Googleservices.json says not present when it is - firebase

Question

Im learning flutter and trying to install firebase and it keeps saying that "google-services.json" can not be found, even though I have it in the right place, also tried many other places what it actuall says is "Exit code 1 from: C:\Users\Samwise\Desktop\chatapp3\android\gradlew.bat app:properties:
Could not find google-services.json while looking in [src/nullnull/debug, src/debug/nullnull, src/nullnull, src/debug, src/nullnullDebug]
registerResGeneratingTask is deprecated, use registerGeneratedFolders(FileCollection)"
Thank you so much.

It is possible that Firebase version that uses google service 3.2.0 is not yet supported based on the comment in the repo issue:
Firebase has moved on to version 12+ and uses version 3.2.0 of the
google-services Gradle plugin. The flutter/plugins repo should follow
suit.
I have 3.1.2 happily working, so you could try that.
classpath 'com.google.gms:google-services:3.1.2'
