@react-native-community/slider

What is @react-native-community/slider?

@react-native-community/slider is a React Native component for creating sliders, which are UI elements that allow users to select a value from a range by moving a thumb along a track. This package is useful for scenarios where you need to capture a range of values, such as volume control, brightness adjustment, or any other numeric input.

What are @react-native-community/slider's main functionalities?

Basic Slider

This code demonstrates a basic slider with a minimum value of 0 and a maximum value of 1. The slider has custom colors for the minimum and maximum track.

import Slider from '@react-native-community/slider';
import React from 'react';
import { View } from 'react-native';

const BasicSlider = () => {
  return (
    <View>
      <Slider
        style={{width: 200, height: 40}}
        minimumValue={0}
        maximumValue={1}
        minimumTrackTintColor="#FFFFFF"
        maximumTrackTintColor="#000000"
      />
    </View>
  );
};

export default BasicSlider;

Slider with Custom Thumb

This code demonstrates a slider with a custom thumb image. The thumbImage prop is used to set a custom image for the slider's thumb.

import Slider from '@react-native-community/slider';
import React from 'react';
import { View, Image } from 'react-native';

const CustomThumbSlider = () => {
  return (
    <View>
      <Slider
        style={{width: 200, height: 40}}
        minimumValue={0}
        maximumValue={100}
        thumbImage={require('./path/to/thumbImage.png')}
      />
    </View>
  );
};

export default CustomThumbSlider;

Slider with Step Value

This code demonstrates a slider with a step value of 1. The step prop ensures that the slider's thumb moves in increments of 1.

import Slider from '@react-native-community/slider';
import React from 'react';
import { View } from 'react-native';

const StepSlider = () => {
  return (
    <View>
      <Slider
        style={{width: 200, height: 40}}
        minimumValue={0}
        maximumValue={10}
        step={1}
      />
    </View>
  );
};

export default StepSlider;

Other packages similar to @react-native-community/slider

react-native-slider

react-native-slider is another popular package for creating sliders in React Native. It offers similar functionality to @react-native-community/slider, including support for custom thumb images, track colors, and step values. However, @react-native-community/slider is more actively maintained and is part of the React Native Community, which may offer better support and integration with other community packages.

react-native-multi-slider

react-native-multi-slider is a package that allows for the creation of multi-point sliders, where users can select multiple values along a range. This package is useful for more complex scenarios where a single slider is not sufficient. It offers more advanced features compared to @react-native-community/slider, but may be overkill for simpler use cases.

Properties

Property	Description	Type	Platform
style	Used to style and layout the Slider. See StyleSheet.js and ViewStylePropTypes.js for more info.	View.style
disabled	If true the user won't be able to move the slider. Default value is false.	bool
maximumValue	Initial maximum value of the slider. Default value is 1.	number
minimumTrackTintColor	The color used for the track to the left of the button. Overrides the default blue gradient image on iOS.	color
minimumValue	Initial minimum value of the slider. Default value is 0.	number
lowerLimit	Slide lower limit. The user won't be able to slide below this limit.	number	Android, iOS, Web
upperLimit	Slide upper limit. The user won't be able to slide above this limit.	number	Android, iOS, Web
onSlidingStart	Callback that is called when the user picks up the slider. The initial value is passed as an argument to the callback handler.	function
onSlidingComplete	Callback that is called when the user releases the slider, regardless if the value has changed. The current value is passed as an argument to the callback handler.	function
onValueChange	Callback continuously called while the user is dragging the slider.	function
step	Step value of the slider. The value should be between 0 and (maximumValue - minimumValue). Default value is 0. On Windows OS the default value is 1% of slider's range (from minimumValue to maximumValue).	number
maximumTrackTintColor	The color used for the track to the right of the button. Overrides the default gray gradient image on iOS.	color
testID	Used to locate this view in UI automation tests.	string
value	Write-only property representing the value of the slider. Can be used to programmatically control the position of the thumb. Entered once at the beginning still acts as an initial value. Changing the value programmatically does not trigger any event. The value should be between minimumValue and maximumValue, which default to 0 and 1 respectively. Default value is 0. This is not a controlled component, you don't need to update the value during dragging.	number

Custom step marker and step numbers

It is possible to render default step numbers under your slider and to render custom step component and step marker.
This can be achieved by using:

renderStepNumber

Turns on the displaying of numbers of steps.
Numbers of steps are displayed under the track.
Two font sizes are available and they will be selected automatically depending on the overall number of steps.

StepMarker

Your custom component rendered for every step on the Slider, both the thumb and the rest of steps along the Slider's whole length.
This StepMarker prop accepts your custom component and provides it with the following parameters:

stepMarked: boolean;	Indicates whether that custom step is the one that the thum is currently on. If user drags or clicks on that step, thumb will be moved there and the stepMarked parameter will be set to true. Use it, to differentiate between rendering your custom thumb component, or your custom step marker.
currentValue: number;	Contains the `number` type saying at which value of the Slider the thumb currently is. Use it, for example, to render the Slider value on every step marker, or to render different step marker's variant depending on the Thumb position.
index: number;	Contains the index at which this exact instantiation of your custom step marker was rendered at. Use it if you would like to render step number within the step marker, or, for example, if you want to render many variants of step marker depending on their positions along the Slider's width.
min: number;	Minimum value of the Slider. It is equal to minimumValue and has the same default if not set.
max: number;	Maximum value of the Slider. It is equal to maximumValue and has the same default if not set.

Contributing

The main package implementation is done in the package/ directory. So when implementing changes there, make sure your code passes ESLint and the tests. Run the following to verify:

cd package/
npm run lint
npm run test

• Remember to cover your changes with tests if possible.

When creating an issue please remember to specify the platform which the issue occurs on.

Running the example app

While developing, you can run the example app to test your changes.

Setup

• Clone the repository
• Run npm install in the root directory to install dependencies.
• Run npm run example-<platform>, where platform can be: ios, android, windows

You can also do this manually by:

• Installing node modules for example app
• Installing pods for iOS app
• Running example app like always: npx react-native run-<platform>

New architecture setup (Fabric)

In order to use the new architecture some extra steps are needed.

iOS

• Install pods with new arch flag inside example/ios folder: RCT_NEW_ARCH_ENABLED=1 pod install
• Run npm run example-ios

Android

• Set newArchEnabled to true inside example/android/gradle.properties
• Run npm run example-android

If you are using React Native version lower than 0.70, you need to setup manual linking for Android to work.

Inside example/android/app/src/main/jni/Android.mk add these lines:

+ include $(NODE_MODULES_DIR)/@react-native-community/slider/android/build/generated/source/codegen/jni/Android.mk
include $(CLEAR_VARS)

    libreact_codegen_rncore \
+   libreact_codegen_ReactSlider \
    libreact_debug \

Inside example/android/app/src/main/jni/MainComponentsRegistry.cpp update these lines:

#include <react/renderer/components/rncore/ComponentDescriptors.h>
+ #include <react/renderer/components/ReactSlider/ComponentDescriptors.h>

...

MainComponentsRegistry::sharedProviderRegistry() {
  auto providerRegistry = CoreComponentsRegistry::sharedProviderRegistry();

  // Custom Fabric Components go here. You can register custom
  // components coming from your App or from 3rd party libraries here.
  //
  // providerRegistry->add(concreteComponentDescriptorProvider<
  //        AocViewerComponentDescriptor>());
+ providerRegistry->add(concreteComponentDescriptorProvider<RNCSliderComponentDescriptor>());

  return providerRegistry;
}
