EventController remove event don't work

#28

I have a CalendarControllerProvider with an EventController. When i try to do :
_eventController.remove(event);

I've got this error :

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Concurrent modification during iteration: Instance(length:1224) of '_GrowableList'.
E/flutter (19491): #0      ListIterator.moveNext (dart:_internal/iterable.dart:336:7)
E/flutter (19491): #1      _MonthEvent.removeEvent (package:calendar_view/src/event_controller.dart:204:21)
E/flutter (19491): #2      _YearEvent.removeEvent (package:calendar_view/src/event_controller.dart:174:11)

E/flutter (19491): #4      _CalendarPageState.showCreateEditEventDialog (package:myapp/page/calendar_page/calendar_page.dart:468:26)

I think it's because in MonthEvent, in removeEvent (line 203). We try to remove an event when we read the list.
