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

+/// Applications need to include `AppLocalizations.delegate()` in their app's

+/// Editor menu, then select Localizations from the pop-up menu.

+/// Select and expand the newly-created Localizations item then, for each
