在不使用MaterialApp的情况下将本地化添加到小工具？

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter
  intl: ^0.17.0

import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:intl/intl.dart';
import 'package:intl/date_symbol_data_local.dart';

void main() {
  initializeDateFormatting().then((_) {
    runApp(MyApp());
  });
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: [
        const Locale('en', 'US'),
        const Locale('zh', 'CN'),
      ],
      home: MyWidget(),
    );
  }
}

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var dateTime = DateTime.now();
    var formattedDate = DateFormat.yMMMMd('en_US').format(dateTime);
    
    return Text(formattedDate);
  }
}
