Are you ready to elevate your Flutter app with a delightful calendar feature? The flutter_calendar_carousel package provides a robust solution to incorporate a highly customizable calendar. Whether you want a sleek design, the ability to swipe between months, or even mark special events with unique icons, this package has got you covered! Let’s dive into the steps to set it up effectively.

Getting Started

Before we proceed, make sure you have Flutter installed and set up. You can view the online documentation for more detailed installation instructions if needed.

Step 1: Add Dependency

First, add flutter_calendar_carousel to your pubspec.yaml file:

dependencies:
  flutter_calendar_carousel: ^2.0.3

Now, save the file and run flutter pub get to install the package.

Step 2: Import the Package

In your Dart file, you’ll need to import the Calendar Carousel:

import 'package:flutter_calendar_carousel/flutter_calendar_carousel.dart';

Step 3: Create the Calendar Widget

Now let’s create a widget for your calendar. Think of your calendar as a beautifully designed book where each page displays a unique date with the potential for events:

Widget build(BuildContext context) {
  return Container(
    margin: EdgeInsets.symmetric(horizontal: 16.0),
    child: CalendarCarousel(
      onDayPressed: (DateTime date, List events) {
        setState(() {
          _currentDate = date; // Update the current date based on user selection
        });
      },
      weekendTextStyle: TextStyle(color: Colors.red),
      thisMonthDayBorderColor: Colors.grey,
      headerText: Container(
        child: Text('Custom Header'), // Custom Header
      ),
      customDayBuilder: (bool isSelectable, int index, bool isSelectedDay, bool isToday, bool isPrevMonthDay, TextStyle textStyle, bool isNextMonthDay, bool isThisMonthDay, DateTime day) {
        // Customize how each day is displayed
        if (day.day == 15) {
          return Center(child: Icon(Icons.local_airport)); // Highlight the 15th with an icon
        } else {
          return null; // Use default display for other days
        }
      },
      height: 420.0,
      selectedDateTime: _currentDate,
      daysHaveCircularBorder: false, // Border style
    ),
  );
}

In the code snippet above, we created a calendar that updates the current date when a user taps on it. We also customized it to show an icon on the 15th of each month.

Step 4: Customize Your Calendar

The calendar offers several props for customization:

• viewPortFraction: Determines visible pages while swiping.
• markedDatesMap: Great for marking important dates.
• dayPadding: Adjusts spacing between days.
• headerTextStyle: Customize the style of the header text.

You can mix and match these props to tailor the calendar’s appearance to fit your app’s theme.

Troubleshooting Tips

If you encounter any issues while implementing the calendar, here are some troubleshooting tips:

• Ensure you have the correct version of Flutter. This widget is compatible with Flutter v3 and above, starting from version 2.4.+.
• Double-check your pubspec.yaml file to ensure the package is added correctly.
• Restart your Flutter app after making changes to see them reflected.
• Check for any typos in your Dart code, as these are often the culprits of common errors.
