Fetch Default (English)

    List<Country>? countries;
    try {
      countries = await IsoCountries.iso_countries;
    } 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;
    }

  // 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(() {
      if (countries != null) {
        countryList = countries;
      }
    });
  }
  

New API Added

Passing in a country code( 2 letter) and an optional localeIdentifier( eg 'de-de', 'fr-fr'), you can get a country object with a translated name.

// Platform messages are asynchronous, so we initialize in an async method.
// IMPORTANT: Make sure the country code passed in is valid, in Android passing
// in a wrong country code, returns the country name as passed in country code not sure why.
Future<void> getCountryForCodeWithIdentifier(
    String code, String localeIdentifier) async {
  // Platform messages may fail, so we use a try/catch PlatformException.
  try {
    country = await IsoCountries.iso_country_for_code_for_locale(code,
        locale_identifier: localeIdentifier);
  } on PlatformException {
    country = 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(() {
    print(country?.name);
  });
}
