[Flutter] table_calendar에 intl 적용

https://pub.dev/packages/table_calendar

1. pubspec.yaml 추가

2. main.dart 설정

• package import
• WidgetsFlutterBinding.ensureInitialized() 추가
• async, await await initializeDateFormatting() 추가

import 'package:intl/date_symbol_data_local.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await initializeDateFormatting();

  runApp(MaterialApp(    
    home: HomeScreen(),
  ));
}

3. TableCalendar Widget 변경

• locale 추가

return TableCalendar(
      locale: 'ko_KR',
      ...

2번 과정 빠트리고 동작이 안된다고 하는 경우 있음
