Question

아래 화면을 구현했습니다. 그런데 재시작을 할 때마다, 아래와 같은 오류가 뜹니다. ======== Exception caught by widgets library ======================================================= The following assertion was thrown while finalizing the widget tree: _PaginationListViewState.dispose failed to call super.dispose. dispose() implementations must always call their superclass dispose() method, to ensure that all the resources used by the widget are fully released.

안녕하세요! 에러 메세지를 보니 아마 dispose() 함수를 선언하면서 super.dispose() 함수 실행을 깜빡 하신 것 같습니다. 초급 라이프 사이클 강의에서 알려드린 것 처럼 dispose() 함수를 오버라이드 할 경우 꼭 super.dispose()를 실행 해주셔야합니다. 감사합니다!
