After this PR, `<Plugin>.isDevDependency` is resolved based on the following logic, IFF:
- The plugin comes from a package _A_ listed in the app's package's `dev_dependencies: ...`
- The package _A_ is not a normal dependency of any transitive non-dev dependency of the app
See [`compute_dev_dependencies_test.dart`](51676093a3/packages/flutter_tools/test/general.shard/compute_dev_dependencies_test.dart) for probably the best specification of this behavior.
We (still) do not write the property to disk (i.e. it never makes it to `.flutter-plugins-dependencies`), so there is no impact to build artifacts at this time; that would come in a follow-up PR (and then follow-up follow-up PRs for the various build systems in both Gradle and Xcode to actually use that value to omit dependencies).
Some tests had to be updated; for the most part it was updating the default `ProcessManager` because a call to `dart pub deps --json` is now made in code that computes what plugins are available, but there should be no change in behavior.
_/cc @jonasfj @sigurdm for FYI only (we talked on an internal thread about this; see https://github.com/dart-lang/sdk/issues/56968)._

Work towards https://github.com/flutter/flutter/issues/157819. **No behavior changes as a result of this PR**.
Based on a proof of concept by @jonahwilliams (https://github.com/flutter/flutter/pull/157818).
The existence of this flag (which for the time being, defaults to `true`) implies the following:
1. The (legacy, deprecated) `.flutter-plugins` file is not generated:
https://docs.flutter.dev/release/breaking-changes/flutter-plugins-configuration
2. The (legacy, deprecated) `package:flutter_gen` is not synthetically generated:
https://github.com/flutter/website/pull/11343
(awaiting website approvers, but owners approve this change)
This change creates `useImplicitPubspecResolution` and plumbs it through as a required variable, parsing it from a `FlutterCommand.globalResults` where able. In tests, I've defaulted the value to `true` 100% of the time - except for places where the value itself is acted on directly, in which case there are true and false test-cases (e.g. localization and i10n based classes and functions).
I'm not extremely happy this needed to change 50+ files, but is sort of a result of how inter-connected many of the elements of the tools are. I believe keeping this as an explicit (flagged) argument will be our best way to ensure the default behavior changes consistently and that tests are running as expected.
Documents when to use `throwToolExit` and how to use it.
Replaces every invocation of `throw ToolExit` with `throwToolExit` and makes the former impossible; this is so that every user will at least (hypothetically) have the chance to read the documentation attached to `throwToolExit` (and if we change parameters in the future they will all flow through one place).
Fixes https://github.com/flutter/flutter/issues/157359
Prevents Flutter.xcframework.dSYM from being copied into the App.framework folder. I am not 100% positive if there are cases where it's valid to have multiple dSYMs in that folder, so I'm just string matching and filtering out `Flutter.xcframework.dSYM`
The SourceVisitor uses the engineVersion parameter to determine whether it needs to check for changes to artifacts or if it can assume that artifacts are unmodified from a versioned build of the engine. engineVersion is set based on whether the Artifacts instance sets the isLocalEngine property.
CachedLocalWebSdkArtifacts (instantiated when the --local-web-sdk flag is used) was only setting isLocalEngine if --local-engine was also used. This caused the build system to ignore changes to the files in the locally built flutter_web_sdk when using --local-web-sdk alone.
This PR renames Artifacts.isLocalEngine to usesLocalArtifacts in order to clarify what it means. It also changes CachedLocalWebSdkArtifacts to always enable usesLocalArtifacts.
There have been various requests for this for a while. See https://github.com/flutter/flutter/issues/96283 for an example. This has become more important with dart2wasm builds in the mix, as the profiling versions of the dart2wasm builds are a lot less debuggable than the debug versions. Most of this is already wired up so it just requires taking out a few explicit checks for it and making sure that we compile with the right optimization levels when compiling debug.
This PR addresses an issue where the `--target-platform` flag was not being respected when building APKs in debug mode. Previously, debug builds would always include `x86` and `x64` architectures, regardless of the specified target platform. This change ensures that the `--target-platform` flag is honored across all build modes, including debug.
To achieve this, `BuildApkCommand` has been slightly changed to become responsible for list of archs that should be built in the current run,rather than just parsing arguments. Previously, this responsibility was distributed to gradle, which could be frustrating (in my opinion)
Fixes#153359
Adds `-u`/`--unit-id-debug-info` arguments to `flutter symbolize` to pass paths to DWARF information for deferred loading units. The argument passed via `-u` should be of the form `N:P`, where `N` is the loading unit ID (an integer) and `P` is the path to the debug information for loading unit `N`. The DWARF information for the root loading unit can either be passed by `-d`/`--debug-info` as before or by `--unit-id-debug-info 1:<path>`.
Partial fix for https://github.com/flutter/flutter/issues/137527. Additional work is needed to adjust tools built on top of `flutter symbolize` to store and pass along this additional information appropriately when there are deferred loading units.
This PR modifies the warning message regarding Java compatibility to make it consistent with the Flutter style guide.
**Current message looks like this**
```
[RECOMMENDED] If so, to keep the default AGP version 8.1.0, make
sure to download a compatible Java version
(Java 17 <= compatible Java version < Java 21).
You may configure this compatible Java version by running:
`flutter config --jdk-dir=<JDK_DIRECTORY>`
Note that this is a global configuration for Flutter.
Alternatively, to continue using your configured Java version, update the AGP

Depends on https://github.com/flutter/website/pull/11098
Native libraries that are contributed by native asset builders can depend on each other. For macOS and iOS, native libraries are repackaged into Frameworks, which renders install names that have been written into dependent libraries invalid.
With this change, a mapping between old and new install names is maintained, and install names in dependent libraries are rewritten as a final step.

I am making an assumption `OutputMode.none` should _really_ mean
`OutputMode.failuresOnly`, that is, if we ever get a non-zero exit code,
we still want to know why. If I've somehow misunderstood that, LMK and
I'm happy to revert this PR or make adjustments.
This fixes the bug where if you were to do:
```sh
git clone https://github.com/myuser/fork-of-flutter
cd fork-of-flutter
./bin/flutter update-packages
```
You now get:
1. An actual error message, versus no output at all.
2. A warning that a common reason is not tracking a remote, with
instructions to fix it.
Closes https://github.com/flutter/flutter/issues/148569.
This reverts commit 7cdc23b3e1.
The failure in the `native_assets_test` integration test on Windows was caused by the DevTools process not being shutdown by the `ColdRunner` when running the profile mode portion of the test. This resulted in the test being unable to clean up the project created by the test as DevTools was still holding onto a handle within the directory. This PR adds back the mistakenly removed DevTools shutdown logic in the `ColdRunner`.
1. Instead of getting the `FULL_PRODUCT_NAME` Xcode build setting (`Runner.app`) instead use `PRODUCT_NAME` since most places really want the product name, and the extension stripping wasn't correct when the name contained periods.
2. Don't instruct the user to open the `xcarchive` in Xcode if it doesn't exist.

This change is a major step towards moving away from shipping DDS via Pub.
The first component of this PR is the move away from importing package:dds to launch DDS. Instead, DDS is launched out of process using the `dart development-service` command shipped with the Dart SDK. This makes Flutter's handling of DDS consistent with the standalone Dart VM.
The second component of this PR is the initial work to prepare for the removal of instances of DevTools being served manually by the flutter_tool, instead relying on DDS to serve DevTools. This will be consistent with how the standalone Dart VM serves DevTools, tying the DevTools lifecycle to a live DDS instance. This will allow for the removal of much of the logic needed to properly manage the lifecycle of the DevTools server in a future PR. Also, by serving DevTools from DDS, users will no longer need to forward a secondary port in remote workflows as DevTools will be available on the DDS port.
There's two remaining circumstances that will prevent us from removing DevtoolsRunner completely:
- The daemon's `devtools.serve` endpoint
- `flutter drive`'s `--profile-memory` flag used for recording memory profiles

After this PR, after a completed `flutter build apk` command, we:
- Emit a `manifest-impeller-disabled` command if `io.flutter.embedding.android.EnableImpeller` is `'false'`.
- Emit a `manifest-impeller-disabled` command if `io.flutter.embedding.android.EnableImpeller` is _missing_.
- Emit a `manifest-impeller-enabled` command if `io.flutter.embedding.android.EnableImpeller` is `'true'`.
We will need to change the default (see `_impellerEnabledByDefault` in `project.dart`) before releasing, otherwise we will misreport `manifest-impeller-disabled` at a much higher rate than actual. If there is a way to instead compute the default instead of hard-coding, that would have been good.
See <https://docs.flutter.dev/perf/impeller#android> for details on the key-value pair.

- When `--web-renderer` is omitted, keep the value `null` until it later materializes to either `canvaskit` or `skwasm`.
- No more hardcoded defaults anywhere. We use `WebRendererMode.defaultForJs/defaultForWasm` instead.
- When in `--wasm` mode, the JS fallback is now `canvaskit` instead of `auto`.
- Add test for defaulting to `skwasm` when `--wasm` is enabled.

## 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.
When Swift Package Manager feature is enabled, create app and create plugin will have Swift Package Manager integration already added and will not need to undergo a migration.
Fixes https://github.com/flutter/flutter/issues/146371.

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
This adds support for adding the `--wasm` flag to `flutter run` and `flutter drive`
* Emits errors if you attempt to use the skwasm renderer without the `--wasm` flag
* Emits errors if you try to use `--wasm` when not using a web device
* Uses the skwasm renderer by default if you pass `--wasm` and no `--web-renderer`
Also move the vm service discovery logic into platform-specific implementation of `Device`s. This is to avoid having platform-specific code in attach.dart.
* 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.
This fixes https://github.com/flutter/flutter/issues/126692
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`.
