dateFormat property Null safety

DateFormat? dateFormat
final

Formats the date labels. It is mandatory for date SfRangeSelector.

For date values, the range selector 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 format in SfRangeSelector.

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

SfRangeSelector(
  min: DateTime(2000, 01, 01, 00),
  max: DateTime(2005, 12, 31, 24),
  initialValues: _initialValues,
  interval: 1,
  showLabels: true,
  showTicks: true,
  dateFormat: DateFormat.y(),
  dateIntervalType: DateIntervalType.years,
  child: Container(
      height: 200,
      color: Colors.green[100],
   ),
)
