Appointment disappears when navigating to another page

[numa rai]

I have implemented a SfCalendar in my flutter app. I can add, edit and remove appointments but I noticed that when I go to another page and come back to the SfCalendar, whatever appointments that were added are no longer there. I feel like it has something to do with the done button for which the code is :

IconButton(

padding: const EdgeInsets.fromLTRB(5, 0, 5, 0),

icon: const Icon(

Icons.done,

color: Colors.white,

),

onPressed: () {

final List<Events> events = <Events>[];

if (_selectedAppointment != null) {

_events.appointments!.removeAt(

_events.appointments!.indexOf(_selectedAppointment));

_events.notifyListeners(CalendarDataSourceAction.remove,

<Events>[]..add(_selectedAppointment!));

}

events.add(Events(

from: _startDate,

to: _endDate,

background: _colorCollection[_selectedColorIndex],

description: _notes,

isAllDay: _isAllDay,

eventName: _subject == '' ? '(No title)' : _subject,

));

_events.appointments!.add(events[0]);

_events.notifyListeners(CalendarDataSourceAction.add, events);

_selectedAppointment = null;

Navigator.pop(context);

})

How do I save appointments?
