How to customize schedule view month header builder in Flutter Calendar?
In the Flutter Event Calendar, you can customize the schedule view month header using the scheduleViewMonthHeaderBuilder property of the calendar.
STEP 1: Create a folder for images and add the required images in the folder and specify the images folder under the assets of the Pubspec file.
flutter: # The following line ensures that the Material Icons font is # included with your application, so that you can use the icons in # the material Icons class. uses-material-design: true assets: - images/
STEP 2: Use the required widget for the schedule view month header for customization. In this sample we are using Image widget for schedule view month header customization.
Widget scheduleViewHeaderBuilder(
BuildContext buildContext, ScheduleViewMonthHeaderDetails details) {
final String monthName = _getMonthName(details.date.month);
return Stack(
children: [
Image(
image: ExactAssetImage('images/' + monthName + '.png'),
fit: BoxFit.cover,
width: details.bounds.width,
height: details.bounds.height),
Positioned(
left: 55,
right: 0,
top: 20,
bottom: 0,
child: Text(
monthName + ' ' + details.date.year.toString(),
style: TextStyle(fontSize: 18),
),
)
],
);
}
STEP 3: Based on the integer value updated the month string.
String _getMonthName(int month) {
if (month == 01) {
return 'January';
} else if (month == 02) {
return 'February';
} else if (month == 03) {
return 'March';
} else if (month == 04) {
return 'April';
} else if (month == 05) {
return 'May';
} else if (month == 06) {
return 'June';
} else if (month == 07) {
return 'July';
} else if (month == 08) {
return 'August';
} else if (month == 09) {
return 'September';
} else if (month == 10) {
return 'October';
} else if (month == 11) {
return 'November';
} else {
return 'December';
}
}
STEP 4: Assign that widget to the scheduleViewMonthHeaderBuilder property of the calendar.
child: SfCalendar( view: CalendarView.schedule, dataSource: _getDataSource(), scheduleViewMonthHeaderBuilder: scheduleViewHeaderBuilder, ),
