This looks like an android configuration problem.

The solution is to add the dependencies to your android project.

The first step is to follow the instructions on Firebase Auth's pub.dev page

You can do this by adding the following lines to your android/build.gradle file:

dependencies {
    // Example existing classpath
    classpath 'com.android.tools.build:gradle:3.2.1'
   // Add the google services classpath
   classpath 'com.google.gms:google-services:4.3.0'
 }

and adding the following line to the bottom of your android/app/build.gradle file

  apply plugin: 'com.google.gms.google-services'

The next thing to do is add the Firebase Auth plugin to your android implementations

To do this you should follow the instructions => https://firebase.google.com/docs/android/setup#available-libraries
