모달창이 안뜹니다.

강사님~ 처음부터 차근차근 다시 했는데 같은곳에서 같은 에러가 생겼습니다. 도저히 뭐를 잘못했는지 모르겠습니다.https://github.com/cloud5k/test111 레포지토리 이렇게 올리면 되는건가요?

모달창이 안뜹니다.

터미널 창에 flutter pub run build_runner build 실행하고 앱삭제 후에 다시 실행해봤습니다 그래도 같은 현상입니다. ㅜㅜimport 'package:calendar_scheduler/model/category_color.dart'; import 'package:calendar_scheduler/database/drift_database.dart';이거 2개가 비활성처럼 보이는데 혹시 이것 때문일까요?

모달창이 안뜹니다.

삭제후 재설치하고(사진)이 버튼 눌렀는데 이거 말고 다른걸 해야 하는건가요?

모달창이 안뜹니다.

에뮬레이터 다시 설치 했는데도 똑같습니다~ ㅜㅜ 에러 메시지 입니다~======== Exception caught by widgets library =======================================================The following CastError was thrown building FutureBuilder>(dirty, state: FutureBuilderState>#f31e4):Null check operator used on a null valueThe relevant error-causing widget was:FutureBuilder> FutureBuilder:file:///D:/app/calendar_scheduler/lib/component/schedule_bottom_sheet.dart:60:21When the exception was thrown, this was the stack:#0 ScheduleBottomSheetState.build.
