🐛 Bug Report: Google Auth screen not closing after authentication

[TanmayOG]

👟 Reproduction steps

1. Run the app on an Android 14 device.
2. Initiate the Google authentication flow using the googleAuth() function.
3. Complete the authentication process.

Dart Code:

Future<void> googleAuth() async {
  try {
    await AppwriteService.account.createOAuth2Session(
      provider: OAuthProvider.google,
    );
    loadUser();
  } on AppwriteException catch (e) {
    handleAppwriteException(e);
  } catch (e) {
    print('An unexpected error occurred: $e');
  }
}

XML:

<activity android:exported="true"
          android:name="com.linusu.flutter_web_auth_2.CallbackActivity">
          <intent-filter android:label="flutter_web_auth_2">
              <action android:name="android.intent.action.VIEW" />
              <category android:name="android.intent.category.DEFAULT" />
              <category android:name="android.intent.category.BROWSABLE" />
              <data android:scheme="appwrite-callback-[PROJECT-ID]" />
          </intent-filter>
</activity>

👍 Expected behavior

• The authorization screen should close automatically after successful authentication.

• User creation with OAuth should succeed without any errors.

👎 Actual Behavior

1. The Google authorization screen remains open after authentication, requiring manual closure.

2. The AppwriteException document_invalid_structure is thrown with the message:

Error creating user with OAuth: AppwriteException: document_invalid_structure,
Invalid document structure: Unknown attribute: "userId" (400)

@TanmayOG, thanks for creating this issue! 🙏🏼 Are you using Appwrite Cloud or self-hosting Appwrite?

In the XML you shared, the project ID isn't filled in:

<data android:scheme="appwrite-callback-[PROJECT-ID]" />

Did you replace the placeholder with your project ID?

[TanmayOG]

Yes, I'm using the project ID but it is still not working

[patialashahi31]

I am not sure if it is a similar issue, But yes I am manually closing the consent screen and it doesn't redirect back to the app

[stnguyen90]

@TanmayOG, do you have android:taskAffinity="" in your Android manifest? Maybe you can try removing it.

I'm having a similar issue where it redirects back to the app correctly, but the Google sign in screen is still open and "loading" behind the app. So when I close the app or go to recent apps on the phone, the window is still there.

Jk, just needed to add

options: const FlutterWebAuth2Options(
  preferEphemeral: true, // iOS
  intentFlags: ephemeralIntentFlags, // Android
)

Better documentation would be great for the available options and what they do.

Put it where you're triggering the auth and creating the FlutterWebAuth2 instance. It's a config option.

final authUrl = '${_dio.options.baseUrl}/auth/google';
      _logger.info('Initiating OAuth with URL: $authUrl');
      _logger.info('Callback URL scheme: deepLinkURLSchemeHere');

      final result = await FlutterWebAuth2.authenticate(
        url: authUrl,
        callbackUrlScheme: 'deepLinkURLSchemeHere',
        options: const FlutterWebAuth2Options(
          preferEphemeral: true,
        ),
      );
      _logger.info('Auth callback received: $result');

      final uri = Uri.parse(result);
      _logger.debug('Query parameters: ${uri.queryParameters}');
