안녕하세요.

Unique Constraint 테스트하기 강의에서 izar database를 main 함수 내에서 여는 코드에서 에러가 나서 진행이 되지 않고 있습니다,,

main.dart

import 'package:dusty_dust/model/stat_model.dart';
import 'package:dusty_dust/screen/home_screen.dart';
import 'package:flutter/material.dart';
import 'package:isar/isar.dart';
import 'package:path_provider/path_provider.dart';

void main() async {
  //main 함수에서 runApp말고 다른 거 실행하려면 이걸 적어줘야함.
  WidgetsFlutterBinding.ensureInitialized();

  final dir = await getApplicationDocumentsDirectory();
  final isar = await Isar.open(
    [StatModelSchema],
    directory: dir.path,
  );

  runApp(
      MaterialApp(
        theme: ThemeData(
          fontFamily: 'sunflower'
        ),
        home: HomeScreen(),
  ));
}

pubspec.yaml

cupertino_icons: ^1.0.2
dio: ^5.4.3+1
isar: ^3.1.0+1
isar_flutter_libs: ^3.1.0+1
path_provider: ^2.1.2
