Flutter 颤振：应用'；并非其所有本地化代理都支持s区域设置

您好，我正在尝试在Flatter应用程序中添加BottomNavigationBar，但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理：

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

这是自定义本地化数据包：

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;
}

class CLocalizationsDelegate
扩展本地化数据包{
const CLocalizationsDelegate（）；
@凌驾
bool isSupported（区域设置）=>
['en'，'ka'，'ru'].contains（locale.languageCode）；
@凌驾
未来加载（区域设置）异步{
CLocalizations localizations=新的CLocalizations（locale）；
等待本地化。加载（）；
打印（“加载${locale.languageCode}”）；
回归局部化；
}
@凌驾
bool应该重新加载（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，所以各位可以帮我解决吗？

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
}

class MaterialLocalizationKaDelegate扩展本地化Delegate{
@凌驾
bool isSupported（区域设置）{
返回locale.countryCode==“GE”&&locale.languageCode==“ka”；
}
@凌驾
未来加载（区域设置）异步{
返回MaterialLocalizationKa（）；
}
@凌驾
bool应重新加载（Foo old）{
返回false；
}
}
类MaterialLocalization扩展了MaterialLocalization{
//TODO:自己实现KA本地化
}

您必须为

ka
