## Directory contents The Dart files and golden master `.expect` files in this directory are used to test the [`dart fix` framework](https://dart.dev/tools/dart-fix) refactorings used by the Flutter framework. See the flutter/packages/flutter/lib/fix_data.yaml file for the current package:flutter data driven fixes. ## When making structural changes to this directory Note that the tests in this directory are also invoked from external repositories. Specifically, the CI system for the dart-lang/sdk repo runs these tests in order to ensure that changes to the dart fix file format do not break Flutter. See [tools/bots/flutter/analyze_flutter_flutter.sh](https://github.com/dart-lang/sdk/blob/master/tools/bots/flutter/analyze_flutter_flutter.sh) for where the tests are invoked. When possible, please coordinate changes to this directory that might affect the `analyze_flutter_flutter.sh` script.
