Use controller to add or remove events.
To Add event:
final event = CalendarEventData(
date: DateTime(2021, 8, 10),
event: "Event 1",
);

CalendarControllerProvider.of(context).controller.add(event);
copied to clipboard
To Add events in range of dates:
final event = CalendarEventData(
date: DateTime(2021, 8, 10),
endDate: DateTime(2021,8,15),
event: "Event 1",
);

CalendarControllerProvider.of(context).controller.add(event);
copied to clipboard
To Remove event:
CalendarControllerProvider.of(context).controller.remove(event);
copied to clipboard
As soon as you add or remove events from the controller, it will
automatically update the
calendar view assigned to that controller.

for more info

Use GlobalKey to change the page or jump to a specific page or date.

Use of GlobalKey #
User needs to define global keys to access functionalities like changing a page

global key.
By assigning global keys to calendar views you can access methods and fields
defined by state class
of respected views.

Provide the same controller object to all calendar views used in the
project.
Wrap MaterialApp with CalendarControllerProvider and provide controller as
argument as defined
in Implementation.
