By default, `CoverageCollector.libraryNames` was being set to the name
of the current `FlutterProject`. This means that only tests in the
current project are included in the coverage report. So if the project
is a workspace, tests in its subprojects were being excluded. I've
changed it so that it also allows tests that are part of any of the
subprojects.
Fixes#159390
Adds a new `widget_preview_scaffold.shard` directory which contains a
hydrated `widget_preview_scaffold` template. This will allow for us to
write widget tests against the widgets defined in the templates.
This PR doesn't add any widget tests and is only adding the ability to
run these tests in follow up changes.
Fixes https://github.com/flutter/flutter/issues/166416
Updating the dart-lang/native dependencies to the ones published today.
No functional changes, but `CodeAsset` does not expose an `architecture`
and `os ` anymore (https://github.com/dart-lang/native/issues/2127).
Instead these should be taken from what is passed in for the
`CodeConfig`. This PR refactors the `DartBuildResult` to carry around
the `Target` with `CodeAsset`s as `FlutterCodeAsset`s.
(This PR avoid refactoring relevant code due to
https://github.com/flutter/flutter/pull/164094 already refactoring this
code.)
Unfortunately `10_google3_bug.yml` comes before `2_bug.yml`.
This changes the name (slightly) of the issue templates based on the
instructions from GitHub on what to do when you have 10+ issue templates
(as a side-note: I wonder if we need/still use umbrella bugs for the
feature tracker, or two types of performance bugs)
In the case of a multi-app scenario, different applications may store
files in different locations. In order to avoid reloading files that
were unchanged, a suffix can be added to indicate which "version" of
this file we're loading. Even if it has a different path, because the id
and "version" (which is URL(...).search) are the same, the file would
not be reloaded.
With Flutter tools, this scenario doesn't occur. The running application
ultimately does not need to worry about the same file in different
locations.
The benefit to avoid this caching is that the user only ever sees one
copy of every file, which is the latest version, instead of the current
behavior where a "gen=N" suffix is added to a newer version.
Note that this is unrelated to the XHR or its headers or any of its
caching mechanisms. The XHR is only used to fetch the *list* of changed
files, not the files themselves. The files get loaded as part of the
`appendChild` call.

```
1. Converts the `app_plugin_loader.groovy` to kotlin source.
2. Converts the `module_plugin_loader.groovy` to kotlin script. This
can't be changed to kotlin source yet, as we will need to instruct users
to make a change to their host app-level gradle files before we can turn
down script application of this separate gradle plugin. This is a
breaking change, and will need a quarter at least of notice.
3. Unfortunately, the main Flutter Gradle plugin depends on being able
to call methods of the `native_plugin_loader`, which we could do in
groovy via wacky dynamic behavior, calling across the compiled
plugin->script plugin barrier. We can't do this in Kotlin source, and we
also can't fully convert `native_plugin_loader` to kotlin source yet
because of (2), so I've added a `NativePluginLoaderReflectionBridge`
that allows us to access the methods in the
`native_plugin_loader.gradle.kts` from the Kotlin source files, calling
across the compiled plugin->script plugin barrier as we were before.
The plan here is
1. to follow up by adding a converted `native_plugin_loader.gradle.kts`
in Kotlin source, and migrating all paths but the host-app using a
module-as-source to use the converted approach (but not deleting the old
way)
2. maintaining both ways for a release or two, with the script
application printing a message notifying users to update to the
non-script based application of the `module_plugin_loader`.
3. Then we can delete the script based apply, and also the reflection
bridge.

`FlutterCommand` which handles file paths provided in the positional
argument list.

This change reworks how users define previews in their code, expands the
number of valid 'functions' that can be used to create previews, and
allows for specifying a 'wrapper' function to wrap the previewed widget
with
The `WidgetPreview` class has been removed from the framework, with its
properties being added to the `Preview` annotation class instead to
remove some boilerplate from the preview declaration workflow.
Before:
```dart
@Preview()
List<WidgetPreview> previews() => <WidgetPreview>[
WidgetPreview(
name: 'Top-level preview',
child: Text('Foo'),
),
];
```
After:
```dart
@Preview(name: 'Top-level preview')
Widget previews() => Text('Foo');
```
Previews can now be defined using top-level functions, constructors and
factories which take no arguments, and static methods within classes:
Examples:
```dart
@Preview(name: 'Top-level preview')
Widget previews() => Text('Foo');
class MyWidget extends StatelessWidget {
@Preview(name: 'Constructor preview')
MyWidget.preview();
@Preview(name: 'Factory preview')
factory MyWidget.factoryPreview() => MyWidget.preview();
@Preview(name: 'Static preview')
static Widget previewStatic() => Text('Static');
@override
Widget build(BuildContext context) {
return Text('MyWidget');
}
}
```
Users can also provide a `wrapper` function with the signature `Widget
Function(Widget)` to easily wrap previewed widget with shared
bootstrapping logic.
Example:
```dart
Widget testWrapper(Widget child) {
return Provider<int>.value(
value: 42,
child: child,
);
}
@Preview(name: 'Preview with wrapper', wrapper: testWrapper)
Widget preview() {
return Text('Attributes');
}
```
Which is effectively the same as:
```dart
@Preview(name: 'Preview with wrapper')
Widget preview() {
return Provider<int>.value(
value: 42,
child: Text('Attributes'),
);
}
```
Finally, for situations where a `BuildContext` is needed, users can
return a `WidgetBuilder` from their preview function:
```dart
@Preview('Builder preview')
WidgetBuilder builderPreview() {
return (BuildContext context) {
// TODO: retrieve state from context.
return Text('Foo');
};
}
```
I would recommend changing the propety mock so that the properties are
given as strings and not constants, otherwise you can run into problems
like this where the mock does exactly what you want :)
Also use the name "gen_snapshot" when building for Android targets
instead of appending a target architecture to the filename.
This allows flutter_tools to find the universal gen_snapshot binary when
using a locally built engine. Previously the tools would search
directories like "clang_x64" and find build outputs that may not match
the host architecture.
Moving the universal gen_snapshot binary to a separate directory avoids
conflicts with Dart's gen_snapshot binary, which is placed at the root
of the target output directory.
https://github.com/dart-lang/webdev/issues/2584
Reassemble was being called in DWDS in the injected client until
v24.3.7. Flutter tools should now instead be the one to call the service
extension. Now that it's in Flutter tools, we can also report how long
it took. Similarly, we should update analytics on various things like,
whether there was a reload rejection, how long the compile took, and
more.
Adds test to check that these analytics are being reported correctly.

The path to reload scripts JSON was being added to the global window
before. It should instead be passed to the provider on setup. In order
to do this, the baseUri calculation is moved into the WebAssetServer.
This is safe because Flutter tools was calculating it immediately
after creating the server anyways.
https://github.com/dart-lang/webdev/issues/2584
Existing hot reload tests should test this behavior.

Ignore return value from eglinfo - it doesn't indicate failure.
Discovered when using an X11 system where Wayland is not available. It
returns 1 in this case, but the output is still valid. Confirmed by
looking at the eglinfo source - we should parse the output regardless of
what it returns.
Catch exception correctly when eglinfo is not installed.
Fixes for https://github.com/flutter/flutter/pull/163980
I have attempted to cherry pick some useful information from eglinfo
which is often requested when resolving issues with rendering.
This information is not required to compile an Flutter application, so
it is a little different to the other displayed information.
Closes https://github.com/flutter/flutter/issues/160257.
~~This will sit on CI for a bit and give me a better idea of how much
work there is to do.~~ Done!
## IMPORTANT: Do **not** revert on 1-2 isolated post-submit failures.
While I've spent the last several weeks getting this passing all
presubmit tests, and some integration tests I suspected might be
affected, it is possible that there are 1-2 integration tests that will
fail as a result of landing this PR. I'll disable the flag
(`--no-explicit-package-dependencies`) if the failures look obvious
enough, otherwise I'll revert.

Before this PR, the macOS workflow (or, others, but only macOS had a

This makes various Flutter version information available at runtime.
It's basically the same as executing `flutter --version`. This is
especially useful for tools like Crashlytics or Sentry (see for example
https://github.com/getsentry/sentry-dart/issues/416).
Usage example:
```dart
FlutterVersion.version; // 3.16.5
FlutterVersion.channel; // stable
FlutterVersion.gitUrl; // https://github.com/flutter/flutter.git
FlutterVersion.frameworkRevision; // 78666c8dc5
FlutterVersion.engineRevision; // 3f3e560236
FlutterVersion.dartVersion; // 3.2.3
```
This approach has prior art as seen in #134179.

If the Flutter SDK is updated we need to invalidate the widget preview
scaffold project to, at the very least, rebuild the precompiled
application. Similarly, if the root project's `pubspec.yaml` is updated,
the scaffold project's pubspec should be regenerated.
This change adds a `preview_manifest.json` to the scaffold project which
contains information related to:
- The manifest schema version
- The Dart SDK version the project was generated with
- The last known hash of the root project's pubspec.yaml
This information is used to determine whether or not the scaffold
project needs to be regenerated or the scaffold pubspec needs to be
updated to reflect changes to the root project's pubspec since the
previewer was last run.

Closes https://github.com/flutter/flutter/issues/162399.
Closes https://github.com/flutter/flutter/issues/163272.
`refreshPluginsList` is commonly called in iOS/macOS apps, more times
than you expect (and load bearing);
https://github.com/flutter/flutter/issues/157391.
With `--explicit-package-dependencies`, we no longer write (or compare)
the output of `.flutter-plugins`. The iOS/macOS workflows required `pod
install` output to be invalidated when plugins when change, but the
logic that was being used to see if plugins changed _only_ worked for
the `.flutter-plugins` file format.
In the original code:

As you can see, `pluginsChanged =
oldPluginsFileStringContent.contains(pluginsMap.toString());` was
_always_ `false`, but we never knew because we'd always just fall back
to using the `.flutter-plugins` content comparison (which always
worked).
I added a test as well.
This also appears to fix

The existing code assumed that DWDS needed to initialize some of the JS
state between adding all the scripts to queue and when they are loaded.
A closer examination of the existing AMD module format bootstrapper
shows that we already only initialize DWDS' JS state after all the
scripts are loaded. This is because it waits for the entrypoint to be
loaded before initializing that state, and the entrypoint is only loaded
after all its dependencies are loaded, which includes the SDK and
transitively every file in the app.
Since it's simpler and avoids the double-gating to call main, this
change moves that initialization to after all the scripts are loaded and
aligns with the AMD module bootstrapper.

`flutter widget-preview start --web` will cause the widget preview
scaffold to be run as a Flutter Web application using experimental hot
reload support. This will eventually be the default, with the desktop
environment being put behind a flag for use as a fallback under the
assumption that the desktop environment will be removed in the future.
- Adds better instructions for hot reload (if using the right flags),
hot restart, quitting, clearing, and more. These were already being
printed when using the VM, so this aligns with that.
- Adds an extra parameter for `CommandHelp` to `ResidentRunner` so
`ResidentWebRunner` can pass a version of it that uses its separate
logger and not `globals`. In order to support this, classes up the stack
also provide a `Terminal`, `Platform`, and `OutputPreferences`.
- Fixes up use of `globals` from an earlier change to implement hot
reload to use the logger instead. Same with `globals.platform`.
- Adds tests to check that only hot restart is printed when not using
the extra front-end flags, and both hot restart and hot reload is
printed when you are.

I happened to run into this while chasing other bugs, and noticed
`.flutter-plugins-dependencies` is omitted.
I am guessing this is probably quite stale, but something something
[Chesterton's
fence](https://en.wiktionary.org/wiki/Chesterton%27s_fence), and added
tests.
- 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.
`generateLocalizations` should fail (`flutter gen-l10n`) if `flutter:
generate:` does not exist.
The previous logic was faulty, because it was totally possible to
opt-out of synthetic packages (i.e. in a `l10n.yaml` file), but still
not be specifying `flutter: generate:`, which I _believe_ is supposed to
still be an error.
This came up in https://github.com/flutter/flutter/pull/160289 as
`flutter config --explicit-package-dependencies` is enabled by default,
as the error is no longer thrown. Made a few other small test
forward-fixes that otherwise would break with the switch (but are
expected) as well.
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.
Closes https://github.com/flutter/flutter/issues/162704.

I expect I'll have to update some iOS/macOS unit and possibly
integration tests due to this change, but wanted something concrete to
talk about during our 1:1. Feel free to leave comments or questions even
if this PR is in "draft".
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.
With this change, `flutter widget-preview start` will launch a working
widget preview environment that can render previews from a target
project.
Also fixes an issue where `--offline` wasn't being respected by some pub
operations.
Rather than ask users to pass the complicated and long string
`--extra-front-end-options=--dartdevc-canary,--dartdevc-module-format=ddc`
we want a simpler flag to enable the new DDC module system/hot reload.
Technically this flag enables the new module system, not necessarily hot
reload directly. But we only expect people to use the flag to enable hot
reload so I've chosen the name based on that.

SkSL precompilation was only ever beneficial for iOS. For other
platforms, we recommended against it as Skia generated shaders per
target architecture which could be invalid on other devices. It is no
longer possible to use Skia on iOS.
Delete all Skia shader bundling logic.
Fixes https://github.com/flutter/flutter/issues/80091
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).
Powered by the new and amazing `unnecessary_ignore` lint.
We're not enabling this lint by default because being able to
temporarily use ignores that don't ignore anything is a powerful tool to
enable migrations. We should turn this lint on locally periodically,
though, and clean up all outdated ignores.
This also wires up the preview detector to trigger hot reloads when new
previews are detected or previews are removed.
Note: while this change results in lib/generated_preview.dart being
generated and updated, it's not currently referenced by lib/main.dart
and the preview environment will render a black screen.

- 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
errors only on hot reload.

There's a general timing error that may occur when loading scripts,
where main might be run before the scripts are done loading, leading to
a crash. These tests test that output is being printed to stdout, and
wait forever for that, leading to timeouts. This is flaky, so the race
condition may or may not occur.

- Updates restart/reload code to accept a resetCompiler boolean to
disambiguate between whether this is a full restart and whether to reset
the resident compiler.
- Adds code to call reloadSources in DWDS and handle the response
(including any errors).
- Adds code to invoke reassemble.
- Adds code to emit a script that DWDS can later consume that contains
the changed sources and their associated libraries. This is used to hot
reload. The bootstrapper puts this in the global window. DWDS should be
updated to accept it in the provider itself. See
https://github.com/dart-lang/webdev/issues/2584.
- Adds code to parse module metadata from the frontend server. This is
identical to the implementation in DWDS % addressing type-related lints.
- Adds tests that run the existing hot reload tests but with web. Some
modifications are mode, including waiting for Flutter runs to finish
executing, and skipping a test that's not possible on the web.
Needs DWDS 24.3.4 to be published first and used before we can land.

@camsim99 discovered these would fail here:

This fixes in preparation for the flag flipping, and also fixes a bug in
resolving `synthetic-package` I missed (it _can't_ be true if
`--explicit-package-dependencies` is set).

This change reverts the following previous change:
`flutter widget-preview start` will now look for functions annotated
with `@Preview()` within the developer's project. These functions will
be used to generate
`.dart_tool/widget_preview_scaffold/lib/generated_preview.dart`, which
inserts the returned value from each preview function into a
`List<WidgetPreview>` returned from a `previews()` method that is
invoked by the widget preview scaffold root.
**Example generated_preview.dart:**
```dart
// ignore_for_file: no_leading_underscores_for_library_prefixes
import 'package:foo/foo.dart' as _i1;
import 'package:foo/src/bar.dart' as _i2;
import 'package:widget_preview/widget_preview.dart';
List<WidgetPreview> previews() => [_i1.preview(), _i2.barPreview1(), _i2.barPreview2()];

- 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.
- Adds meta tag to run with utf-8 like in
https://github.com/flutter/flutter/pull/161493.
- Uses DWDS 24.3.3.

We occasionally break ourselves, our users, and the Dart up (or is it
down? side-ways) stream repos (i.e. HHH) when we change how the
undocumented
[`update_engine_version.sh`](https://github.com/flutter/flutter/blob/master/bin/internal/update_engine_version.sh)
script, and it's Windows counterpart
[`update_engine_version.ps1`](https://github.com/flutter/flutter/blob/master/bin/internal/update_engine_version.ps1)
work, but have no way of knowing until N days/weeks later when someone
tells us.
For example,
<https://flutter-review.googlesource.com/c/recipes/+/62400>.
This is my attempt to encode "this is what you can guarantee by calling
this script".
It _still_ will be an internal only API that we might rev at any time,
but at least we:
1. Can tell the Dart team "this is tested and how it works"
2. If we want to change it, the tests will keep us from changing it
without informing folks it changed
These tests should (in theory) cover both Linux/MacOS and Windows.
