Usage

2import Slider from "react-native-smooth-slider";
3import {AppRegistry, StyleSheet, Text} from "react-native";

5// if react-native-gesture-handler@1.x, no need <GestureHandlerRootView />
6// but just <View />, ref to
7// https://docs.swmansion.com/react-native-gesture-handler/docs/guides/migrating-off-rnghenabledroot/
8// You should put <GestureHandlerRootView /> in your root component,
9// example below is just playing the role of a root component
10import {GestureHandlerRootView} from 'react-native-gesture-handler';

12class SliderExample extends React.Component {
13  state = {
14    value: 0.2

24        />
25        <Text>
26          Value: {this.state.value}

Props

Prop	Type	Optional	Default	Description
value	number	Yes	0	Initial value of the slider
disabled	bool	Yes	false	If true the user won't be able to move the slider
minimumValue	number	Yes	0	Initial minimum value of the slider
maximumValue	number	Yes	1	Initial maximum value of the slider
step	number	Yes	0	Step value of the slider. The value should be between 0 and maximumValue - minimumValue)
minimumTrackTintColor	string	Yes	'#3f3f3f'	The color used for the track to the left of the button
maximumTrackTintColor	string	Yes	'#b3b3b3'	The color used for the track to the right of the button
thumbTintColor	string	Yes	'#343434'	The color used for the thumb
thumbTouchSize	object	Yes	{width: 40, height: 40}	The size of the touch area that allows moving the thumb. The touch area has the same center as the visible thumb. This allows to have a visually small thumb while still allowing the user to move it easily.
moveVelocityThreshold	number	Yes	2000	Prevent onValueChange if velocityX or velocityY (vertical is true) of nativeEvent is over the moveVelocityThreshold
onValueChange	function	Yes		Callback continuously called while the user is dragging the slider and the dragging movement speed is below the moveVelocityThreshold
onSlidingStart	function	Yes		Callback called when the user starts changing the value (e.g. when the slider is pressed)
onSlidingComplete	function	Yes		Callback called when the user finishes changing the value (e.g. when the slider is released)
style	style	Yes		The style applied to the slider container
trackStyle	style	Yes		The style applied to the track
trackImage	source	Yes		Sets an image for the track.
thumbStyle	style	Yes		The style applied to the thumb
thumbImage	source	Yes		Sets an image for the thumb.
vertical	bool	Yes	false	Set this to true to be a vertical slider.
useNativeDriver	bool	Yes	false	The useNativeDriver parameter in Animated used by react-native-gesture-handler when the user change the value. Default value is false, because some Android phone PanGestureHandler causes Animated Value to jump when using native driver
animateTransitions	bool	Yes	false	Set to true to animate values with default 'timing' animation type when value in next props is different.
animationType	string	Yes	'timing'	Custom Animation type when value in next props is different. 'spring' or 'timing'.
animationConfig	object	Yes	undefined	Used to configure the animation parameters when value in next props is different. These are the same parameters in the Animated library.

Methods

setValue(value)

In some use case e.g. "tension rod", it's more convenient to use method instead of prop to restore original positon of the tension rod. Below is a vertical tension rod example screenshot.
