TreeDataTableLocalizations class abstract

Callers can lookup localized strings with an instance of TreeDataTableLocalizations returned by TreeDataTableLocalizations.of(context).

Applications need to include TreeDataTableLocalizations.delegate() in their app's localizationDelegates list, and the locales they support in the app's supportedLocales list. For example:

import 'generated/tree_data_table_localizations.dart';

return MaterialApp(
  localizationsDelegates: TreeDataTableLocalizations.localizationsDelegates,
  supportedLocales: TreeDataTableLocalizations.supportedLocales,
  home: MyApplicationHome(),
);

Update pubspec.yaml

Please make sure to update your pubspec.yaml to include the following packages:

dependencies:
  # Internationalization support.
  flutter_localizations:
    sdk: flutter
  intl: any # Use the pinned version from flutter_localizations

  # Rest of dependencies

iOS Applications

iOS applications define key application metadata, including supported 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 file.

First, open your project’s ios/Runner.xcworkspace Xcode workspace file. Then, in the Project Navigator, open the Info.plist file under the Runner project’s Runner folder.

Next, select the Information Property List item, select Add Item from the Editor menu, then select Localizations from the pop-up menu.

Select and expand the newly-created Localizations item then, for each locale your application supports, add a new item and select the locale you wish to add from the pop-up menu in the Value field. This list should be consistent with the languages listed in the TreeDataTableLocalizations.supportedLocales property.
