Basic set up

Make sure to check out the example for more details.

Dynamic timeline requires you to provide firstDateTime, lastDateTime, labelBuilder and a list of items.

  • labelBuilder: Used to build the label of each mark, normally a dateFormat will be used.
  • items: The events of the timeline, who are positioned according to its start and end date times.

Another important property is intervalDuration, that is the lenght of time between each mark.

Example of a daily timeline.

    firstDateTime: DateTime(1970, 1, 1, 7),
    lastDateTime: DateTime(1970, 1, 1, 22),
    labelBuilder: DateFormat('HH:mm').format,
    intervalDuration: const Duration(hours: 1),
    children: [
        startDateTime: DateTime(1970, 1, 1, 7),
        endDateTime: DateTime(1970, 1, 1, 8),
        child: const Event(title: 'Event 1'),
        startDateTime: DateTime(1970, 1, 1, 10),
        endDateTime: DateTime(1970, 1, 1, 12),
        child: const Event(title: 'Event 2'),
        startDateTime: DateTime(1970, 1, 1, 15),
        endDateTime: DateTime(1970, 1, 1, 17),
        child: const Event(title: 'Event 3'),
