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._
This PR introduces the `dartFileName` parameter for platform plugin configurations with Dart platform implementations. This new parameter allows plugin developers to specify a custom path to the file where the `dartPluginClass` is defined.
**Implementation is opt-in**. `dartFileName` is completely optional and is taken in account only with `dartClassName`. Possibility to set `dartClassName` without `dartFileName` remains.
**Implementation is backward compatible** â existing configurations using only `dartClassName` remain fully supported. If `dartFileName` is omitted, the system falls back to the previous behavior of deriving the file name from the plugin name.
## Example
```yaml
flutter:
plugin:
platforms:
some_platform:
dartPluginClass: MyPlugin
dartFileName: 'src/my_plugin_implementation.dart'
```
fixes#152833
These changes allow to override existing native endorsed (federated & inline) plugins with e.g. non-endorsed plugin implementations via direct dependencies as described in the section *Platform implementation selection* in the [design doc](https://docs.google.com/document/d/1LD7QjmzJZLCopUrFAAE98wOUQpjmguyGTN2wd_89Srs).
```yaml
# pubspec.yaml
name: example
dependencies:
my_plugin: ^0.0.1
my_plugin_android_alternative: ^0.0.1
```
Closes#80374, closes#59657
Related: Override Dart plugins (#87991, #79669)
Part of #137040 and #80374
- Extracted getting plugin implementation candidates and the default implementation to its own method
- Extracted resolving the plugin implementation to its own method
- Simplify candidate selection algorithm
- Support overriding inline dart implementation for an app-facing plugin
- Throw error, if a federated plugin implements an app-facing plugin, but also references a default implementation
- Throw error, if a plugin provides an inline implementation, but also references a default implementation
Part of #137040 and #80374
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".
Part of #137040 and #80374
- Differentiate pubspec and resolution errors
- Rename platform to platformKey
- Add TODO for rework logic of flag [throwOnPluginPubspecError]
- Swap for loop: handle by platform and then by plugin
I continued [my mission](https://github.com/flutter/flutter/pull/141431) to find as many typos as I could. This time it's a smaller set than before.
There is no need for issues since it's a typo fix.
* Starts using the `--source` flag to compile the dart registrant.
* updated general.shard tests
* Fixed the resident compiler flow
* added integration test
* made the integration test self contained
* renamed generated_main to dart_plugin_registrant
* cleaned up for review
* added task runner for ci
* added bringup and TESTOWNERS
* updated failure message
Building an application for a desktop platform that transitively included any Dart-based plugins (such as path_provider) broke `flutter test`, because its compilation was overriding the provided main (in this case, the test main) with `generated_main.dart` if it was present. This PR:
- Changes the `flutter test` compilation path to update `generated_main.dart`, so that the tests will work, and will include any registered Dart plugins.
- Makes using `generated_main.dart` during recompile opt-in, to try to reduce the chance of a similar bug happening with other codepaths in the future.
