iOS 에서 Duplicate plugin key: InAppWebViewFlutterPlugin 이슈

안녕하세요. 제가 찾고, 원했던 모듈이라 사용하려고 합니다.. 그런데 제가 flutter 에서 quill 모듈을 같이 사용하고 있는데, Duplicate plugin key: InAppWebViewFlutterPlugin 라는 메시지가 뜨면서 app이 terminating이 되어 종료됩니다.

flutter_quill와 kpostal 둘 중에 하나를 제거하면 작동을 잘합니다. 결론은 일단 InAppWebViewFlutterPlugin를 동이랗게 사용하며 key 중복으로 인해 에러가 나는 것 같은데요, 혹시 해결 방법이 있을까요?
