The Dart files and golden master .expect files in this directory are used to test the dart fix framework refactorings used by the Flutter framework.
See the flutter/packages/flutter/lib/fix_data directory for the current package:flutter data-driven fixes.
To run these tests locally, execute this command in the flutter/packages/flutter/test_fixes directory.
dart fix --compare-to-golden
For more documentation about Data Driven Fixes, see https://dart.dev/go/data-driven-fixes#test-folder.
To learn more about how fixes are authored in package:flutter, see https://github.com/flutter/flutter/wiki/Data-driven-Fixes
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 for where the tests are invoked.
When possible, please coordinate changes to this directory that might affect the analyze_flutter_flutter.sh script.
