Barcode scanner

Hey,
On a project I am working on I would like to try and get a barcode scanner working on mobile. There doesn’t seem to be any current plugins that are compatible with the engine right now and I am not sure how to go about setting one up. I did see an open-source project on GitHub that has various code for a barcode scanner. But I don’t know where to start to get it working… ( GitHub - zxing/zxing: ZXing ("Zebra Crossing") barcode scanning library for Java, Android ). I would imagine one would download this into the project but I am not sure where it would go and how to get it connected with the rest of the project. I am also thinking about would it would take to get permissions to work on Android and IOS but I don’t have much experience with using code to setting up Android and IOS specific tasks like this.

Any help would be appreciated.
