你好，我正在尝试添加BottomNavigationBar在Flutter应用程序，但当我运行项目错误occures：

A MaterialLocalizations delegate that supports the ka_GE locale was not found

字符串
这是我的APP委托：

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

型
这是Custom LocalizationsDelegate：

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;
}

型
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，所以伙计们，你们能帮我吗？

添加 * GlobalCupertino Localizations * 到localizationsDelegates也可以解决问题。

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

您可以实现自定义MaterialLocalizations委托

class MaterialLocalizationKaDelegate extends LocalizationsDelegate<MaterialLocalizations> {
  @override
  bool isSupported(Locale locale) {
    return locale.countryCode == "GE" && locale.languageCode == "ka";
  }

  @override
  Future<MaterialLocalizations> load(Locale locale) async {
    return MaterialLocalizationKa();
  }

  @override
  bool shouldReload(Foo old) {
    return false;
  }
}

class MaterialLocalizationKa extends MaterialLocalizations {
  // TODO: implement KA localization yourself
}
