Fetch Default (English)

    } on PlatformException {
      countries = null;
    }

Fetch based on Language

    List<Country> countries;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      // If you need country names in a specific language please pass language code sample
      // fr-fr, en-en, de-de... IMPORTANT: In Android there seem to be some issue with case
      // so passing fr-FR wont work
      countries = await IsoCountries.iso_countries_for_locale("fr-fr");
    } on PlatformException {
      countries = null;
    }
    

Usage in Widget as function

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> prepareDefaultCountries() async {
    List<Country> countries;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      countries = await IsoCountries.iso_countries;
    } on PlatformException {
      countries = null;
    }
    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      countryList = countries;
    });
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> prepareLocaleSpecificCountries() async {
    List<Country> countries;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      // If you need country names in a specific language please pass language code sample
      // fr-fr, en-en, de-de... IMPORTANT: In Android there seem to be some issue with case
      // so passing fr-FR wont work
      countries = await IsoCountries.iso_countries_for_locale("fr-fr");
    } on PlatformException {
      countries = null;
    }
    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      countryList = countries;
    });
  }
