iOS Integration

Make sure you have GoogleService-Info.plist with CLIENT_ID

Add REVERSED_CLIENT_ID as url scheme to Info.plist

Android Integration

Inside your strings.xml

<resources>
  <string name="server_client_id">Your Web Client Key ( Same as the one in the index.html meta tag )</string>
</resources>

Import package inside your MainActivity

import com.hristo2612.capacitor.google.auth;

Register plugin inside your MainActivity.java

public class MainActivity extends BridgeActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        registerPlugin(GoogleAuth.class);
    }
}

Configure

Provide configuration in root capacitor.config.json

{
  "plugins": {
    "GoogleAuth": {
      "scopes": ["profile", "email"],
      "serverClientId": "xxxxxx-xxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
      "forceCodeForRefreshToken": true
    }
  }
}

Note : forceCodeForRefreshToken force user to select email address to regenerate AuthCode used to get a valid refreshtoken (work on iOS and Android) (This is used for offline access and serverside handling)
