throw PlatformException error when trying to use Google Authentication

Question

I am trying to use google authentication to log in to my app. Previously, I had this code running perfectly on my other laptop, but now that I have moved the same code and setup to another machine I am facing issues.

I have added SHA1 and SHA256 keys into my firebase, added the google-services.json file in my app folder. Currently, when I click my button to sign in with google, it shows me my account and let's me click it. However, upon clicking, it automatically redirects me to the messages_codecs.dart file and highlights this line throw PlatformException(code: errorCode, message: errorMessage as String?, details: errorDetails, stacktrace: errorStacktrace);

I was initially facing this identical error upon clicking on my sign in button, but then realized I was not using a AVM with google play store enabled. After changing that, it brings me through the sign in process, but after gives the same error.

You can find my whole file structure here. It is inside this question - StreamBuilder issue - snapshot.connectionState == ConnectionState.waiting when a TextFormField widget is clicked.,

I have searched and tried every solution online but nothing seems to work

Here is my flutter doctor -v
