Before mark it as duplicate please read the question.
I have set both SHA1 and SHA256 in my google console.
I have tried many way but still facing error.
Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
Also tried with Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null) and other so many.
Where I'm still missing ?
you can try to do a
flutter clean
to rebuild from 0 the project. It works for me.A lot can go wrong and I struggled for a very long time to fix this issue. My fix was that I needed to select the support email address in the settings of my firebase project.
Good luck
