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<TimetableLocalizations> load(Locale locale) {
assert(isSupported(locale));
if (setIntlLocale) Intl.defaultLocale = locale.toLanguageTag();
var localizations = _getLocalization(locale);
if (fallbackLocale != null) {
localizations ??= _getLocalization(fallbackLocale!)!;
}
return SynchronousFuture(localizations!);
}
