I have also updated my flutter to the latest version I still get this error. What am I doing wrong?

It should be
apply plugin: 'com.google.gms.google-services'
Dot, not colon.

Firstly：
you need add classpath 'com.google.gms:google-services:4.3.3' in your project-level build.gradle
Then:
add "com.google.gms:google-services" in android/app/build.gradle file
I guess you missed firset step. Here is the doc https://firebase.google.com/docs/cloud-messaging/android/client

Followed procedures.
Flutter clean

It looks like you are working on an older flutter project, try a few things and see if these help.
1) Update your flutter SDK. You are currently using a pretty old version of flutter, and a beta build that was never a stable release. Even if this doesnt solve your problem it would be wise to upgrade. You can do so by running flutter upgrade in your terminal.
2) You may be trying to use an older version of certain firebase packages, including messaging. Try changing classpath 'com.google.gms:google-services:4.3.0'
in your project gradle.build to classpath 'com.google.gms:google-services:3.2.1'. Do this only if updating your flutter SDK doesnt fix the issue, and if this doesnt help change it back.
3) Try increasing your minSDKVersion for the project in the app-level/build.gradle, in the past when I have had similar issues this fixed my problems around sdk version 21.

The error you've provided is complete, but build errors are usually caused by the added package not being installed correctly. Running flutter clean then flutter pub get should do the job. Also, depending on the Firebase products that you're using, you only need to use Firebase CLI and flutterfire_cli to setup Firebase in your Flutter project.
