Installing

Add dependencies to pubspec.yaml

Get the latest version in the 'Installing' tab on pub.dev
```
dependencies:
    infinite_calendar_view: <latest-version>
```
Run pub get.
```
flutter pub get
```

Import package.

import 'package:infinite_calendar_view/infinite_calendar_view.dart';

Implementation

Init controller.

 EventsController controller = EventsController();

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,
    ),
);

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.

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))

For Pinch To Zoom

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

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,
      ),
    );
  });
}

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,
     ],
   ),
);
