The .yaml files in these directories are used to define the dart fix framework refactorings used by flutter_test.
The number of fix rules defined in a file should not exceed 50 for better maintainability. Searching for title: in a given .yaml file will account for the number of fixes. Splitting out fix rules should be done by class.
When adding a new .yaml file, make a copy of template.yaml. Each file should be for a single class and named fix_<class>.yaml. To make sure each file is grouped with related classes, a fix_<filename> folder will contain all of the fix files for the individual classes.
See the flutter/packages/flutter_test/test_fixes directory for the tests that validate these fix rules.
To run these tests locally, execute this command in the flutter/packages/flutter_test/test_fixes 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 flutter fix tests are invoked for the dart repo.
See dev/bots/test.dart for where the flutter fix tests are invoked for the flutter/flutter repo.
When possible, please coordinate changes to this directory that might affect the analyze_flutter_flutter.sh script.
