Enhanced enums in Flutter don't get covered

[alberto-sf]

I have this enum in a file:

enum VegaRadioSize {
  small(27, 18),
  large(36, 22);
  final double normalSize;
  final double pressedSize;
  const VegaRadioSize(this.normalSize, this.pressedSize);
}

It is tested in this way:

group('VegaRadioSize test', () {
    test('Smoke', () {
      expect(VegaRadioSize.values.length, equals(2));
    });

    test('Large test', () {
      expect(VegaRadioSize.large.normalSize, equals(36));
      expect(VegaRadioSize.large.pressedSize, equals(VegaSpacings.space4));
    });

    test('Small test', () {
      expect(VegaRadioSize.small.normalSize, equals(27));
      expect(VegaRadioSize.small.pressedSize, equals(VegaSpacings.space3));
    });
  });

When running flutter test --coverage, the following result appears:

Is this expected? How can I fully cover the enum?

This is fixed in Dart 2.18, which is releasing soon.
