I get a similar error.

PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null)

Have been trying several things mentioned on stackoverflow for the same. But still no luck. Any help is appreciated.

Did you set the SHA-1 for your app? See more here: https://github.com/flutter/flutter/issues/25640#issuecomment-449589417

Yes I tried that and ensured SHA-1 is added to the firebase console. Still it doesn't work. Anyone has this working?

i have setted own package name, generate new SHA-1, but no luck

@viju85 @namdroid Make sure you create a new app on Firebase with the new package name you've decided to keep. While creating the app, add the SHA1 by running the following (more docs)

 keytool -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore

The password is android. Then copy/paste the SHA1 into the settings page in Firebase for your app. Lastly, remember to rebuild and reinstall the app.

@VickySalunkhe @namdroid I finally got it working by following this solution.

"You need to add support gmail in settings of firebase" https://stackoverflow.com/a/56286513/341617.

Hope this helps.

Thanks @viju85 for pointing it out! I'll add that part to the getting started steps.
