A simple way to customize the screen of the BarcodeScanner

I need a simple way to customize the screen of the BarcodeScanner. How do I do this?

I assume you are referring to: https://github.com/phonegap/phonegap-plugin-barcodescanner

If so you just need to fork the project and customise the scanner overlays.

For example (iOS): https://github.com/phonegap/phonegap-plugin-barcodescanner/blob/master/src/ios/scannerOverlay.xib

Do you have any tutorials that teach you how to do this?
