Factory providers

[subzero911]

Seems like there's currently no possibility to make a provider which returns a new instance every time I access it.

I can do it in get_it:

getIt.registerFactory<MyModel>(() => MyModel());

How about adding it to provider?
It either could be a new FactoryProvider, or a factory: true property to the existing Provider widget.

What's the purpose?

It might be useful for testing sometimes, like you cannot test if you just spawn RefreshUsecase() in a code.
But you can do it if you registered a factory getIt.registerFactory<RefreshUsecase>(() => MockRefreshUsecase()); and get it through getIt<RefreshUsecase>()

I don't think that's quite in the scope of what Riverpod tries to do.
It's a caching package. It feels odd to have a feature where the whole point is to not do caching.
