Simple and clean flutter calendar with ability to slide up/down to show weekly/monthly calendar.

flutter_clean_calendar #

Simple flutter calendar based on flutter_calendar package. Thanks to @AppleEducate for his contributions. You can pull up and down the calendar to show between weekly/monthly calendar. It shows the number of events for thats specific date. It shows the already Done events in other color

Breaking Changes #

  • Introduction of 'CleanCalendarEvent' class. This makes the former syntax of the 'Map' that stores the events incompatible.

Usage #

Embed the 'Calendar' widget in a column. Below the calendar (as the second widget in the Column) place a 'ListView.builder' widget for rendereing the list of events.

  mainAxisSize: MainAxisSize.max,
  children: <Widget>[
      child: Calendar(
        startOnMonday: true,
        weekDays: ['Mo', 'Di', 'Mi', 'Do', 'Fr', 'Sa', 'So'],
        events: _events,
        onRangeSelected: (range) =>
            print('Range is ${range.from}, ${range.to}'),
        onDateSelected: (date) => _handleNewDate(date),
        isExpandable: true,
        eventDoneColor: Colors.green,
        selectedColor: Colors.pink,
        todayColor: Colors.blue,
        eventColor: Colors.grey,
        locale: 'de_DE',
        todayButtonText: 'Heute',
        expandableDateFormat: 'EEEE, dd. MMMM yyyy',
        dayOfWeekStyle: TextStyle(
            color: Colors.black,
            fontWeight: FontWeight.w800,
            fontSize: 11),


/// This function [_buildEventList] constructs the list of events of a selected day. This
/// list is rendered below the week view or the month view.
Widget _buildEventList() {
  return Expanded(
    child: ListView.builder(
      padding: EdgeInsets.all(0.0),
      itemBuilder: (BuildContext context, int index) {
        final CleanCalendarEvent event = _selectedEvents[index];
        final String start =
        final String end =
        return ListTile(
              EdgeInsets.only(left: 2.0, right: 8.0, top: 2.0, bottom: 2.0),
          leading: Container(
            width: 10.0,
            color: event.color,
          title: Text(event.summary),
              event.description.isNotEmpty ? Text(event.description) : null,
          trailing: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [Text(start), Text(end)],
          onTap: () {},
      itemCount: _selectedEvents.length,

Sample event data #

The syntax of the event map changed due to the introduction of the 'CleanCalendarEvent' class.

final Map<DateTime, List<CleanCalendarEvent>> _events = {
    DateTime(DateTime.now().year, DateTime.now().month, DateTime.now().day): [
      CleanCalendarEvent('Event A',
          startTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day, 10, 0),
          endTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day, 12, 0),
          description: 'A special event',
          color: Colors.blue[700]),
    DateTime(DateTime.now().year, DateTime.now().month, DateTime.now().day + 2):
      CleanCalendarEvent('Event B',
          startTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day + 2, 10, 0),
          endTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day + 2, 12, 0),
          color: Colors.orange),
      CleanCalendarEvent('Event C',
          startTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day + 2, 14, 30),
          endTime: DateTime(DateTime.now().year, DateTime.now().month,
              DateTime.now().day + 2, 17, 0),
          color: Colors.pink),
