How To Solve PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null) Error ?

Solution 1: Generate SHA1 and SHA256 keys

1. Generate SHA1 and SHA256 keys.
2. Add both the SHA1 and SHA256 to firebase. (in you app settings)
3. Download google-services.json to android/app in your project folder.
4. In your terminal run the command flutter clean .
5. Run your flutter app.
6. Now your error must be solved.

Solution 2 : Generating a debug.keystore and registering it inside the app on Firebase

This Error Must be Because of you did not register a SHA fingerprint in firebase. Without  register a SHA fingerprint in firebase you cant use Google’s API.

I solved it by generating a debug.keystore and registering it inside the app on Firebase. Don’t forget to download the new google-services.json after that.

To Generate certificate fingerprint Follow below command in your windows terminal.

keytool -exportcert -list -v \ -alias <your-key-name> -keystore <path-to-production-keystore>

Output will be like below

The signing report will include the signing information for each of your app’s variants:

> Task :app:signingReport
Variant: debug
Config: debug
Store: ~/.android/debug.keystore
Alias: AndroidDebugKey
MD5: A5:88:41:04:8D:06:71:6D:FE:33:76:87:AC:AD:19:23
SHA1: A7:89:E5:05:C8:17:A1:22:EA:90:6E:A6:EA:A3:D4:8B:3A:30:AB:18
SHA-256: 05:A2:2C:35:EE:F2:51:23:72:4D:72:67:A5:6C:8C:58:22:2A:00:D6:DB:F6:45:D5:C1:82:D2:80:A4:69:A8:FE

Just add SHA in your firebase project and then dont forgot to download new google-services.json after that.
