Calendar features

• Multiple calendar views - A wide range of built-in view modes are available: day, week, workweek, month, timeline day, timeline week, timeline workweek. The control allows you to conveniently customize every view with unique, view-specific options.

• Appointments - Appointments contain information on events scheduled at specific times. In addition to default appointments, users can use their own collections to connect a business entity to an appointment by mapping their fields, such as start time, end time, subject, notes, and recurrence.

• Recurring appointments - Easily configure recurring events to be repeated on a daily, weekly, monthly, or yearly basis with optimized recurrence options. You can also skip or change the occurrence of a recurring appointment.

• Time zone - Regardless of the time zone in your device, Calendar supports setting any required time zone for the control itself, as well as individual events.

• Flexible working days - Customize the work days in a workweek so that the remaining days will be hidden from view.

• First day of the week - Customize the first day of the week as needed. The default is Sunday.

• Custom start and end hours - Display the event calendar timeslot views with specific time durations by hiding the unwanted hours.

• Month agenda view - Display appointments in a list as shown in the following month view by clicking on a day.

• Appearance customization - Provide a uniform and consistent look with Calendar’s flexible appearance and format.

Installation

Getting started

Import the following package.

import 'package:syncfusion_flutter_calendar/calendar.dart';

Add Calendar to the widget tree

Add the Calendar widget as a child of any widget. Here, the calendar widget is added as a child of the scaffold widget.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: Container(
    child: SfCalendar(),
  ));
}

Change different calendar views

The SfCalendar widget provides seven different types of views to display dates. It can be assigned to the widget constructor by using view property. By default, the widget is assigned day View. The current date will be displayed initially for all the Calendar views.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfCalendar(
    view: CalendarView.month,
  ));
}

Add flexible working days and working hours

The default values for startHour and endHour are 0 and 24 to show all the time slots in time slot views. You can to set the startHour and endHour properties of timeSlotViewSettings to show only the required time duration for end users. You can set startHour and endHour in time duration to show the required time duration in minutes. You can also customize the nonworking days of a week by using the nonWorkingDays property of timeSlotViewSettings to show only the required days for the end users.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfCalendar(
    view: CalendarView.workWeek,
    timeSlotViewSettings: TimeSlotViewSettings(
        startHour: 9,
        endHour: 16,
        nonWorkingDays: <int>[DateTime.friday, DateTime.saturday]),
  ));
}

Change first day of week

The Calendar widget will be rendered with Sunday as the first day of the week, but you can customize it to any day by using the firstDayOfWeek property.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfCalendar(
    view: CalendarView.week,
    firstDayOfWeek: 1,
  ));
}

Add month agenda view

The Calendar month view displays a divided agenda view that is used to show the selected date’s appointments below the month. You can show the agenda view by setting showAgenda property to true in monthViewSettings.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfCalendar(
    view: CalendarView.month,
    monthViewSettings: MonthViewSettings(showAgenda: true),
  ));
}

Add data source

The Calendar widget has a built-in capability to handle appointment arrangement internally based on the appointment collections. You need to assign the created collection to the dataSource property. You can also map custom appointment data to our calendar.

@override
  Widget build(BuildContext context) {
    return Scaffold(
        body: SfCalendar(
      view: CalendarView.month,
      dataSource: MeetingDataSource(_getDataSource()),
      monthViewSettings: MonthViewSettings(
          appointmentDisplayMode: MonthAppointmentDisplayMode.appointment),
    ));
  }

  List<Meeting> _getDataSource() {
    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;
  }

  @override
  DateTime getEndTime(int index) {
    return appointments[index].to;
  }

  @override
  String getSubject(int index) {
    return appointments[index].eventName;
  }

  @override
  Color getColor(int index) {
    return appointments[index].background;
  }

  @override
  bool isAllDay(int index) {
    return appointments[index].isAllDay;
  }
}

class Meeting {
  Meeting(this.eventName, this.from, this.to, this.background, this.isAllDay);

  String eventName;
  DateTime from;
  DateTime to;
  Color background;
  bool isAllDay;
}
