downgrade analysis failed failed with 2 errors:

• EXPERIMENT_NOT_ENABLED_OFF_BY_DEFAULT - lib/src/async/async_resource_manager.dart:8:28 - This requires the experimental 'variance' language feature to be enabled.
• EXPERIMENT_NOT_ENABLED_OFF_BY_DEFAULT - lib/src/sync/resource_manager.dart:7:23 - This requires the experimental 'variance' language feature to be enabled.

Run dart pub downgrade and then dart analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
