BehaviorSubject close 이슈 Bad state: Cannot add new events after calling close

Bad state: Cannot add new events after calling close 관련

 

 

 

BehaviorSubject close 하면 객체가 폐기된다.

그래서 다음에 또 사용하려면 이벤트 추가를 할수가없음

 

그래서 참조값을 late 로 선언만 해놓고

사용하는 페이지에서 초기화해주고, dispose에서 close해주는게 좋다.

 

class MyBloc {
  final _data = BehaviorSubject<String>();
  
  void fetchData() {
    // get your data from wherever it is located
    _data.safeValue = 'Safe to add data';
  }

  void dispose() {
    _data.close();
  }
}

 

 

-> MyBloc 사용할때 초기화되고, 페이지 떠나면 close, 다시 사용할때 초기화되고, 페이지 떠나면 close
