Bloc 库状态未重建

Question

 Widget build(BuildContext context) {
return Scaffold(
  body: MultiBlocListener(
    listeners: [
      BlocListener<QuestionholderBloc, QuestionholderState>(
        listener: (context, state) {
          if (state is NoQuestions) {
            _dbbloc.add(GetQuestions());
          } else if (state is HasQuestions) {
            _statusbloc.add(GetQuestion());
          }
        },
      ),
      BlocListener<DatabaseBloc, DatabaseState>(
        listener: (context, state) {
          if (state is Loaded) {
            _statusbloc.add(SetQuestions(questionsToSet: state.questions));
          }
        },
      ),
    ],
    child: BlocBuilder<QuestionholderBloc, QuestionholderState>(
      builder: (context, state) {
        if (state is QuestionLoaded) {
          return QuestionWidget(question: state.question);
        } else {
          return CircularProgressIndicator();
        }
      },
    ),
  ),
);

} }

我在 QuestionWidget 上有一个按钮可以触发 getQuestion 事件。最初，一切正常，但按下按钮时 QuestionWidget 不会使用新值重建。

集团没有任何问题，但我一遍又一遍地提出同样的问题。现在可以了。
