I am working on a React Native app that scans barcodes. I want to enable the user the toggle the light on and off with the press of a button. Right now the light stays on at all times. Would this be possible with the React Native camera component? Thank You!

class CameraScreen extends React.Component {

  state = {

    isCameraReady: false

  };



  constructor(props) {

    super(props);

    this.handleCameraReady = this.handleCameraReady.bind(this);

    this.state = {

      camera: {

        type: RNCamera.Constants.Type.back

      }

    };

  }

  handleCameraReady() {

    this.setState({

      isCameraReady: true

    });

  }



  onBarCodeRead = data => {

    this.setState({ scanned: true });

    const DATA_SKU = data.data.split(*);

    const SKU = DATA_SKU[0];

    const STK_ID = DATA_SKU[1] !== undefined ? DATA_SKU[1] : ;

    this.setState({ showCamera: false });

    this.props.navigation.navigate(Home, {

      scanDataSku: SKU,

      scanDataStkID: STK_ID

    });

  };



  render() {

    return (

      <SafeAreaView style={styles.container}>

        <RNCamera

          style={styles.container}

          onBarCodeRead={this.onBarCodeRead}

          ref={cam => (this.camera = cam)}

          cameraProps={{ captureAudio: false }}

          flashMode={

            this.state.isCameraReady

              ? RNCamera.Constants.FlashMode.torch

              : RNCamera.Constants.FlashMode.off

          }

          onCameraReady={this.handleCameraReady}

        ></RNCamera>

        <View style={styles.bottomNav}>

          <TouchableOpacity

            onPress={() => this.props.navigation.navigate(Home)}

            style={styles.bottomBtn}

          >

            <Text style={styles.bottomTxt}>Back</Text>

          </TouchableOpacity>

          <TouchableOpacity style={styles.bottomBtn}>

            <Text style={styles.bottomTxt}>Light</Text>

          </TouchableOpacity>

        </View>

      </SafeAreaView>

    );

  }

}
