npm version
A simple React Native plugin to switch a flashlight on/off.
Currently supports both iOS (>= 8.0) and Android (all versions).
Applies the permission checks on Android API >=25 devices. Below API 25, Android will automatically require the user to accept permissions on install / update.


npm install --save react-native-torch
react-native link react-native-torch

Manual install


  1. npm install react-native-torch --save
  2. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
  3. Go to node_modulesreact-native-torch and add RCTTorch.xcodeproj
  4. Expand the RCTTorch.xcodeprojProducts folder
  5. In XCode, in the project navigator, select your project. Add libRCTTorch.a to your project's Build PhasesLink Binary With Libraries
  6. Click RCTTorch.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). In the Search Paths section, look for Header Search Paths and make sure it contains both $(SRCROOT)/../../react-native/React and $(SRCROOT)/../../../React - mark both as recursive.


Without permissions check

import Torch from 'react-native-torch';

Torch.switchState(true); // Turn ON
Torch.switchState(false); // Turn OFF

With extra permission check and dialog (Android only)

import Torch from 'react-native-torch';
import { Platform } from 'react-native';

if (Platform.OS === 'ios') {
} else {
	const cameraAllowed = await Torch.requestCameraPermission(
		'Camera Permissions', // dialog title
		'We require camera permissions to use the torch on the back of your phone.' // dialog body

	if (cameraAllowed) {

Android catch exception accessing Torch e.g. in emulator or if device doesn't have a torch

try {
	await Torch.switchState(newTorchState);
	this.setState({ isTorchOn: newTorchState });
} catch (e) {
		'We seem to have an issue accessing your torch',

NOTE: iOS fails silently, on Android, you can still call without the try/catch block and it won't cause a crash
A demo application TorchDemo is also available.
Android version has flow support.
