Answer 1

hello i solved the problem. The problem was giving an error because there were 2 classes with the same name, so my StatefulWidget class name was the same as my block state class name :) It was fixed when I changed the name of my block state class.

Answer 2

您可以对 StatefulWidget 状态使用相同的名称，并在块或状态中再次使用该名称请不要重复相同的名称，这就是错误来的原因

Answer 3

this happens when

1. You have two classes with the same name
2. You add the bloc instead of the event

ex:

class CounterBloc extends Bloc<CounterBloc, CounterState> {
  CounterBloc() : super(const InitialState()) {
    on<IncrementEvent>((event, emit) {
      emit(IncrementedCounterState());
    });
    on<IncrementEvent>((event, emit) {
      emit(DecrementedCounterState());
    });
  }
}

I should pass the Event not the bloc in the Bloc<CounterBloc,CounterState> and it should be Bloc<CounterEvent,CounterState>

3. I will update it with more.
