Installing #

  1. Add dependencies to pubspec.yaml

    Get the latest version in the 'Installing' tab on pub.dev

    dependencies:
        infinite_calendar_view: <latest-version>
    
  2. Run pub get.

    flutter pub get
    
  3. Import package.

    import 'package:infinite_calendar_view/infinite_calendar_view.dart';
    

Implementation #

  1. Init controller.

     EventsController controller = EventsController();
    
  2. Add calendar views.

    For 1 Day Planner View

    Scaffold(
        body: EventsPlanner(
          controller: controller,
          daysShowed : 1
        ),
    );
    

    For 3 Days Planner View

    Scaffold(
        body: EventsPlanner(
          controller: controller,
          daysShowed : 3
        ),
    );
    

    For List View

    Scaffold(
        body: EventsList(
          controller: controller,
        ),
    );
    
  3. Use controller to add or remove events when you want.

    To Add event:

    final event = Event(
       startTime: DateTime(2024, 8, 10, 8, 0),
       endTime: DateTime(2024, 8, 10, 9, 0),
       title: "Event1"
    );
    
    controller.updateCalendarData((calendarData) {
      calendarData.addEvents([event]);
    });
    

    To Add full day event:

    final fullDayEvent = FullDayEvent(
       title: "Full Day Event1"
    );
    
    controller.updateCalendarData((calendarData) {
      calendarData.addFullDayEvents(DateTime(2024, 8, 10), [event]);
    });
    

    As soon as you add or remove events from the controller, it will automatically update the calendar view assigned to that controller.

  4. Use GlobalKey to jump to a specific date.

     GlobalKey<InfiniteEventPlannerState> key = GlobalKey<InfiniteEventPlannerState>();
    

    Add key in EventsPlanner or EventsList

     EventsPlanner(
       key : key
       ...
     )
    

    Jump to date

     key.currentState?.jumpToDate(DateTime(2024, 8, 10))
    

More on the infinite calendar view #

  1. For Pinch To Zoom

    EventsPlanner(
       controller: controller,
       pinchToZoomParam: PinchToZoomParameters(
          pinchToZoom: true,
          onZoomChange: (heightPerMinute) {},
          pinchToZoomMinHeightPerMinute: 0.5,
          pinchToZoomMaxHeightPerMinute: 2.5,
          pinchToZoomSpeed: 1,
       ),
    );
    
  2. For Draggable Event

    EventsPlanner(
       controller: controller,
       dayParam: DayParam(
         dayEventBuilder: (event, height, width, heightPerMinute) {
           return DraggableEventWidget(
             event: event,
             height: height,
             width: width,
             heightPerMinute: heightPerMinute,
             onDragEnd: (exactStartDateTime, exactEndDateTime, roundStartDateTime, roundEndDateTime) {
               moveEvent(event, roundStartDateTime, roundEndDateTime);
             },
             child: DefaultDayEvent(
               height: height,
               width: width,
               title: event.title,
               description: event.description,
             ),
           );
         },
       ),
    );
    
    void moveEvent(Event oldEvent, DateTime roundStartDateTime, DateTime roundEndDateTime) {
      controller.updateCalendarData((calendarData) {
        calendarData.updateEvent(
          oldEvent: oldEvent,
          newEvent: oldEvent.copyWith(
            startTime: roundStartDateTime,
            endTime: roundEndDateTime,
          ),
        );
      });
    }
