getLocalization method
Gets the current localization code used by the plugin for notification content.
This method returns a Future that resolves to a String
representing
the current localization code. The localization code is a two-letter language
code (e.g. "en" for English, "pt" for Portuguese) or a language code combined
with a region code (e.g. "pt-br" for Brazilian Portuguese). If no localization
has been set, this method will return the system's default language code.
Implementation
@override
Future<String> getLocalization() async {
return AwesomeNotificationsPlatform.instance.getLocalization();
}
