      title: 'Date and Time Pickers',
      locale: const Locale("fa", "IR"),
      supportedLocales: const [
        Locale("fa", "IR"),
        Locale("en", "US"),
      ],
      localizationsDelegates: const [
        // Add Localization
        PersianMaterialLocalizations.delegate,
        PersianCupertinoLocalizations.delegate,
        //
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
      ],
      ...
    );

️ Usage Examples

1. Persian Date Picker

Jalali picked = await showPersianDatePicker(
  context: context,
  initialDate: Jalali.now(),
  firstDate: Jalali(1385, 8),
  lastDate: Jalali(1450, 9),
);
var label = picked.formatFullDate();

2. Persian Time Picker

var picked = await showTimePicker(
  context: context,
  initialTime: TimeOfDay.now(),
);
var label = picked.persianFormat(context);

3. Modal Bottom Sheet with Persian Date Picker

Jalali pickedDate = await showModalBottomSheet<Jalali>(
  context: context,
  builder: (context) {
    Jalali tempPickedDate;
    return Container(
      height: 250,
      child: Column(
        children: [
          Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [
              CupertinoButton(
                child: Text('لغو', style: TextStyle(fontFamily: 'Dana')),
                onPressed: () => Navigator.of(context).pop(),
              ),
              CupertinoButton(
                child: Text('تایید', style: TextStyle(fontFamily: 'Dana')),
                onPressed: () => Navigator.of(context).pop(tempPickedDate ?? Jalali.now()),
              ),
            ],
          ),
          Divider(height: 0, thickness: 1),
          Expanded(
            child: CupertinoTheme(
              data: CupertinoThemeData(
                textTheme: CupertinoTextThemeData(dateTimePickerTextStyle: TextStyle(fontFamily: "Dana")),
              ),
              child: PCupertinoDatePicker(
                mode: PCupertinoDatePickerMode.dateAndTime,
                onDateTimeChanged: (Jalali dateTime) {
                  tempPickedDate = dateTime;
                },
              ),
            ),
          ),
        ],
      ),
    );
  },
);

4. Persian Date Range Picker

var picked = await showPersianDateRangePicker(
  context: context,
  initialEntryMode: PDatePickerEntryMode.input,
  initialDateRange: JalaliRange(
    start: Jalali(1400, 1, 2),
    end: Jalali(1400, 1, 10),
  ),
  firstDate: Jalali(1385, 8),
  lastDate: Jalali(1450, 9),
);

5. Customizing Date Picker Styles

You can customize the styles of the PersianDateTimePicker and PersianCupertinoDatePicker using the DatePickerTheme within your app's ThemeData. Additionally, you can apply specific styles by wrapping the date picker with Theme in the builder.

Example for Persian Date Picker

Add the DatePickerTheme to your ThemeData:

return MaterialApp(
  theme: ThemeData(
    // Other theme properties...
    datePickerTheme: DatePickerTheme(
      backgroundColor: Colors.white, // Background color of the date picker
      primaryColor: Colors.teal, // Primary color for the date picker
      textColor: Colors.black, // Text color
      // Customize more properties as needed
    ),
  ),
  // ...
);

Customizing Persian Date Picker with Theme in Builder

You can also customize the Persian date picker on a per-instance basis by wrapping it with a Theme in the builder:

Jalali? picked = await showPersianDatePicker(
  context: context,
  initialDate: Jalali.now(),
  firstDate: Jalali(1385, 8),
  lastDate: Jalali(1450, 9),
  builder: (context, child) {
    return Theme(
      data: Theme.of(context).copyWith(
        primaryColor: Colors.teal, // Override primary color
        accentColor: Colors.amber, // Override accent color
        // Add more customization here
      ),
      child: child!,
    );
  },
);

Example for Persian Cupertino Date Picker

To customize the PersianCupertinoDatePicker, you can similarly apply a Theme:

showCupertinoModalPopup(
  context: context,
  builder: (context) {
    return Theme(
      data: Theme.of(context).copyWith(
        primaryColor: Colors.teal, // Override primary color
        // Add more customization here
      ),
      child: Container(
        height: 300,
        child: PersianCupertinoDatePicker(
          mode: PersianCupertinoDatePickerMode.dateAndTime,
          onDateTimeChanged: (Jalali dateTime) {
            // Handle date change
          },
        ),
      ),
    );
  },
);

6. Using Material 2 Instead of Material 3

If you prefer to use Material 2 instead of Material 3 for your application, you can do so by setting the useMaterial3 parameter to false in the MaterialApp widget. This ensures that the application uses the Material 2 design principles.

Example

Here’s how to set up your MaterialApp to use Material 2:

return MaterialApp(
  title: 'Persian DateTime Picker',
  theme: ThemeData(
    useMaterial3: false, // Set to false to use Material 2
    datePickerTheme: DatePickerTheme(
      backgroundColor: Colors.white,
      primaryColor: Colors.teal,
      textColor: Colors.black,
      // Additional customizations
    ),
  ),
  home: MyHomePage(),
);
