Restricted Generic Type (T Extends SomeClass) Problem

[Peng-Qian]

Problem

when generating the restricted generic type as follow, the dynamic will filled in and result in exceptions

Annotation

@injectable
class Repository<T extends Entity> {
  ...
}

Generated code

  gh.factory<Repository<dynamic>>(() => Repository<dynamic>());

which will not compile...

@Peng-Qian I see. This should normally register without a type? how would you manually register it?

I think the problem here is that you cannot know what T is when registering and get_it does not provide a way to know either. IMO the best workaround for this is to register a factory class instead.

@injectable
class RepositoryFactory {
    Repository<T> getRepositoryFor<T>() => Repository<T>();
}

Which you can then use as GetIt.instance.get<RepositoryFactory>.getRepositoryFor<MyEntity>()
