강사님~ 처음부터 차근차근 다시 했는데 같은곳에서 같은 에러가 생겼습니다. 도저히 뭐를 잘못했는지 모르겠습니다. <a target="_blank" rel="noopener noreferrer nofollow" href="https://github.com/cloud5k/test111">https://github.com/cloud5k/test111</a>&nbsp;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?

삭제후 재설치하고<img src="https://cdn.inflearn.com/public/comments/f6aaa44f-7caf-49c0-ad70-bbd5c496259e/캡처.JPG" alt="image" title="image">이 버튼 눌렀는데 이거 말고 다른걸 해야 하는건가요?

에뮬레이터 다시 설치 했는데도 똑같습니다~ ㅜㅜ 에러 메시지 입니다~======== Exception caught by widgets library =======================================================The following CastError was thrown building FutureBuilder<List<CategoryColor>>(dirty, state: FutureBuilderState<List<CategoryColor>>#f31e4):Null check operator used on a null valueThe relevant error-causing widget was:FutureBuilder<List<CategoryColor>> FutureBuilder:file:///D:/app/calendar_scheduler/lib/component/schedule_bottom_sheet.dart:60:21When the exception was thrown, this was the stack:#0 <a target="_blank" rel="noopener noreferrer nofollow" href="http://ScheduleBottomSheetState.build">ScheduleBottomSheetState.build</a>.<anonymous closure> (package:calendarscheduler/component/schedule_bottom_sheet.dart:72:59)#1 _<a target="_blank" rel="noopener noreferrer nofollow" href="http://FutureBuilderState.build">FutureBuilderState.build</a> (package:flutter/src/widgets/async.dart:615:55)#2 <a target="_blank" rel="noopener noreferrer nofollow" href="http://StatefulElement.build">StatefulElement.build</a> (package:flutter/src/widgets/framework.dart:4919:27)#3 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:4806:15)#4 StatefulElement.performRebuild (package:flutter/src/widgets/framework.dart:4977:11)#5 Element.rebuild (package:flutter/src/widgets/framework.dart:4529:5)#6 ComponentElement._firstBuild (package:flutter/src/widgets/framework.dart:4787:5)#7 StatefulElement._firstBuild (package:flutter/src/widgets/framework.dart:4968:11)#8 ComponentElement.mount (package:flutter/src/widgets/framework.dart:4781:5)#9 Element.inflateWidget (package:flutter/src/widgets/framework.dart:3817:16)#10 MultiChildRenderObjectElement.inflateWidget (package:flutter/src/widgets/framework.dart:6350:36)#11 MultiChildRenderObjectElement.mount (package:flutter/src/widgets/framework.dart:6362:32)...
