Overview

The Flutter Calendar, or scheduler library, was natively written in Dart and has eight built-in, configurable view modes that provide basic functionalities for scheduling, managing, and representing appointments efficiently. This Flutter Calendar widget exposes a clean and convenient user interface for custom working days and working hours, and basic calendar operations such as date navigation and selection.

Recurring events

Easily configure recurring events on a daily, weekly, monthly, or yearly basis. You can also skip or change an occurrence of a recurring appointment.

@override
Widget build(BuildContext context) {
 return Scaffold(

 appointmentDisplayMode: MonthAppointmentDisplayMode.appointment),
 ));
}

List<Meeting> _getDataSource() {
 final List<Meeting> meetings = <Meeting>[];
 final DateTime today = DateTime.now();
 final DateTime startTime =
 DateTime(today.year, today.month, today.day, 9, 0, 0);
 final DateTime endTime = startTime.add(const Duration(hours: 2));
 meetings.add(Meeting(
 'Conference', startTime, endTime, const Color(0xFF0F8644), false));
 return meetings;
}


class MeetingDataSource extends CalendarDataSource {
 MeetingDataSource(List<Meeting> source) {
 appointments = source;
 }

 @override
 DateTime getStartTime(int index) {
 return appointments![index].from;
 }
