load method
Start loading the resources for locale
. The returned future completes
when the resources have finished loading.
It's assumed that this method will return an object that contains a collection of related string resources (typically defined with one method per resource). The object will be retrieved with Localizations.of.
Implementation
@override
Future<L10n> load([Locale? locale]) {
L10n.locale = locale;
return SynchronousFuture<L10n>(this);
}
