Flutter app fails to log in using google Sign In

Question

Edit :- Interestingly my practice app with exact same code shows same console logs but work absolutely fine but the main app (this app) doesnt work.

My app was working fine till a few hours ago but since morning login fails with this error

E/flutter (24958): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Stackoverflow says to change com.android.tools.build:gradle. How did this suddenly happen I dint even touch the code.

Console:

Did you recently add the facebook plugin? Please add your login code and pubspec.yaml — Siddharth Agrawal

@SiddharthAgrawal No I didnt. Login Code as in google sign in code? I dont think that would be a problem cuz same copy pasted code is working on a different practice app — Sid

@Sid and your pubspec? Maybe one of the modules there is causing the problem — Siddharth Agrawal

Indicate that there is an error with your SHA1 key. I think due to the new windows update the key got changed in your computer. Just generate a new one and replace it

The Platform Exception is because firebase is not being able to authenticate. Try catching the error and see the error code.

try {
[Firebase Login]
}
on PlatformException catch(error) {
print(error.code)
}
