Inheritance on Notifier with code generation

[logic-and-math]

Starting a new project and trying v2 for the first time.
Previously a lot of my code relied on state notifier inheritance.

abstract class PaginatedNotifier<T> extends StateNotifier<PaginatedState<T>> {
//code of the abstract class
}

class CarsNotifier extends PaginatedNotifier<Car> {
//code ...
} 

This allowed me to keep the common logic related to pagination in a single abstract notifier.

Now I have this notifier:

@Riverpod()
class CarNotifier extends _$CarNotifier {
  @override
  PaginatedState build(String config) {
    return PaginatedState();
  }
}

How can I do the same in v2 with code generation? Thank you

Anyone done this with Notifier without code gen?
