I trying to do localization in flutter. Can you help me with this problem. How to do a localization in flutter? Come on, I need to create localization in flutter. AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAa

  final connectivity = Connectivity();
  late StreamSubscription<List<ConnectivityResult>> connRes;
  final FlutterLocalization localization = FlutterLocalization.instance;


  @override
  void initState() {
    WidgetsBinding.instance.addObserver(this);
    // ru_RU -> ru
    final String localeName = Platform.localeName.split("_").first;
    localization.init(
      mapLocales: [
        const MapLocale('en', AppLocale.EN),
        const MapLocale('ru', AppLocale.RU),
      ],
      initLanguageCode: (localeName != "ru") ? "en" : "ru",
    );
    localization.onTranslatedLanguage = (_) => setState(() {});
    super.initState();

    connRes = connectivity.onConnectivityChanged.listen((event) {
      if (event.first == ConnectivityResult.none){
        showError(context, 'Internet crached');
      }
    });
  }

  @override
  void didChangeLocales(List<Locale>? locales) {
    if (locales == null){
      return;
    }
    localization.translate((locales.first.languageCode != "ru")
      ? "en"
      : "ru"
    );
    super.didChangeLocales(locales);
  }

  @override
  void dispose() {
    WidgetsBinding.instance.removeObserver(this);
    super.dispose();
    connRes.cancel();
  }
