The following code fails to run with flutter test --platform=chrome test/pure_dart_test.dart under Dart 3.0:

test/pure_dart_test.dart:

import 'package:test/test.dart';

void main() {
  test('calculate', () {
    Foo().buildOverscrollIndicator(TargetPlatform.android, AndroidOverscrollIndicator.glow);
  });
}

class Foo {
  int buildOverscrollIndicator(TargetPlatform platform, AndroidOverscrollIndicator indicator) {
    switch (platform) {
      case TargetPlatform.iOS:
      case TargetPlatform.linux:
      case TargetPlatform.macOS:
      case TargetPlatform.windows:
        return 1;
      case TargetPlatform.android:
        switch (indicator) {
          case AndroidOverscrollIndicator.stretch:
            return 2;
          case AndroidOverscrollIndicator.glow:
            continue glow;
        }
      glow:
      case TargetPlatform.fuchsia:
        return 3;
    }
  }
}

enum AndroidOverscrollIndicator {
  stretch,
  glow,
}

enum TargetPlatform {
  android,
