i following firebase implementation documentation but application at tun time show this issue. let me know how to fix it . this is my work. https://github.com/ArunaMahaGamage/React_Native_Firebase_Authentication

Encountering same issue here after upgrading to 0.59
I encountered this same issue and it was because I glazed over a few steps in the setup process. In particular:
In MainApplication.java:
import io.invertase.firebase.notifications.RNFirebaseNotificationsPackage;
import io.invertase.firebase.messaging.RNFirebaseMessagingPackage;
and then add the following to the getPackages() list:
new RNFirebaseMessagingPackage(),
new RNFirebaseNotificationsPackage()
Finally, in your app build.gradle, add the following to your dependencies:
implementation "com.google.firebase:firebase-messaging:17.3.4"
implementation 'me.leolin:ShortcutBadger:1.1.21@aar'
That fixed it for me.
@ArunaMahaGamage looks like you're using an old version of the Firebase Auth Android SDK here (11.8.0)
This should be 16.1.0 as the docs indicate.
