Flutter Build Failed: Execution failed for task ':app:mapDebugSourceSetPaths'

I recently upgrade my Flutter app from compileSdkVersion & targetSdkVersion 32 to 33 then to 34, along with upgrading AGP to 7.4, migrating the Flutter’s Gradle plugins and updating all other dependencies in androidappbuild.gradle to latest version. I tried to run the app but getting the following errors:

Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mapDebugSourceSetPaths'.
> Querying the mapped value of map(flatmap(provider(task 'processDebugGoogleServices', class com.google.gms.googleservices.GoogleServicesTask))) before task ':app:processDebugGoogleServices' has completed is not supported

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

I have tried to downgrade com.google.gms.google-services to lower version such as 4.3.15 but it doesn’t work. Please advise.
