downgrade analysis failed failed with 2 errors:

• NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER - lib/src/file_stdio.dart:17:7 - Missing concrete implementations of 'getter class _StdSink implements IOSink.lineTerminator' and 'setter class _StdSink implements IOSink.lineTerminator'.
• NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER - lib/src/file_stdio.dart:106:7 - Missing concrete implementations of 'getter class Stdin extends _StdStream implements Stream<List

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.
