| 14 | +/// returned by `AppL10n.of(context)`. |
| 15 | +/// |
| 16 | +/// Applications need to include `AppL10n.delegate()` in their app's |
| 17 | +/// `localizationDelegates` list, and the locales they support in the app's |
| 18 | +/// `supportedLocales` list. For example: |
| 19 | +/// |
| 20 | +/// ```dart |
| 21 | +/// import 'gen/app_l10n.dart'; |
| 22 | +/// |
| 23 | +/// return MaterialApp( |

| 30 | +/// ## Update pubspec.yaml |
| 31 | +/// |
| 32 | +/// Please make sure to update your pubspec.yaml to include the following |
| 33 | +/// packages: |
| 34 | +/// |
| 35 | +/// ```yaml |
| 36 | +/// dependencies: |
| 37 | +/// # Internationalization support. |
| 38 | +/// flutter_localizations: |
| 39 | +/// sdk: flutter |
| 40 | +/// intl: any # Use the pinned version from flutter_localizations |
| 41 | +/// |
| 42 | +/// # Rest of dependencies |
| 43 | +/// ``` |
| 44 | +/// |
| 45 | +/// ## iOS Applications |
| 46 | +/// |
| 47 | +/// iOS applications define key application metadata, including supported |
| 48 | +/// locales, in an Info.plist file that is built into the application bundle. |
| 49 | +/// To configure the locales supported by your app, you’ll need to edit this |
| 50 | +/// file. |
| 51 | +/// |
| 52 | +/// First, open your project’s ios/Runner.xcworkspace Xcode workspace file. |
| 53 | +/// Then, in the Project Navigator, open the Info.plist file under the Runner |
| 54 | +/// project’s Runner folder. |
| 55 | +/// |
| 56 | +/// Next, select the Information Property List item, select Add Item from the |
| 57 | +/// Editor menu, then select Localizations from the pop-up menu. |
| 58 | +/// |
| 59 | +/// Select and expand the newly-created Localizations item then, for each |
| 60 | +/// locale your application supports, add a new item and select the locale |
| 61 | +/// you wish to add from the pop-up menu in the Value field. This list should |
| 62 | +/// be consistent with the languages listed in the AppL10n.supportedLocales |
| 63 | +/// property. |
