super params: Invalid argument(s): Type parameter TypeParameter(MultiRootFileSystemEntity.D) is not indexed #48708
Description
After migrating flutter_tools to use super parameters, one of its tests is failing with:

To reporduce:
- Check out Prepare
flutter_toolsforuse_super_parametersflutter/flutter#100509 - cd into flutter_tools:
cd packages/flutter_tools - run the test:
dart run test test/general.shard/project_file_invalidator_test.dart
So far I have sadly been unable to reproduce this issue on a smaller scale outside of the PR, but flutter's adaptation of super parameters is blocked on this.
