In a number of discussions (dart-lang/sdk#46218, dart-lang/sdk#58348), Flutter team members have indicated that they would use an @awaitNotRequired annotation if it were available, to annotate Future-returning functions that do not need to be awaited or wrapped in unawaited().

In the next release of the meta package, 1.17.0, we'll be releasing @awaitNotRequired.

I'm just creating this issue to track adding @awaitNotRequired annotations to everywhere in the Flutter SDK that we wanted them. In dart-lang/core#742, @goderbauer mentioned https://api.flutter.dev/flutter/animation/AnimationController/forward.html.
