How to customize appointments using custom builder in the Flutter Calendar?
In the Flutter Event Calendar, you can add the custom builder for appointments by using the appointmentBuilder property of the calendar.
STEP 1: You can use any widget for appointment builder. Here we are using Text and Icon widget for customization.
Widget appointmentBuilder(BuildContext context,
CalendarAppointmentDetails calendarAppointmentDetails) {
final Appointment appointment =
calendarAppointmentDetails.appointments.first;
return Column(
children: [
Container(
width: calendarAppointmentDetails.bounds.width,
height: calendarAppointmentDetails.bounds.height / 2,
color: appointment.color,
child: Center(
child: Icon(
Icons.group,
color: Colors.black,
),
)),
Container(
width: calendarAppointmentDetails.bounds.width,
height: calendarAppointmentDetails.bounds.height / 2,
color: appointment.color,
child: Text(
appointment.subject +
DateFormat(' (hh:mm a').format(appointment.startTime) +
'-' +
DateFormat('hh:mm a)').format(appointment.endTime),
textAlign: TextAlign.center,style: TextStyle(fontSize: 10),
),
)
],
);
}
STEP 2: Assign that widget to the appointmentBuilder property of the calendar.
child: SfCalendar( view: CalendarView.week, allowedViews: <CalendarView>[ CalendarView.day, CalendarView.workWeek, CalendarView.week, CalendarView.month, CalendarView.timelineDay, CalendarView.timelineWeek, CalendarView.timelineWorkWeek, CalendarView.timelineMonth, CalendarView.schedule ], dataSource: _getCalendarDataSource(), monthViewSettings: MonthViewSettings(showAgenda: true), timeSlotViewSettings: TimeSlotViewSettings(timelineAppointmentHeight: 100), appointmentBuilder: appointmentBuilder, )),
