1. Add this package to your pubspec.yaml:

   dependencies:

2. Run flutter pub get.
3. Import it in your Dart code:

   import 'package:persian_calendar/persian_calendar.dart';

Quick Start

Below is a minimal example showing how to embed the PersianCalendar widget in your app:

import 'package:flutter/material.dart';
import 'package:shamsi_date/shamsi_date.dart'; // or your Jalali library
import 'package:persian_calendar/persian_calendar.dart';

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Persian Calendar Example')),
      body: Center(
        child: PersianCalendar(
          initialDate: Jalali(1402, 12, 25), // Optional: Defaults to Jalali.now()
          startingDate: Jalali(1300, 1, 1), // Optional range start
          endingDate: Jalali(1405, 1, 1), // Optional range end
          onDateChanged: (selectedDate) {
            debugPrint('Selected date: $selectedDate');
          },
        ),
      ),
    );
  }
}

This immediately displays a Jalali calendar that defaults to the specified initialDate. When the user taps through the year, month, and day selections, onDateChanged will trigger with the final date.

Advanced Usage

1. Custom Height & Colors

If you need to tweak the height or change the colors:

PersianCalendar(
  height: 350.0,
  backgroundColor: Colors.grey.shade100,
  primaryColor: Colors.pink.shade200,
  secondaryColor: Colors.blue.shade200,
  textStyle: const TextStyle(fontSize: 16, color: Colors.black87),
  onDateChanged: (selectedDate) {
  // do something interesting
  },
)

2. Custom Confirm Button

By default, if no confirmButton is provided, we show an ElevatedButton labeled "تایید". To inject your own button:

PersianCalendar(
  onDateChanged: (selectedDate) {
  debugPrint('User picked: $selectedDate');
  },
  confirmButton: ElevatedButton(
  onPressed: () {
  // Close dialog or do something else
  debugPrint('User confirmed date selection');
  },
    child: const Text('Confirm'),
  ),
)

You decide how to handle the chosen date in your own UI flow.

3. Using in a Dialog

To place the PersianCalendar inside a dialog:

Future<void> _showPersianCalendarDialog(BuildContext context) async {
  return showDialog(
    context: context,
    builder: (dialogCtx) {
      return AlertDialog(
        content: PersianCalendar(
          onDateChanged: (jalaliDate) {
            debugPrint('Dialog - selected date: $jalaliDate');
          },
        ),
      );
    },
  );
}

Then call _showPersianCalendarDialog(context) from anywhere in your widget tree (e.g., a button tap).
