  firstDate: Jalali(1385, 8),
  lastDate: Jalali(1450, 9),
  initialEntryMode:
      PersianDatePickerEntryMode.calendarOnly,
  initialDatePickerMode: PersianDatePickerMode.year,
);
var label = picked.formatFullDate();

2. Persian Time Picker

            .copyWith(alwaysUse24HourFormat: true),
        child: child!,
      ),
    );
  },
);
if (picked != null) String label = picked.toString();

3. Modal Bottom Sheet with Persian Cupertino Date Picker

Jalali? pickedDate = await showModalBottomSheet<Jalali>(
  context: context,
  builder: (context) {
    Jalali? tempPickedDate;
    return Container(
      height: 250,
      child: Column(
        children: <Widget>[
          Container(
            child: Row(
              mainAxisAlignment:
                  MainAxisAlignment.spaceBetween,
              children: <Widget>[
                CupertinoButton(
                  child: Text(
                    'لغو',
                    style: TextStyle(
                      fontFamily: 'Dana',
                    ),
                  ),
                  onPressed: () {
                    Navigator.of(context).pop();
                  },
                ),
                CupertinoButton(
                  child: Text(
                    'تایید',
                    style: TextStyle(
                      fontFamily: 'Dana',
                    ),
                  ),
                  onPressed: () {
                    print(
                        tempPickedDate ?? Jal
                    Navigator.of(context).pop(
                        tempPickedDate ?? Jalali.now());
                  },
                ),
              ],
            ),
          ),
          Divider(
            height: 0,
            thickness: 1,
          ),
          Expanded(
            child: Container(
              child: PersianCupertinoDatePicker(
                initialDateTime: Jalali.now(),
                mode:
                    PersianCupertinoDatePickerMode.time,
                onDateTimeChanged: (Jalali dateTime) {
                  tempPickedDate = dateTime;
                },
              ),
            ),
          ),
        ],
      ),
    );
  },

if (pickedDate != null) {
   String label = '${pickedDate.toJalaliDateTime()}';
}

4. Persian Date Range Picker

var picked = await showPersianDateRangePicker(
  context: context,
  initialDateRange: JalaliRange(
    start: Jalali(1400, 1, 2),
    end: Jalali(1400, 1, 10),
  ),
  firstDate: Jalali(1385, 8),
  lastDate: Jalali(1450, 9),
  initialDate: Jalali.now(),
);
String  label =
      "${picked?.start?.toJalaliDateTime() ?? ""} ${picked?.end?.toJalaliDateTime() ?? ""}";

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 CupertinoTheme:

showCupertinoModalPopup(
  context: context,
  builder: (context) {
    return CupertinoTheme(
      data: CupertinoThemeData(
        textTheme: CupertinoTextThemeData(
          dateTimePickerTextStyle: TextStyle(color: Colors.white),
        ),
        // Add more customization here
      ),
      child: Container(
        height: 300,
        child: PersianCupertinoDatePicker(
          mode: PersianCupertinoDatePickerMode.dateAndTime,
          onDateTimeChanged: (Jalali dateTime) {
            // Handle date change
          },
        ),
      ),
    );
  },
);

Customization Note

All customization options for the PersianDateTimePicker and PersianCupertinoDatePicker are similar to those of the native Flutter date pickers. You can easily apply styles using ThemeData, DatePickerTheme, or by wrapping the pickers with Theme in the builder, just like you would with native Flutter widgets.

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(),
);
