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

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.isoCountries;
} 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;

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.isoCountryForCodeForLocale(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);
});
