问在不使用MaterialApp的情况下将本地化添加到小工具？

EN

class WidgetToTest extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    //AppLocalizations.of(context)!.hello = 'hello' in generated file
    return Text(AppLocalizations.of(context)!.hello);
  }
}

  testWidgets('test localizations widget', (tester) async {
    await tester.pumpWidget(
      Localizations(
        locale: const Locale('en'),
        delegates: AppLocalizations.localizationsDelegates,
        child: WidgetToTest(),
      )
    );
    expect(find.text('hello'), findsOneWidget);
  });
