2. Add calendar views.

   For 1 Day Planner View

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

   copied to clipboard

   For 3 Days Planner View

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

   copied to clipboard

   For List View

   Scaffold(
       body: EventsList(
         controller: controller,
       ),
   );
   

   copied to clipboard

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]);
   });
   

   copied to clipboard

   To Add full day event:

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

   copied to clipboard

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

   copied to clipboard

   Add key in EventsPlanner or EventsList

    EventsPlanner(
      key : key
      ...
    )
   

   copied to clipboard

   Jump to date

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

         pinchToZoomMinHeightPerMinute: 0.5,
         pinchToZoomMaxHeightPerMinute: 2.5,

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,
            ),
          );
        },
      ),
   );
   

   copied to clipboard

   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,
      ...
    )
   

   copied to clipboard

   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
