Full context https://github.com/flutter/flutter/issues/148004 TL;DR 1. Because `package:macros` depends on `package:_macros` via [a Dart SDK dependency](https://github.com/dart-lang/sdk/blob/main/pkg/macros/pubspec.yaml#L13); and 2. `package:macros` exactly pins `package:_macros`; and 3. Each new version of `package:macros` will increment its exact pin of `package:_macros` ([comment](https://github.com/flutter/flutter/issues/148004#issuecomment-2103099893)); and 4. The [flutter/flutter](https://github.com/flutter/flutter) repository exactly pins the Dart SDK (via its exact pin on the [flutter/engine](https://github.com/flutter/engine) repository Therefore, the [flutter/flutter](https://github.com/flutter/flutter) repository effectively pins both `package:macros` and `package:_macros` already (as in, there exists only a single version of each that pub will successfully be able to solve within the context of a particular Flutter SDK). Therefore, it is safe for [flutter/flutter](https://github.com/flutter/flutter) repository to *not* pin `package:macros`, which will allow engine -> framework rolls that contain a new Dart SDK that contains a new `package:_macros` version to land automatically, provided all tests pass.
Flutter Examples
This directory contains several examples of using Flutter. To run an example,
use flutter run
inside that example's directory. See the getting started
guide to install the flutter
tool.
For additional samples, see the
flutter/samples
repo.
Available examples include:
-
Hello, world The hello world app is a minimal Flutter app that shows the text "Hello, world!"
-
Flutter gallery The flutter gallery app no longer lives in this repo. Please see the gallery repo.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
-
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.dev/platform-channels/.
-
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.
Notes
Note on Gradle wrapper files in .gitignore
:
Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
