How to localize the Text in the filter popup menu and customize the popup menu options in a Flutter DataTable (SfDataGrid)?

In this article, we will guide you through the process of localizing the text in the filter popup menu of a Flutter DataGrid and customizing the available options.

STEP 1:

You need to add the following package in the dependencies of pubspec.yaml.

syncfusion_localizations: ^21.2.5
flutter_localizations:
    sdk: flutter

STEP 2:

Import the following library into the flutter application:

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

STEP 3:

Ensure that the localizationsDelegates property in the MaterialApp widget contains the required localizations. Declare the supported locales in the supportedLocales property and assign the desired locale to the locale property.

class MyApp extends StatelessWidget {
 const MyApp({super.key});

 @override
 Widget build(BuildContext context) {
   return MaterialApp(
     localizationsDelegates: const [
       GlobalMaterialLocalizations.delegate,
       GlobalWidgetsLocalizations.delegate,
       SfGlobalLocalizations.delegate
     ],
     supportedLocales: const [
       Locale('zh'),
       Locale('ar'),
       Locale('ja'),
     ],
     locale: const Locale('ar'),
     title: 'Syncfusion DataGrid Demo',
     theme: ThemeData(primarySwatch: Colors.blue),
     home: MyHomePage(),
   );
 }
}
