rtc api 오류 해결 부탁드려여~~

처음부터 끝까지 그대로 따라쳤는데

Widget renderSubView(){
  if(otherUid == null){
    return Center(
      child: Text('채널에 유저가 없습니다.'),
    );
  }else{
    return RtcRemoteView.SurfaceView(
      uid: otherUid!,
      channelId: CHANNEL_NAME,
    );
  }
}

이부분을 넣을 때부터 에러 메시지가 나옵니다.

코드의 오류가 있는지 확인해보려고 강사님 깃허브를 통째로 복사해서 돌려보았는데도 똑같이 에러가 나네요 ㅠㅠ

구글을 검색해도 어떤 에러인지 알수가 없는데 대략 어떤부분을 봐야할지 알려주시면 감사하겠습니다.
