Barcode scanning using react native
<p>I am using react-native-camera to build a barcode scanner for Android and iOS both.</p>

<p>I am able to scan the barcode in iOS but the issue is there is no visual for the scanning boundary. And I want the whole screen to be able to scan the bar code not just the middle of the screen.</p>

<p>Is there any way around it?
If there is some other library that would also work for me.</p>
