How to change the month header format in the Flutter Calendar
In the Flutter Event Calendar, you can customize the month header format using the headerDateFormat property.
Use the onViewChanged callback to dynamically change the header format based on different calendar views.
child: SfCalendar(
view: CalendarView.day,
controller: _controller,
allowedViews: [
CalendarView.day,
CalendarView.week,
CalendarView.workWeek,
CalendarView.month,
CalendarView.timelineDay,
CalendarView.timelineWeek,
CalendarView.timelineWorkWeek,
CalendarView.timelineMonth,
CalendarView.schedule
],
dataSource: _getCalendarDataSource(),
headerDateFormat: _headerFormat,
onViewChanged: viewChanged,
)
void viewChanged(ViewChangedDetails viewChangedDetails) {
if (_controller.view == CalendarView.day) {
_headerFormat = 'yyy MMM';
} else if (_controller.view == CalendarView.week ||
_controller.view == CalendarView.workWeek ||
_controller.view == CalendarView.timelineDay ||
_controller.view == CalendarView.timelineMonth) {
_headerFormat = 'MMM yyy';
} else if (_controller.view == CalendarView.month) {
_headerFormat = 'MMMM yy';
} else if (_controller.view == CalendarView.timelineWeek ||
_controller.view == CalendarView.timelineWorkWeek) {
_headerFormat = 'MMM yy';
} else {
_headerFormat = 'yyy';
}
SchedulerBinding.instance!.addPostFrameCallback((timeStamp) {
setState(() {
});
});
}
