[syncfusion_flutter_calendar] appointments get missing switching month in the calendar

[tonnyavery]

Platform: MacOS

Having DataSource set and monthCellBuilder configured I am checking for MonthCellDetails.appointments to decide how I want to display it on the screen. showNavigationArrow is set to true.

When changing a month in the Calendar navigation, monthCellBuilder gets called again, but appointments are empty, even though the previous call data was there. Switching 2 months behind and then 2 months ahead again I can see the appointments.

The bug only seems to happen if navigating by clicking on arrows.
Navigation by swiping the calendar works correctly and appointments are present on cellDetails

@Indumathi1195R I the video, you switch >2 pages forward and >2 pages backwards.
The bug doesn't reproduce if you switch >2 pages from the content.
Try switching one page forward and return back to the page with the content to see the bug.

Here is a video from my product. Notice that by default, green crosses are displayed, but if I use the button to switch pages, only red crosses are visible.
