Localization in Flutter PDF Viewer (SfPdfViewer)

5 Sep 20251 minute to read

By default, the SfPdfViewer widget supports US English localization. You can change the other languages by specifying the MaterialApp properties and adding the flutter_localizations and syncfusion_localizations packages to your application.

To use flutter_localizations and syncfusion_localizations, add the packages as a dependency to the pubspec.yaml file.

  • DART
    • dependencies:
flutter_localizations:
  sdk: flutter
syncfusion_localizations: ^XX.X.XX

    Next, import the flutter_localizations and syncfusion_localizations library and specify the localizationsDelegates and supportedLocales for MaterialApp to localize the contents in the SfPdfViewer (page navigation dialog and bookmark view).

    import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:syncfusion_localizations/syncfusion_localizations.dart';

@override
Widget build(BuildContext context) {
  return MaterialApp(
    localizationsDelegates: [
      GlobalMaterialLocalizations.delegate,
      GlobalWidgetsLocalizations.delegate, 
      SfGlobalLocalizations.delegate,
    ],
    supportedLocales: [
      const Locale('fr'),
      const Locale('ru'),
      const Locale('ta'),
    ],
    locale: const Locale('fr'),
    title: 'PDF Viewer Localization',
    home: Scaffold(
      appBar: AppBar(
        title: Text('Flutter PDF Viewer'),
      ),
      body: SfPdfViewer.network(
          'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf'),
    ),
  );
}
