import { DeviceEventEmitter } from "react-native";

//Add it in componentWillMount or somewhere where it will get executed at the start of app 
DeviceEventEmitter.addListener('GReferrerBroadcastReceiver', function (map) {
    console.log('Google Broadcast referrer data is: ' + map.referrer);
});

//Do not forget to remove the listener at componentWillUnmount 
componentWillUnmount() {
    DeviceEventEmitter.removeListener('GReferrerBroadcastReceiver');

import RNAndroidBroadcastReceiverForReferrer from 'react-native-android-broadcast-receiver-for-referrer'; 

//This will return the referrer value if we have got it other will return "NOT AVAILABLE"
let referrerValue = await RNAndroidBroadcastReceiverForReferrer.getReferrerData();
