Simple flutter calendar based on flutter_clean_calendar package. This package offers some extra functionality. It introduced a new NeatCleanCalendarEvent object, that gets used as the data component transfered the calendar widget as a parameter. So it is possible now to color the dots in the Calendartiles with a color corresponding to the event.
The event list below the calendar view is generated bei the package. Here the extra data of the NetCleanCalendarEvent objects again come into play.
The package is highly customizable.
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.
