `minSdkVersion` to 21.
There are two changes in this PR aside from simply increasing the number
from 19 to 21 everywhere.
First, tests using `flutter_gallery` fail without updating the
lockfiles. The changes in the PR are the results of running
`dev/tools/bin/generate_gradle_lockfiles.dart` on that app.
Second, from
[here](https://developer.android.com/build/multidex#mdex-pre-l):
> if your minSdkVersion is 21 or higher, multidex is enabled by default
and you don't need the multidex library.
As a result, the `multidex` option everywhere is obsolete. This PR
removes all logic and tests related to that option that I could find.
`Google testing` and `customer_tests` pass on this PR, so it seems like
this won't be too breaking if it is at all. If needed I'll give this
some time to bake in the framework before landing the flutter/engine
PRs.

It's now possible to natively compile a flutter app for windows-arm64. Cross-compilation is not yet implemented.
Uses arm64 artifacts now available for Dart/Flutter. Platform detection is based on Abi class, provided by Dart. Depending if Dart is an arm64 or x64 binary, the Abi is set accordingly. Initial bootstrap of dart artifacts (update_dart_sdk.ps1) is checking PROCESSOR_ARCHITECTURE environment variable, which is the way to detect host architecture on Windows.
This is available only for master channel (on other channels, it fallbacks to windows-x64).
On windows-x64, it produces an x64 app. On windows-arm64, it produces an arm64 app.
The legacy welcome message would be printed even if `CI=true` confusing
parsers of the output.

Part of work on https://github.com/flutter/flutter/pull/141194
The [`AssetBundle`](0833929c99/packages/flutter_tools/lib/src/asset.dart (L80)) class contains two members, `entries` and `entryKinds`. `entries` contains asset data indexed by asset key. `entryKinds` contains the "kinds" of these assets, again indexed by asset key.
**Change.** Rather than have two separate maps, this PR proposes combining these maps into one by wrapping the asset data and kind into a single data type `AssetBundleEntry`.
**Purpose.** In https://github.com/flutter/flutter/pull/141194, I am considering associating more information with an asset. In particular, what transformers are meant to be applied to it when copying it to the build output. Rather than adding another map member onto `AssetBundle` (e.g. `entryTransformers`), I decided to make things neater by introducing the `AssetBundleEntry` type.

Rolls the packages from https://github.com/dart-lang/native in the native assets implementation.
Most notable we're refactoring `package:native_assets_cli` for `build.dart` use.
Therefore, all imports to that package for Flutter/Dart should be to the implementation internals that are no longer visible for `build.dart` writers. Hence all the import updates.
No behavior in Flutter apps should change.
This PR also updates the template to use the latests version of `package:native_assets_cli` which no longer exposes all the implementation details.
Packages the native assets for iOS and MacOS in frameworks.

## Details
* [x] This packages dylibs from the native assets feature in frameworks. It packages every dylib in a separate framework.
* [x] The dylib name is updated to use `@rpath` instead of `@executable_path`.
* [x] The dylibs for flutter-tester are no longer modified to change the install name. (Previously it was wrongly updating the install name to the location the dylib would have once deployed in an app.)
* [x] Use symlinking on MacOS.

## Implementation details for Android add2app
The `.so` files are bundled with the same mechanism that bundles `libapp.so`.
Change the following in the `flutter create` templates. I didn't make any auto-migrations for existing apps because none seem that critical:
1. Turn on `ASSETCATALOG_COMPILER_GENERATE_SWIFT_ASSET_SYMBOL_EXTENSIONS` in iOS and macOS.
1. Turn on `BuildIndependentTargetsInParallel` in macOS template. https://github.com/flutter/flutter/pull/125827/files#r1181817619
1. Turn on `DEAD_CODE_STRIPPING` in macOS template.
1. Set `ENABLE_USER_SCRIPT_SANDBOXING=NO` in iOS and macOS template. `flutter` scripts don't work with this on. This might require a migration in the future to explicitly turn this one off. However at least for now if the setting isn't present it defaults to `NO`.
Add migration for `LastUpgradeVersion` so users won't see these validation issues in Xcode.
Run migrator on all the example apps. A few aren't Flutter apps so I edited them in Xcode.

This updates the `Analytics` constructor to provide it with the enabled features for the flutter-tool. This will be sent with each event for the flutter-tool.
List of changes:
1. Optimizations in FileTransfer. a. Use `stream.forEach` instead of `await for`. b. Type cast `List<int>` to `Uint8List` instead of using `Uint8List.fromList` results in (presumably) fewer copy and faster execution. c. Iterate through `Uint8List` with regular for loop instead of for-in loop.
2. Precache the block hashes of a file, and reuse it on subsequent runs.

This adds a static helper method `ProcessUtils.writelnToStdinGuarded()`, which will asynchronously write to a sub-process's STDIN `IOSink` and catch errors.
In talking with Brian, it sounds like this is the best and most reliable way to catch `SocketException`s during these writes *to sub-process file descriptors* specifically (with a "real" hard drive file, the future returned by `.flush()` should complete with the write error).
Also, as I note in the dartdoc to `writelnToStdinGuarded()`, the behavior seems to be different between macOS and linux.
Moving forward, in any place where we want to catch exceptions writing to STDIN, we will want to use this new helper.
For CoreDevices we use a combination of mDNS and device logs to find the Dart VM url. If mDNS fails first, it will cause the launch to fail even though the device logs may be able to find the url. So if one of the methods fails, wait for the other method before failing the launch.

Original Description:
Provides support for conditional bundling of assets through the existing `--flavor` option for `flutter build` and `flutter run`. Closes https://github.com/flutter/flutter/issues/21682. Resolves https://github.com/flutter/flutter/issues/136092
## Change
Within the `assets` section pubspec.yaml, the user can now specify one or more `flavors` that an asset belongs to. Consider this example:
```yaml
# pubspec.yaml
flutter:
assets:
- assets/normal-asset.png
- path: assets/vanilla/ice-cream.png
flavors:
- vanilla
- path: assets/strawberry/ice-cream.png
flavors:
- strawberry
```
With this pubspec,
* `flutter run --flavor vanilla` will not include `assets/strawberry/ice-cream.png` in the build output.
* `flutter run --flavor strawberry` will not include `assets/vanilla/ice-cream.png`.
* `flutter run` will only include `assets/normal-asset.png`.
## Open questions
* Should this be supported for all platforms, or should this change be limited to ones with documented `--flavor` support (Android, iOS, and (implicitly) MacOS)? This PR currently only enables this feature for officially supported platforms.
## Design thoughts, what this PR does not do, etc.
### This does not provide an automatic mapping/resolution of asset keys/paths to others based on flavor at runtime.
The implementation in this PR represents a simplest approach. Notably, it does not give Flutter the ability to dynamically choose an asset based on flavor using a single asset key. For example, one can't use `Image.asset('config.json')` to dynamically choose between different "flavors" of `config.json` (such as `dev-flavor/config.json` or `prod-flavor/config.json`). However, a user could always implement such a mechanism in their project or in a library by examining the flavor at runtime.
### When multiple entries affect the same file and 1) at least one of these entries have a `flavors` list provided and 2) these lists are not equivalent, we always consider the manifest to be ambiguous and will throw a `ToolExit`.
<details>
For example, these manifests would all be considered ambiguous:
```yaml
assets:
- assets/
- path: assets/vanilla.png
flavors:
- vanilla
assets:
- path: assets/vanilla/
flavors:
- vanilla
- path: assets/vanilla/cherry.png
flavor:
- cherry
# Thinking towards the future where we might add glob/regex support and more conditions other than flavor:
assets:
- path: assets/vanilla/**
flavors:
- vanilla
- path: assets/**/ios/**
platforms:
- ios
# Ambiguous in the case of assets like "assets/vanilla/ios/icon.svg" since we
# don't know if flavor `vanilla` and platform `ios` should be combined using or-logic or and-logic.
```

### This does not support Android's multidimensional flavors feature (in an intuitive way)
<details>
Conder this excerpt from a Flutter project's android/app/build.gradle file:
```groovy
android {
// ...
flavorDimensions "mode", "api"
productFlavors {
free {
dimension "mode"
applicationIdSuffix ".free"
}
premium {
dimension "mode"
applicationIdSuffix ".premium"
}
minApi23 {
dimension "api"
versionNameSuffix "-minApi23"
}
minApi21 {
dimension "api"
versionNameSuffix "-minApi21"
}
}
}
```
In this setup, the following values are valid `--flavor` are valid `freeMinApi21`, `freeMinApi23`, `premiumMinApi21`, and `premiumMinApi23`. We call these values "flavor combinations". Consider the following from the Android documentation[^1]:
> In addition to the source set directories you can create for each individual product flavor and build variant, you can also create source set directories for each combination of product flavors. For example, you can create and add Java sources to the src/demoMinApi24/java/ directory, and Gradle uses those sources only when building a variant that combines those two product flavors.
>
> Source sets you create for product flavor combinations have a higher priority than source sets that belong to each individual product flavor. To learn more about source sets and how Gradle merges resources, read the section about how to [create source sets](https://developer.android.com/build/build-variants#sourcesets).
This feature will not behave in this way. If a user utilizes this feature and also Android's multidimensional flavors feature, they will have to list out all flavor combinations that contain the flavor they want to limit an asset to:
```yaml
assets:
- assets/free/
flavors:
- freeMinApi21
- freeMinApi23
```
This is mostly due to a technical limitation in the hot-reload feature of `flutter run`. During a hot reload, the tool will try to update the asset bundle on the device, but the tool does not know the flavors contained within the flavor combination (that the user passes to `--flavor`). Gradle is the source of truth of what flavors were involved in the build, and `flutter run` currently does not access to that information since it's an implementation detail of the build process. We could bubble up this information, but it would require a nontrivial amount of engineering work, and it's unclear how desired this functionality is. It might not be worth implementing.

Updates Gradle version for Flutter project templates and integration tests to at least 7.6.3 (changed all of those with versions below it) to fix security vulnerability.
Part of fix for https://github.com/flutter/flutter/issues/138336.
Support for FFI calls with `@Native external` functions through Native assets on Android. This enables bundling native code without any build-system boilerplate code.
For more info see:
* https://github.com/flutter/flutter/issues/129757
### Implementation details for Android.
Mainly follows the design of the previous PRs.
For Android, we detect the compilers inside the NDK inside SDK.
And bundling of the assets is done by the flutter.groovy file.
The `minSdkVersion` is propagated from the flutter.groovy file as well.
The NDK is not part of `flutter doctor`, and users can omit it if no native assets have to be build.
However, if any native assets must be built, flutter throws a tool exit if the NDK is not installed.
Add 2 app is not part of this PR yet, instead `flutter build aar` will tool exit if there are any native assets.
## Summary
Fixes https://github.com/flutter/flutter/issues/139180, where `flutter create` could crash if the `java` binary the tool found cannot be run.
## Context
At startup, the tool searches for a Java installation[^1]. Unless the located installation is from [an Android Studio installation](e1967ecabf/packages/flutter_tools/lib/src/android/android_studio.dart (L163)), the tool does not verify that the binary is runnable. For more, see https://github.com/flutter/flutter/issues/139613, which tracks this inconsistency in behavior.
This means that in the scenario where
1) the user does not have Android Studio installed or the java binary found within cannot be run **and**
2) the user has a) `flutter config --jdk-dir` set, b) `JAVA_HOME` set in their environment, **or** c) `java` on their system path **and**
3) the java binary we think we found during cannot be run (or `java --version` fails), **then**
the user running `flutter create` with Android enabled will hit a tool crash.
## Change
`Java.version` should return null if version checking fails for any reason. [This is documented behavior](48f57621ad/packages/flutter_tools/lib/src/android/java.dart (L136)). Therefore, we'll update the implementation to first verify that the binary is runnable. If it isn't, it will return `null`.
[^1]: We find java by calling the static `Java.find`, see: 48187028c1/packages/flutter_tools/lib/src/context_runner.dart (L271)
[^2]: This PR doesn't change this, as this would be too dangerous to cherry-pick into stable.

Checks `pod install` output for the case where a pod requires a higher minimum OS deployment target version than the app is set to use, and attempts to turn it into a more actionable error message. This isn't foolproof since we are parsing the Ruby rather than actually executing it, but I would expect that the vast majority of cases would end up in the most useful version (and even those that don't are still much clearer with this as the final error message text than without it).

Without this, if a user runs an app that has plugins that call method channels with the `preview` device, the app will build successfully, however, they will get a runtime error when their dart code tries to call the method channel that does not exist in the native build (which was pre-built and thus does not include the plugin code).
This change adds a validation when injecting plugins that will tool exit if the device-id is `preview` and their project contains plugins with method channels.

Fixes https://github.com/flutter/flutter/issues/130808. Short context is that the migration guide doesn't help when a user has a newer java version than 17, and this tells them how to fix the error in that situation.
This is an alternative to https://github.com/flutter/flutter/pull/131354, because I think it is a bad idea to introduce branching in how we handle this error with some specialized regexp.
Analyzer's dependency on autosnapshotting causes issues.
Because every version of integration_test from sdk depends on leak_tracker from hosted and autosnapshotting depends on leak_tracker from path, integration_test from sdk is forbidden.
So, because autosnapshotting depends on integration_test from sdk, version solving failed.

package:coverage has been rolled, so the breakages should be fixed.

## Description
This PR adds a `nonce` parameter to flutter.js' `loadEntrypoint` method.
When set, loadEntrypoint will add a `nonce` attribute to the `main.dart.js` script tag, which allows Flutter to run in environments slightly more restricted by CSP; those that don't add `'self'` as a valid source for `script-src`.
----
### CSP directive
After this change, the CSP directive for a Flutter Web index.html can be:
```
script-src 'nonce-YOUR_NONCE_VALUE' 'wasm-unsafe-eval';
font-src https://fonts.gstatic.com;
style-src 'nonce-YOUR_NONCE_VALUE';
```
When CSP is set via a `meta` tag (like in the test accompanying this change), and to use a service worker, the CSP needs an additional directive: [`worker-src 'self';`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/worker-src)
When CSP set via response headers, the CSP that applies to `flutter_service_worker.js` is determined by its response headers. See **Web Workers API > [Content security policy](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers#content_security_policy)** in MDN.)
----
### Initialization
If the CSP is set to disallow `script-src 'self'`, a nonce needs to also be passed to `loadEntrypoint`:
```javascript
_flutter.loader.loadEntrypoint({
nonce: 'SOME_NONCE',
onEntrypointLoaded: (engineInitializer) async {
const appRunner = await engineInitializer.initializeEngine({
nonce: 'SOME_NONCE',
});
appRunner.runApp();
},

(`nonce` shows twice for now, because the entrypoint loader script doesn't have direct access to the `initializeEngine` call.)

Fixes https://github.com/flutter/flutter/issues/136698.
Alters how `throwToolExit` creates its matcher. This results is an improved description of the matcher.
The mismatch description isn't improved by this, but I writing an entirely custom matcher to fix this isn't ideal either. We can instead mitigate the issue by augmenting the `toString` implementation of `ToolExit` to include the exit code, if it is non-null.
With these changes, the first few lines of output from a test would look like this:
```
Expected: throws <Instance of 'ToolExit'> with `exitCode`: <42> and `message`: contains 'message'
Actual: <Closure: () => Never>
Which: threw ToolExit:<Exit code: 41232. Error: message>
```

Extracts out _shouldWriteCodeSizeAnalysis and _writeCodeSizeAnalysis from the main buildMacOS function.
No tets changes sine this is a simple restructuring for readability and does not change any tool logic.

Original Description:
One of the reasons gathering coverage information is expensive is that we have to force compile every function in the libraries we're interested in. Without this, functions that haven't been invoked (so haven't been compiled) won't have any line number information, so the coverage tool doesn't know which lines to add to the list of misses. In flutter's case, the test infra spawns many VMs, and each of these needs to recompile all those libraries.
To fix this, we need a way of skipping force compilation for libraries we've already seen in previous tests, without losing the information about which lines in each library are coverable. So I [added](https://github.com/dart-lang/coverage/pull/466) the `coverableLineCache` to `coverage.collect` in package:coverage v1.7.0. This cache starts out empty, but fills up with lists of all the lines that are coverable for every library as coverage is gathered. package:coverage can then tell the VM not to force compile any libraries in this cache (using `getSourceReport`'s `librariesAlreadyCompiled` param). So the first test suite will still have to compile everything, but subsequent test suites will be much faster.
This speeds up coverage collection significantly, for large test suites:
| Running flutter/packages/flutter tests... | Time | Overhead |
| --- | --- | --- |
| without coverage | 8:53 | - |
| with coverage | 20:25 | 130% |
| with `coverableLineCache` | 12:21 | 40% |
