Answer 1

Use this command to get your real SHA-1

cd android && keytool -list -v -keystore app/debug.keystore

And the password is: android

Put it on your android key on google

Answer 2

Your SHA1 and SHA256 are not correctly added to the Firebase.

1. Find the .keystore file. If you are having this error on a real device, you must be using other keystore file for that. List SHA keys using that exact file running: keytool -keystore path-to-keystore-file -list -v

2. Download google-services.json.

3. Configure GoogleSignin using client_id from where client_type is 3.

GoogleSignin.configure({
 offlineAccess: true,
 webClientId: 'your_client_id.apps.googleusercontent.com',
});
