A quick-start example to help you to customize the month cell based on the appointment using builder in the Flutter Calendar.
Using the monthCellBuilder property of the calendar, you can customise the month cell based on appointments in the Flutter Event Calendar.
For cell customization, you can use the required widget. The Text widget was used to customise the month cell in this example. MonthCellDetails returns information about the cell (date, appointments, visibleDates, bounds). You can use this to obtain the cell's appointment details.
To run this application, you need to first clone or download the ‘create a flutter maps widget in 10 minutes’ repository and open it in your preferred IDE. Then, build and run your project to view the output.
