Ticks in Flutter Range Slider (SfRangeSlider)

4 May 202124 minutes to read

This section helps to learn about how to add major and minor ticks in the range slider.

Show major ticks

You can enable the major ticks on the track. It is a shape which is used to represent the major interval points of the track. The default value of showTicks property is false.

For example, if min is 0.0 and max is 10.0 and interval is 2.0, the range slider will render the major ticks at 0.0, 2.0, 4.0 and so on.

NOTE

Refer the tickShape and SfRangeSliderThemeData for customizing the major tick’s visual appearance.

Show minor ticks

It is used to represent the number of smaller ticks between two major ticks. For example, if min is 0.0 and max is 10.0 and interval is 2.0, the range slider will render the major ticks at 0.0, 2.0, 4.0 and so on. If minorTicksPerInterval is 1, then smaller ticks will be rendered on 1.0 and 3.0 and so on.

IMPORTANT

The default value of minorTicksPerInterval property is null and it must be greater than 0.

Range slider minor tick support

NOTE

Refer the showTicks to know about the rendering major ticks at given interval.

Refer the minorTickShape and SfRangeSliderThemeData for customizing the minor tick’s visual appearance.

Major ticks color

You can change the active and inactive major ticks color of the range slider using the activeTickColor and inactiveTickColor properties respectively.

The active side of the range slider is between start and end thumbs.

The inactive side of the range slider is between the min value and the left thumb, and the right thumb and the max value.

For RTL, the inactive side is between the max value and the left thumb, and the right thumb and the min value.

NOTE

You must import the theme.dart library from the Core package to use SfRangeSliderTheme.
