This flag has been enabled by default for quite some time in `master`,
and in the current `stable`.
This is the first of many PRs to get rid of the flag and the deprecated
code it is guarding.
- Delete code paths that handle screenshots for the HTML renderer
- Delete artifact enums for the HTML/AUTO renderers (and all their
usages).
- Remove HTML/AUTO renderers warnings.
- Delete the HTML/AUTO renderer enums (and all their usages).
- Delete tests for all the above.
Closes https://github.com/flutter/flutter/issues/162846.
At HEAD, including before this PR, it was impossible to use, or pass-in,
an unsound null-safety mode, but we still had code checking for it, and
reported analytics (I think? Some of these are `package:usage` specific
which is defunct).
This PR eradicates the otherwise unused code.
Towards https://github.com/flutter/flutter/issues/162846.
Removes all of the unsound host artifacts, and then uses their name for
the sound artifacts.
That is, for something like `webPlatformDDCKernelDill`, this PR:
- Changes the web GN builders to only emit the sound SDK, without the
`-sound` suffixes
- Deletes `webPlatformDDCKernelDill` and all usages of it (implicitly
unsound, and unused).
- Renames `webPlatformDDCKernelSoundDill` to `webPlatformDDCKernelDill`.
No user impact expected, as there was no way to use the unsound
artifacts from the Flutter tool.
On an internal chat, I asked:
> Is there a reason I don't understand why `flutter` should still
support "unsound" null-safety modes?
@jonahwilliams:
> I don't believe its possible to have non-null safe flutter code.
---
There is quite a bit of code and branches, so to keep the PRs
understandable/approachable, this first PR removes the ability to have
the `DevFS` implementations for the web SDK choose between sound and
unsound null safety, and removes the mapping accordingly.
The enums still exist, but can be cleaned up in a follow-up PR (you'd
want to rename to remove "sound" as well, ideally).

- Uses the `bootstrapScript` field in `loadConfig` to run a script after
all scripts have loaded.
- This script just calls a callback that is set up beforehand and calls
main.
- Modifies the callback that calls `dartDevEmbedder.runMain` to wait
until both DWDS called main and all scripts have loaded.
- Unskips hot reload tests now that the race condition should no longer
exist.

recompile has been split into recompile and recompile-restart in the

recompiles and hot restart recompiles, and therefore emit rejection

- Adds logic to emit newly compiled sources to a file that can be read
by the bootstrapper.
- Adds bootstrapping logic to reload scripts as needed. This involves
implementing the necessary hot restart callback, fetching and processing
the emitted file of newly compiled sources, cache busting, and loading
the scripts onto the page. A lot of this logic is similar or identical
to what we have for internal hot restart support.
- Runs existing hot restart tests with the new bundle format.

This gets us closer to enabling [hot
reload](https://github.com/dart-lang/sdk/issues/54934) on the web as
this format is a prerequisite. Historically, we added support for the
DDC module format only to enable hot reload, but that format is not
feasible for the goal, so we added the DDC library bundle format. The
DDC library bundle format is currently represented as the combination of
the `ddc` module format and `canary`. We no longer need to support the
old DDC module format.
- Adds build artifacts to build the SDKs for this format (but only in
sound mode as unsound is unsupported), and removes said artifacts for
the DDC module format.
- Update artifact maps and constants to add the new format and remove
the old format.
- Adds handling of the `canaryFeatures` flag.
- Update dwds to 24.3.0 and use the new
`FrontendServerDdcLibraryBundleStrategyProvider`.
- Add bootstrap code for the new format. Kept DDC module format
bootstrap code as it's used internally.
- Updates tests.
I ran `spinning_square` with the new module format to verify that it can
run.

Part of https://github.com/flutter/flutter/issues/160043, makes it
easier to add https://github.com/flutter/flutter/pull/160131.
This PR has no functional changes to any of the code, but does refactor
both the code and tests:
- Makes a number of always non-null but not migrated to non-null
properties, well, not-null
- Creates two concrete methods (`update` and `compare` versus a
positional nullable boolean)
- Uses type signatures instead of `String?` to explain the possible
results of the methods
- Renames the mysterious `shellPath` variable to `flutterTesterBinPath`
- Expands and rewrites internally-facing doc comments
- Moves `WebRenderer` environment variable setting to
`flutter_web_platform.dart`
- Makes the tests have less duplication, and check for update/compare
cases
After this PR, I can use it in the non-web branch of the Flutter tool
without any hacks or TODOS :)
/cc @eyebrowsoffire (trivial web refactoring), @camsim99 (changes being
made to tool).
Closes https://github.com/flutter/flutter/issues/158012.
This is (effectively) a user-facing NOP, which is exchanging an
on-by-default command-line argument (`--implicit-pubspec-resolution`)
for an off-by-default global feature flag
(`explicit-package-dependencies`). It matches the mental model better,
is less painstaking to maintain and feed throughout, and will be easier
to globally flip on/off in a future PR.

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)._
_/cc @camsim99 @cbracken @johnmccutchan for visibility on the change._
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.
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.
Fix JS compilation to use the command 'compile js' instead of using
snapshot names to invoke dart2js
The Dart SDK is switching all tools to use AOT snapshots instead of JIT
snapshots and using snapshot names directly causes things to break.
This pull request adds a local function `runInTestbed()` to **devfs_web_ddc_modules_test.dart**, which wraps the `testbed.run()` method. Several whitespace adjustments have been made as well.
<br>
It's much easier to read after clicking "hide whitespace".

Relevant style guidelines:
- Prefer avoiding line breaks after assignment operators.
- If you have a newline after some opening punctuation, match it on the closing punctuation.
- Only use `=>` when everything, including the function declaration, fits on a single line.
If the user specifies the `--no-web-resources-cdn` or `--local-web-sdk`, we should use the local version of CanvasKit. `flutter.js` now has a flag that can be specified in the build configuration that tells it to load locally instead.
Also, added a link to the relevant docs in the web template warnings.
This addresses https://github.com/flutter/flutter/issues/148713
Also fixes https://github.com/flutter/flutter/issues/145559
- 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.
Fixes https://github.com/flutter/flutter/issues/149826
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`
* 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`.
Partial implementation of https://github.com/flutter/flutter/issues/143348
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`.
### 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
Update: Accidentally use `--O4` instead of `-O4` in `dev/devicelab/lib/tasks/web_benchmarks.dart` update.

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.
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:
https://github.com/flutter/flutter/pull/143128https://github.com/flutter/flutter/pull/141396
While doing this revert, I had a few merge conflicts with https://github.com/flutter/flutter/pull/142760, and I tried to resolve the merge conflicts within the spirit of that PR's change, but @chingjun I might need your input on whether the imports I have modified are okay with regards to the change you were making.
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.
Related to:
https://github.com/flutter/flutter/pull/142709https://github.com/flutter/flutter/issues/142041
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.
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.
