We have deprecated @FfiNative and introduced @Native annotations in Dart.

This has made the Flutter engine build fail:

 info - compositing.dart:37:4 - 'FfiNative' is deprecated and shouldn't be used. Use Native instead. Try replacing the use of the deprecated member with the replacement. - deprecated_member_use
...

We can either:

a. Fix forward and land the migration in the engine, or
b. remove the deprecated annotation in the Dart SDK for now, and then do (a) with a bit more peace, or
c. revert the whole change in the Dart SDK (that's probably a bit too much).
