This is probably simple for anyone who knows basic state management. I may not have to be familiar with Syncfusion Flutter Calendar to know this.
I basically want the user to add their own appointments to the calendar. In this case to the dataSource (DataSource / CalendarDataSource) -all appointments are "all day" - the user chooses only the day.
Please go to my git and look into the code since stackoverflow wont allow too much code. I simplified the app to keep it short. Please use VCS and try it in a simulator/emulator
Thank you!
