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 #

Make sure to check out examples and API docs for more details.

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,
         ),
       );
     });
   }
   

3. Manage multiple calendars in the same view with multiple columns

   Set columnIndex in Event

   Event(
      columnIndex: 2,
      ...
    )
   

   Set columns number, labels, colors and ratio (optional)

   EventsPlanner(
      controller: controller,
      columnsParam: ColumnsParam(
        columns: 4,
        columnsLabels: ["Tennis", "Foot", "Bad"],
        columnsWidthRatio: [1 / 3, 1 / 3, 1 / 3],
        columnsColors: [
          Colors.yellow.pastel,
          Colors.green.pastel,
          Colors.blueAccent.pastel,
        ],
      ),
   );

Local #

The package does not support locales itself, so as not to import additional dependencies like intl which may cause dependency conflicts.

However, all texts are easily customizable. You can use intl to translate the texts into the desired language. Local example
