Directory contents
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

When making structural changes to this directory
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.
