I need to display an Arabic date picker , I can't control this with Locale constructor . It's only display an English view .

Pick date metod

  DateTime selectedDate = DateTime.now();

  Future<void> _selectDate(BuildContext context) async {
    final DateTime picked = await showDatePicker(
        context: context,
        initialDate: selectedDate,
        firstDate: DateTime(2000, 1),
        lastDate: DateTime(2100),
        builder: (BuildContext context, Widget child) {
          return Theme(
            data: Theme.of(context).copyWith(
                colorScheme: ColorScheme.light(primary: primaryColor)),
            child: child,
          );
        });

    if (picked != null && picked != selectedDate) {
      selectedDate = picked;
    }
  }

Main Screen

void main() async {
      WidgetsFlutterBinding.ensureInitialized();
      await GetStorage.init();
      runApp(
        MyApp(),
      );
    }

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      debugShowCheckedModeBanner: false,
      translations: Translation(),
      locale: Locale(AuthController().appLocal.value),
      fallbackLocale: Locale(AuthController().appLocal.value),
      title: 'Hesabate App',
      theme: ThemeData(
        canvasColor: Colors.transparent,
        fontFamily: "NotoNaskhArabic_font",
      ),
      initialRoute: AppRoutes.splashScreen,
      getPages: AppRoutes.routes,
    );
  }
}

I have an updated language(en&ar) at this variable

AuthController().appLocal.value

CodePudding user response：

Can you be more specific on which package you are using?. For example flutter_datetime_picker have parameter locale, where you can pass LocalType.ar

  static Future<DateTime?> showPicker(
BuildContext context, {
bool showTitleActions: true,
DateChangedCallback? onChanged,
DateChangedCallback? onConfirm,
DateCancelledCallback? onCancel,
locale: LocaleType.en,
BasePickerModel? pickerModel,
DatePickerTheme? theme,

Edited per Nader clarification, you can pass locale:Locale("ar") to the internal date_picker

  const Locale(
this._languageCode, [
this._countryCode, ])

thank you , I found the solution I was looking for . to solve the Issue , I did some steps :

In order to show the date picker in local language, you need to make use of flutter_localizations plugin and specify localizationDelegates and supportedLocales inside MaterialApp in your main code

1.Add flutter_localizations plugin in pubspec.yaml and run pub get.

flutter_localizations:
        sdk: flutter

2.Import the plugin in dart file

import 'package:flutter_localizations/flutter_localizations.dart';

3.Inside MaterialApp, add following

  return GetMaterialApp(
       localizationsDelegates: [
         GlobalMaterialLocalizations.delegate
       ],
       supportedLocales: [
         const Locale('en'),
         const Locale('ar')
       ],

4.then implement default datePicker as following

 DateTime selectedDate = DateTime.now();

  Future<void> _selectDate(BuildContext context) async {
    final DateTime picked = await showDatePicker(
        context: context,
        initialDate: selectedDate,
        firstDate: DateTime(2000, 1),
        lastDate: DateTime(2100),
        builder: (BuildContext context, Widget child) {
          return Theme(
            data: Theme.of(context).copyWith(
                colorScheme: ColorScheme.light(primary: primaryColor)),
            child: child,
          );
        });

    if (picked != null && picked != selectedDate) {
      selectedDate = picked;
    }
  }

5.finally call the previous method into your date TextField as following

Expanded(
       child: CustomTextField(
         hint: "date".tr,
         onPress: () => _selectDate(context),
        ),
