+# How to add new language in Flutter date range picker (SfDateRangePicker)?
+
+In the flutter date range picker, you can change the locale of the date range picker using the `locale` property of the MaterialApp widget.
+
+## Step 1:
+For localization, you need to add the supported locales in an array. And using any one of the supported locales, you can set the locale for the date picker.
+
+```xml
+localizationsDelegates: [
+  GlobalMaterialLocalizations.delegate,
+  GlobalWidgetsLocalizations.delegate,
+],
+supportedLocales: [
+  const Locale('en'),
+  const Locale('zh'),
+  const Locale('he'),
+  const Locale('ru'),
+  const Locale('fr', 'BE'),
+  const Locale('fr', 'CA'),
+  const Locale('ja'),
+  const Locale('de'),
+  const Locale('hi'),
+  const Locale('ar'),
+],
+locale: const Locale('zh'),
+```
+ 
+
+## Step 2:
+Please find the complete code snippet for localization.
+
+```xml
+import 'package:flutter/material.dart';
+import 'package:flutter_localizations/flutter_localizations.dart';
+import 'package:syncfusion_flutter_datepicker/datepicker.dart';
+ 
+void main() => runApp(Localization());
+ 
+class Localization extends StatelessWidget {
+  // This widget is the root of your application.
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      localizationsDelegates: [
+        GlobalMaterialLocalizations.delegate,
+        GlobalWidgetsLocalizations.delegate,
+      ],
+      supportedLocales: [
+        const Locale('en'),
+        const Locale('zh'),
+        const Locale('he'),
+        const Locale('ru'),
+        const Locale('fr', 'BE'),
+        const Locale('fr', 'CA'),
+        const Locale('ja'),
+        const Locale('de'),
+        const Locale('hi'),
+        const Locale('ar'),
+      ],
+      locale: const Locale('zh'),
+      debugShowCheckedModeBanner: false,
+      home: LocalizationInPicker(),
+    );

+            icon: Icon(Icons.calendar_today),
+            itemBuilder: (BuildContext context) => views.map((String choice) {
+              return PopupMenuItem<String>(
+                value: choice,
+                child: Text(choice),
+              );
+            }).toList(),
+            onSelected: (String value) {

+              } else if (value == 'Century') {
+                _controller.view = DateRangePickerView.century;
+              }
+            },
+          ),
+        ),
+        body: Card(
+          margin: const EdgeInsets.fromLTRB(40, 150, 40, 150),
+          child: SfDateRangePicker(
