[Flutter] riverpod consumerstateful widget에서 param 받기

문제

제목이 참 길다.
이번에 발생한 문제는

class VideoPreview extends ConsumerStatefulWidget {
  final File video;

  const VideoPreview({Key? key, required this.video}) : super(key: key);

  @override
  VideoPreviewState createState() => VideoPreviewState();
}

class VideoPreviewState extends ConsumerState{
  Trimmer trimmer = Trimmer();
  bool trimmerLoaded = false;
  @override
  void initState() {
    trimmer.loadVideo(videoFile: widget.video); // error
  }
}

ConsumerState에서 param으로 받아온 video에 접근할 수 없는 문제였다.

해결

class VideoPreview extends ConsumerStatefulWidget {
  final File video;

  const VideoPreview({Key? key, required this.video}) : super(key: key);

  @override
  VideoPreviewState createState() => VideoPreviewState();
}

class VideoPreviewState extends ConsumerState<VideoPreview>{
  Trimmer trimmer = Trimmer();
  bool trimmerLoaded = false;
  @override
  void initState() {
    trimmer.loadVideo(videoFile: widget.video);
  }
}

ConsumerState<T extends ConsumerStatefulWidget>로 고쳐주면 해결...
