feat: ability to override a bloc/cubit/repository in the tree.

[YazeedAlKhalaf]

Description

It is frustrating that I have to split code to multiple parts to get around the fact that I can't just override a bloc provider.
Sometimes in testing, it makes that testing task a nightmare and the code untestable.

I think this is one missing feature that will make the life of a lot of developers including me, you and everybody easier.

Desired Solution

A BlocOverrides/RepositoryOverrides widget that overrides any Bloc/Repository in the tree under it. Something similar to how ProviderScope works.

Alternatives Considered

I tried splitting the providing code to a separate widget and the ui code in a different widget but that does not work for example when testing a bottom sheet opening from another screen since i use the widget that has bloc provider.

Hi @YazeedAlKhalaf 👋
Thanks for opening an issue!

BlocProvider and RepositoryProvider rely on package:provider. This sounds like a feature request for package:provider and I highly recommend moving this issue to the provider GitHub repository. Let me know what you think, thanks!

why don't we migrate to riverpod in a breaking version?

See #2100.

Closing for now since there are no actionable next steps on the bloc repo here.
