Please before mark it as duplicate read all the details. I get this error when working in firebase google sign in :
PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)
I add both SHA1 and SHA256 and support email and the internet connection permission and all what I found needed in docs, tutorials,Stacoverflow answer but still getting the above error.
also tried flutter clean
,invalidate cache/ restart
,deleting the app ..
The amazing thing is when I tried Firebase Email/password
Auth it worked fine but google auth isn't working !
