Update 5 April '18 :

react-native-firebase-phone-auth-corrected

This npm includes a correction over react-native-firebase-phone-auth npm from given link https://www.npmjs.com/package/react-native-firebase-phone-auth :-

Problem in Android : -
1. In “react-native-firebase-phone-auth” library firebase object has not created in “RNFirebasePhoneAuthModule.java”. They are already implemented the firebase object logic but code is commented out.
2. method does not override or implement a method from a supertype
@override.

Resolution for Android : -
1. Uncomment FirebaseOptions Builder object from “RNFirebasePhoneAuthModule.java” and Comment FirebaseApp.initializeApp() method without firebase object parameter.
2. Removed override method “createJSModules()” From "RNFirebasePhoneAuthPackage.java”. Resolution suggested by the owner of “react-native-firebase-phone-auth” library from given url https://github.com/ashinga48/React-Native-Firebase-Phone-Authentication/issues/3 .
