Flutter：应用程序的区域设置不受其所有本地化代表的支持

您好，我正在尝试在 flutter 应用程序中添加 BottomNavigationBar 但当我运行项目时出现错误：

A MaterialLocalizations delegate that supports the ka_GE locale was not found

这是我的应用程序代表：

  supportedLocales: [
    const Locale('en', 'US'),
    const Locale('ka', 'GE'),
    const Locale('ru', 'RU'),
  ],
  localizationsDelegates: [
    const InfosLocalizationsDelegate(),
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate
  ],
  locale: Locale('ka')

这是自定义本地化委托：

class CLocalizationsDelegate
    extends LocalizationsDelegate<CLocalizations> {
  const CLocalizationsDelegate();

  @override
  bool isSupported(Locale locale) =>
      ['en', 'ka', 'ru'].contains(locale.languageCode);

  @override
  Future<CLocalizations> load(Locale locale) async {
    CLocalizations localizations = new CLocalizations(locale);
    await localizations.load();
    print("Load ${locale.languageCode}");
    return localizations;
  }

  @override
  bool shouldReload(CLocalizationsDelegate old) => false;
}

是的，我知道问题是“ka”，因为 MaterialLocalizations 不支持它，但我必须解决这个问题，所以你们能帮我吗？

Addig 全球库比蒂诺本地化本地化代表也解决了这个问题。

return MaterialApp(
  localizationsDelegates: const [
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
    GlobalCupertinoLocalizations.delegate,
  ],
  // ...
);
