dateIntervalType property

DateIntervalType? dateIntervalType

The type of date interval. It is mandatory for date SfRangeSlider.

It can be years to seconds.

For date values, the range slider doesn’t have auto interval support. So, you may need to set interval, dateIntervalType, and dateFormat for date values, if labels, ticks, and dividers are needed.

Defaults to null.

This snippet shows how to set date interval type in SfRangeSlider.

SfRangeValues _values = SfRangeValues(
        DateTime(2002, 01, 01), DateTime(2003, 01, 01));

  min: DateTime(2000, 01, 01, 00),
  max: DateTime(2005, 12, 31, 24),
  values: _values,
  interval: 1,
  dateFormat: DateFormat.y(),
  dateIntervalType: DateIntervalType.years,
  onChanged: (SfRangeValues newValues) {
    setState(() {
      _values = newValues;


final DateIntervalType? dateIntervalType;
