Props below may have different types depending on valueType prop.

Methods

To call methods of RangeSlider you need to have a reference to it's instance.
React native provides 2 ways to do it:

...
<RangeSlider ref="_rangeSlider" />
...
this.refs._rangeSlider.setLowValue(42);
...

or

...
<RangeSlider ref={ component => this._rangeSlider = component } />
...
this._rangeSlider.setLowValue(42);
...

Available methods

Name	Description	Params
setLowValue	Set low value of slider	value: Number (or Date, if valueType is set to time)
setHighValue	Set high value of slider	value: Number (or Date, if valueType is set to time)

Callbacks

Name	Description	Params
onValueChanged	A callback to be called when value was changed. Type of lowValue and highValue will be Number if valueType is number and Date if valueType is time fromUser parameter is true if the value was changed because of user's interaction (not by calling setLowValue or setHighValue methods). Just like android's OnSeekbarChangeListener.	lowValue: number highValue: number fromUser: boolean
onTouchStart	Nothing to explain I think :)	-
onTouchEnd	Nothing to explain here too	-

Known issues

• Label's corner radius is not working on iOS
• Problems with expo (won't fix as I don't take Expo seriously)
