REMOVE THIS

rootProject.ext {
  set('FlutterFire', [
    FirebaseSDKVersion: '21.1.0'
  ])
}

in case you added it. works for me.

Make sure you have added google maven repo at the project level - 

allprojects {
    // ...
    repositories {
        google() // Google's Maven repository
        // ...
    }
}

And, add this line at the bottom of app level gradle file - 

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

If you're still getting error then change the google service version to 

classpath 'com.google.gms:google-services:4.2.0'

For more info, visit Firebase documentation.
