How to show the appointment in agenda view using the programmatic date selection in the Flutter Calendar

In Flutter Date Range Picker, you can programmatically select the date and display the appointments in the agenda view using the `selectedDate` property of `CalendarController`.

STEP 1: In the `onViewChanged` callback, use the `selectedDate` property of the `CalendarController`,   to show appointments of the selected date in the agenda view. you can programmatically set the `selectedDate` for all months.

void viewChanged(ViewChangedDetails viewChangedDetails) {
  SchedulerBinding.instance!.addPostFrameCallback((duration) {
    var midDate = (viewChangedDetails
        .visibleDates[viewChangedDetails.visibleDates.length ~/ 2]);
    if (midDate.month == DateTime
        .now()
        .month)
      _calendarController.selectedDate = DateTime.now();
    else {
      _calendarController.selectedDate = DateTime(
        midDate.year,
        midDate.month,
        01,
        9,
        0,
        0,
      );
    }
  });
}

STEP 2: Place the calendar inside the body of the Scaffold widget.

home: Scaffold(
  body: SafeArea(
    child: SfCalendar(
      view: CalendarView.month,
      controller: _calendarController,
      monthViewSettings: MonthViewSettings(showAgenda: true),
      dataSource: getCalendarDataSource(),
      onViewChanged: viewChanged,
    ),
  ),
),
