This is the initial tooling work for Flutter Widget Previews, adding two
commands: `flutter widget-preview start` and `flutter widget-preview
clean`.
The `start` command currently only checks to see if
`.dart_tool/widget_preview_scaffold/` exists and creates a new Flutter
project using the widget_preview_scaffold template if one isn't found.
The widget_preview_scaffold template currently only contains some
placeholder files and will be updated to include additional code
required by the scaffold.
The `clean` command simply deletes `.dart_tool/widget_preview_scaffold/`
if it's found.
This change also includes some refactoring of the `create` command in
order to share some project creation logic without requiring `flutter
widget-preview start` to spawn a new process simply to run `flutter
create -t widget_preview .dart_tool/widget_preview_scaffold`.

This PR introduces a `NativeAssetsManifest.json` next to the
`AssetManifest.bin` and `FontManifest.json`. This removes the need for
embedding the native assets mapping inside the kernel file and enables
decoupling native assets building and bundling from the kernel
compilation in flutter tools. This means `flutter run` no longer does a
dry run of `hook/build.dart` hooks.
(It also means all isolate groups will have the same native assets.
However, since Flutter does not support `Isolate.spawnUri` from kernel
files, this is not a regression.)
Implementation details:
* g3 is still using kernel embedding.
https://github.com/flutter/flutter/pull/142016 introduced an argument to
embed a `native_assets.yaml` inside `flutter attach` and `flutter run`
(the outer flutter process), but it is not used in `flutter assemble`
(the inner process when doing `flutter run`). So, those arguments need
to still be respected. However, all other logic related to embedding a
yaml encoding in the kernel file has been removed.
* All dry-run logic has been removed. 🎉
* The `KernelSnapshot` target no longer depends on the
`InstallCodeAssets` target. Instead, the various OS-specific
"BundleAsset" targets now depend on the `InstallCodeAssets` target. The
`InstallCodeAssets` invokes the build hooks and produces the
`NativeAssetsManifest.json`. The various "BundleAsset" commands
synchronize the `NativeAssetsManifest.json` to the app bundle.
* `InstallCodeAssets` produces a `native_assets.json`, which is renamed
to `NativeAssetsManifest.json` in the various "Bundle" targets. This
means that all unit tests of the "Bundle" targets now need to create
this file. (Similar to how `app.dill` is expected to exist because
`KernelSnapshot` is a dependency of the "Bundle" targets.)
* Because dynamic libraries need to be code signed (at least on iOS and
MacOS), the bundling of the dylibs is _not_ migrated to reuse
`_updateDevFS` (which is used for ordinary assets). Only the 2nd and 3rd
invocation of `flutter assemble` from `xcodebuild` has access to the
code signing identity.
Relevant tests:
* test/integration.shard/isolated/native_assets_test.dart - runs
`flutter run` with native assets including hot restart and hot reload.
TODO:
* Undo engine-roll in this PR after engine has rolled in.

Cleans up https://github.com/flutter/flutter/pull/155800. In summary, `ResidentRunner`/`FlutterDevice` have branching behavior around logging that depends on the type of `DeviceLogReader` on the `FlutterDevice` instance. Let's instead move this behavior to the `DeviceLogReader` implementations.
My apologies for the large diff. Much of this is a refactor that was a bit too difficult to separate into its own commits.
Here are the main two changes
* Replaces the mutable `connectedVmService` field on the `DeviceLogReader` class with a new method `provideVmService`. This serves largely the same purpose as the mutable field, but it allows for asynchronous code. This is where we put the logic that used to exist in `FlutterDevice.tryInitLogReader`.
* Removes the `tryInitLogReader` method from `FlutterDevice`. This method served to set the `appPid` field on the `FlutterDevice`'s `DeviceLogReader` instance. This was only used in the case of Android to filter out logs unrelated to the flutter app coming from the device, so we can move this logic to `AdbLogReader`'s implementation of `provideVmService`.
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.

I am guessing <https://api.flutter.dev/flutter/dart-io/ProcessInfo/maxRss.html> is not guaranteed to be stable while running, and as a result is not. This stabilizes the value for a test that I believe does not care about getting the "real" value anyway.
Removes duplicated constants and ensures consistency by using package:vm_service as a source of truth for RPC error codes for requests made with package:vm_service.

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.
Two of the tests, `test_test` and `break_on_framework_exceptions`, no longer appear to leak (without changes). Perhaps underlying infrastructure has changed, or some other bug in the tool itself was fixed in meantime.
`packages_test` required resetting `Cache.flutterRoot`.

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`
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.
Now that Flutter requires AGP 7+, we can use Java 11 as the compatibility version in the plugin template rather than 1.8, avoiding warnings with newer toolchains, and we can remove the check for 'namespace' existing that was only necessary to support AGP 4.1.

Migrates existing instantions of `--template plugin_ffi` to deal with Android 15 16kb memory pages.
Issue:
* https://github.com/flutter/flutter/issues/155933
@reidbaker I could only find migrations that run from the root application. However the file needing to be migrated is a plugin. The plugin is being referenced from the example in the example dir and that's where the migrator is run, so I wrote the code so that it walks up to find the plugin. Do you know of a way to run migrators to non-root projects? (Can we even safely do so, e.g. the non-root could be in the pub cache, could be a different project on the users' system etc. So maybe checking if we are in the examples dir is the only sane thing to do?)
Tests:
* Added unit tests in `test/general.shard/android/migrations/cmake_android_16k_pages_migration_test.dart`
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)

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
version specified in the following files to a compatible AGP
version (minimum compatible AGP version: 7.0) as necessary:
- /home/user/project/testproj/android/build.gradle
See
https://developer.android.com/build/releases/gradle-plugin for details on
compatible Java/AGP versions.
```
**After Modification**
```
To keep the default AGP version 8.1.0, download a compatible Java version
(Java 17 <= compatible Java version < Java 21). Configure this Java version
globally for Flutter by running:
flutter config --jdk-dir=<JDK_DIRECTORY>
Alternatively, to continue using your current Java version, update the AGP
version in the following file(s) to a compatible version (minimum AGP version: 7.0):
/home/user/project/testproj/android/build.gradle

Depends on https://github.com/flutter/website/pull/11098
Re-lands https://github.com/flutter/flutter/pull/136880, fixes https://github.com/flutter/flutter/issues/136879.
Additions to/things that are different from the original PR:
- Adds an entry to `gradle_errors.dart` that tells people when they run into the R8 bug because of using AGP 7.3.0 (https://issuetracker.google.com/issues/242308990).
- Previous PR moved templates off of AGP 7.3.0.
- Packages repo has been moved off AGP 7.3.0 (https://github.com/flutter/packages/pull/7432).
Also, unrelatedly:
- Deletes an entry in `gradle_errors.dart` that informed people to build with `--no-shrink`. This flag [doesn't do anything](https://github.com/flutter/website/pull/11022#issuecomment-2297294421), so it can't be the solution to any error.
- Uniquely lowers the priority of the `incompatibleKotlinVersionHandler`. This is necessary because the ordering of the errors doesn't fully determine the priority of which handler we decide to use, but also the order of the log lines. The kotlin error lines often print before the other error lines, so putting it last in the list of handlers isn't sufficient to lower it to be the lowest priority handler.
