_App 클래스가 ConsumerWidget을 상속 받으면 에러가 생깁니다
미해결
[코드팩토리] [중급] Flutter 진짜 실전! 상태관리, 캐시관리, Code Generation, GoRouter, 인증로직 등 중수가 되기 위한 필수 스킬들!
안녕하세요, 시간이 없어 어떻게든 꾸역꾸역 듣고 있는데도 많은 도움을 얻고 있습니다. _App 클래스에서 MaterialApp 위젯을 .router 생성자로 부르고 _App 클래스가 ConsumerWidget를 상속 받게끔 코드를 고치니 에러가 발생합니다. 가장 위에 보이는 에러는 이렇습니다. 다시 ConsumerWidget에서 StatelessWidget을 상속 받게 하니 에러는 발생하지 않습니다. .router 생성자를 빼도 에러가 발생하는 것을 보아 리버팟과 관련된 이슈인 듯 합니다. 저는 강의가 나온 후 조금 지난 시점에 듣기 시작해서 이미 리버팟이 2.1.대 버전일 때 시작했는데 강의와 시차가 있어 발생하는 문제일까요? 강사님 아니더라도 해결하신 분이 있다면 조언 부탁드립니다. 감사합니다. 에러 메시지 및 스택은 다음과 같습니다.
