To solve this, please change this line of code:

classpath 'com.google.gms:google-services:3.2.1'

to

classpath 'com.google.gms:google-services:4.0.1'

and

implementation 'com.google.firebase:firebase-firestore:16.0.0'

to

implementation 'com.google.firebase:firebase-firestore:17.0.2'

And also don't forget to add the following dependecy which is now mandatory:

implementation 'com.google.firebase:firebase-core:16.0.1'

Also if you need to use Firebase Messaging then you should also add the following dependency:

implementation 'com.google.firebase:firebase-messaging:17.0.0'
