initializeMessages function Null safety
- String localeName
User programs should call this before using localeName
for messages.
Implementation
Future<bool> initializeMessages(String localeName) {
var availableLocale = Intl.verifiedLocale(
localeName, (locale) => _deferredLibraries[locale] != null,
onFailure: (_) => null);
if (availableLocale == null) {
return new SynchronousFuture(false);
}
var lib = _deferredLibraries[availableLocale];
lib == null ? new SynchronousFuture(false) : lib();
initializeInternalMessageLookup(() => new CompositeMessageLookup());
messageLookup.addLocale(availableLocale, _findGeneratedMessagesFor);
return new SynchronousFuture(true);
}
