Unable to detect constants from QRCodeScanner

What's happening?

when i add flashMode prop to the QRCodeScanner getting the above error

How can it be reproduced?

<QRCodeScanner onRead={this.onSuccess} flashMode={QRCodeScanner.Constants.FlashMode.torch} topContent={ <Text style={styles.centerText}> Go to <Text style={styles.textBold}>wikipedia.org/wiki/QR_code</Text> on your computer and scan the QR code. </Text> } bottomContent={ <TouchableOpacity style={styles.buttonTouchable}> <Text style={styles.buttonText}>OK. Got it!</Text> </TouchableOpacity> } />

Build details?

I have the same problem, try this `import { RNCamera as Camera } from 'react-native-camera';

Camera.Constants.FlashMode.torch `

@yaibait thanks it works

import { RNCamera as Camera } from 'react-native-camera';

Camera.Constants.FlashMode.torch

I don't think the above is correct for the latest. flashMode no longer exists on QRCodeScanner by the looks instead it takes cameraProps.

This is the solution for me using latest

  import QRCodeScanner from "react-native-qrcode-scanner";
  import { RNCamera as Camera } from "react-native-camera";

   <QRCodeScanner
      onRead={onSuccess}
      cameraProps={{ flashMode: Camera.Constants.FlashMode.auto }}
      topContent={<Text style={styles.centerText}>Test</Text>}
      bottomContent={
        <TouchableOpacity style={styles.buttonTouchable}>
          <Text style={styles.buttonText}>OK. Got it!</Text>
        </TouchableOpacity>
      }
    />

@moaazsidat why the constants it's no more available in QRCodeScanner? 🤔
