        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }

Usage:

import RFIDScanner, { RFIDScannerEvent } from 'react-native-zebra-rfid';

// Init and connect
RFIDScanner.init();

// Register callback
RFIDScanner.on(RFIDScannerEvent.TAGS, onRfidResult);

// Remove callback
RFIDScanner.removeon(RFIDScannerEvent.TAGS, onRfidResult);

// Shutdown
RFIDScanner.shutdown();

// Callback, tags is an array of strings
// Read triggered by hardware trigger, or 
// programmatically by calling
// RFIDScanner.read() or RFIDScanner.cancel()

const onRfidResult = (tags) => {
    console.info(' TAGS: ' + JSON.stringify(tags));
}
