Accessing previous state within StateProvider.

[TreyThomas93]

I was wondering if there was a way to access the previous state when calling a StateProvider. I attempt to use ref.controller.state, but I end up with a The type of 'StateProvider' cannot be inferred because it depends on itself through the cycle: [StateProvider] error.

The error sounds like you didn't specify the generic type for your provider.

Do:

final provider = STateProvider<T>(...);

not:

final provider = STateProvider(...);

@rrousselGit I did add a type to the StateProvider:

StateProvider<List<Note>>
