RangeSlider In Flutter

Updated 31 May 2022


The RangeSlider In Flutter is a customizable widget for selecting a range of values.

In this blog, we are going to learn about the RangeSlider widget in flutter.

The RangeSlider component can offer us a single selection or multiple selections on track.

However,the values are updated by calling set state() within the RangeSlider onChange() callback.

Moreover, in order to have an interactive range slider, the RangeSlider widget must be created within a Stateful widget.

The RangeSlider consists of:

  1. A track on which we can move across to select the values.
  2. 2 Knobs indicating the minimum and maximum value of the range.
  3. and, value indicators that show the labels for the knob values when knobs are defined and showValueIndicator matches the type of slider.

Properties of RangeSlider:

Importantly, we will use SliderTheme and then add SliderThemeData. As a result, we will be able to see values displayed above the track.

In these theme data, we will add showValueIndicator, valueIndicatorColor, etc.
