Extend EnumClass?

[cpboyd]

Potentially related to #57 and #58.

My specific use case is that I'm using a EnumClasses to specify navigation paths within a Flutter application.

There is, however, replicated code across classes that I could alleviate if I could have an intermediate abstract class EnumRoute extends EnumClass {}

Would it be possible to have the isEnumClass check use name.startsWith('Enum') (similar to isBuiltValue)?

Could you make EnumRoute a mixin? Then the change would be to allow you to write Foo extends EnumClass with EnumRoute ... not sure if that's allowed today.

@dave26199 I tried that, but since I define field getters, e.g.:

String get title;

I'm then unable to use a const constructor.

Perhaps that's an issue worth raising over at dart-lang since I don't actually have any fields... Just getters (which I suppose I could just turn into functions).

Looks like you found an SDK bug :)

I'll close this then, since a mixin would work fine for my use case.
