@adrianso/react-native-device-brightness

npm version

This is a native module for React Native to control the screen brightness.

It is a fork of https://github.com/Calvin-Huang/react-native-device-brightness, and has added the following features:

  • React Native 0.60 compatibility
  • iOS 13 compatibility

Installation

yarn add @adrianso/react-native-device-brightness

Linking

This module supports auto-linking for React Native version 0.60 and above. No additional steps are required.

Usage

Important: Brightness Level only accept value 0 to 1.

  • Adjusting screen brightness will make iOS's Auto-Brightness function do nothing.
  • Adjusting screen brightness in Android only works in App and will reset to system setting exiting App.
import DeviceBrightness from 'react-native-device-brightness';

// Setting brightness
DeviceBrightness.setBrightnessLevel(brightness);

// Getting brightness
const brightness = await DeviceBrightness.getBrightnessLevel();
console.log(brightness);

// Getting system brightness (Android only)
const brightness = await DeviceBrightness.getSystemBrightnessLevel();
console.log(brightness);
