Flutter默认中文

在yaml中配置

dependencies:
  flutter_localizations:
    sdk: flutter

在入口main.dart中的MaterialApp中，加入localizationsDelegates和supportedLocales即可。
示例如下：

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
     // home: jumpTo(),你自己的widget
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: [const Locale('zh', 'CH')],
    );
  }
}
