Compile a Flutter project that uses Google Maps API

I have a flutter project which uses Google Maps services. I am unable to compile the project and getting the below error.FAILURE: Build failed with an exception.* What went wrong:Execution failed for task ':app:processDebugGoogleServices'.> No matching client found for package name 'com.xxx.xxxxx.driver.new'* 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.* Get more help at https://help.gradle.orgBUILD FAILED in 21sError: Gradle task assembleDebug failed with exit code 1The requirement of the project is to suggest the changes that needs to be made to get the app running

More details:

Is this project for business or personal use? For an existing business
What information should successful freelancers include in their application? Detailed project proposals
How soon do you need your project completed? ASAP

Access to the Google Cloud Console and associated APIs is available. Setting up the Google Services JSON file is already completed. Include detailed steps on setting up the package name correctly in the Flutter project. I need assistance with the full project setup.

I've already tried some solutions, but the issue persists. Focus on fixing the compile errors. Ongoing support will be needed after the initial setup. I have made recent changes to the project configuration. Use the recent versions of Flutter or Dart. I have confirmed the package name in the project configuration.
