Turn flashlight on/off In QRcodeScanner React native

im using react-native-qrcode-scanner and what i want to do is : when user press on a flashlight icon flashLight go on i done this :

<QRCodeScanner
        showMarker
        onRead={this.onSuccess.bind(this)}
        cameraStyle={{ height: SCREEN_HEIGHT }}
        cameraProps={{ flashMode: this.state.flashLight ? RNCamera.Constants.FlashMode.on : RNCamera.Constants.FlashMode.off, captureAudio: false }}

camera prop works but when i change the state.flashLight (true or false) the flashLight not change

any Idea how change camera prop with state ??

Solution

  • Try to replace:

    RNCamera.Constants.FlashMode.on

    with: 

    RNCamera.Constants.FlashMode.torch

    Does the flashlight turn on now?
