This example demonstrates how to get the selected dates using the selection changed callback in the Flutter Calendar.
Using the onSelectionChanged callback, you can get the selected details from the Flutter Event Calendar and display them in the Alert dialog window. When the controller's selected date changes, the onSelectionChanged callback is triggered.
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.
