Hi @Karatla 👋

Please have a look at repository provider documentation for a quick intro.

RepositoryProvider allows you to pass an instance of a repository to a sub-tree from where you can access it via context.repository<YourRepositoryType>().
A typical use case is to inject a repository into a bloc:

RepositoryProvider(
          create: (context) => UserRepository(),
          child: BlocProvider(
            create: (context) => AuthBloc(
              userRepository: context.repository<UserRepository>(),
            ),
            child: ...,
          ),
        )

RepositoryProvider is a specialized widget used to provide a repository while the BlocProvider is a specialized widget used to provide a bloc. As a best practice repositories are injected into blocs and act as an abstraction layer between your data sources and your business logic component(bloc). For more details please have a look at bloc's architecture overview.

As for your error please share a github gist or repo and I'll have a look. 👍

As always, thanks @RollyPeres for taking the time to answer!
@Karatla closing this for now but feel free to comment with additional questions and I'm happy to continue the conversation 👍

As far as I am using flutter bloc, I never find a useful way of using the RepositoryProvider, because I instantiate the Repository directly in the bloc constructor. And because I use reverse dependency to abstract the Repository in bloc logic, that means the Repository will have all the required implementation for the specific bloc, and thus makes it a 1-to-1 dependency. So, a specific Repository is used for specific Bloc. That's why I have no idea when and why to use RepositoryProvider. Could you give some practical examples of it?
