+/// Callers can lookup localized strings with an instance of AppLocale

+/// Applications need to include `AppLocale.delegate()` in their app's
+/// `localizationDelegates` list, and the locales they support in the app's

+/// ```dart

+/// ## Update pubspec.yaml
+///
+/// Please make sure to update your pubspec.yaml to include the following

+///   # Internationalization support.

+/// locales, in an Info.plist file that is built into the application bundle.
+/// To configure the locales supported by your app, you’ll need to edit this

+/// project’s Runner folder.
