My understanding is that, similar to pkg/meta's @required, @alwaysThrows has no use in Dart v3:

// Dart v2 before null-safety
import 'package:meta/meta.dart';

@alwaysThrows
void a() => throw 'Always throws';

// Dart v2 after null-safety
Never a() => throw 'Always throws';

Anyone, not sure... figured I'd highlight this for others to look at.

That's probably reasonable. The only place I can think of where the annotation can be used that Never can't be used is on a setter, but it seems highly unlikely that anyone's using the annotation on a setter.

Oops, done.
