When the flow starts, the browser opens, I select an account, and it keeps showing:

"""
Page not found
The page you're looking for doesn't exist.
general_route_not_found
"""

Although the message remains displayed in the browser, the user appears in the Console.

The URL is: https://nyc.cloud.appwrite.io/console/auth/oauth2/success?project=the-recipes&domain=.nyc.cloud.appwrite.io&key=a_session_the-recipes&secret=

Dart

import "package:appwrite/enums.dart" as enums;

Future<void> signInWithGoogle() async {
  try {
    EasyLoading.show(status: "auth_controller.signing_in".tr);

    await _account.createOAuth2Session(
      provider: enums.OAuthProvider.google,
    );
    
    await _checkCurrentUser();
    
    EasyLoading.dismiss();
  } on AppwriteException catch (e) {
    EasyLoading.dismiss();
    print("Appwrite error: ${e.code} - ${e.message}");
    EasyLoading.showError("auth_controller.sign_in_error".tr);
  } catch (e) {
    EasyLoading.dismiss();
    print("General error: $e");
    EasyLoading.showError("auth_controller.sign_in_error".tr);
  }
}

Summary

Issue: The Flutter OAuth2 Google process does not redirect back to the mobile app and displays a 'Page not found' error. Solution: - Check the AndroidManifest.xml file for the correct configuration for CallbackActivity. - Ensure the pubspec.yml includes the correct version of the appwrite package. - Review the Dart code for any errors or misconfigurations in the signInWithGoogle function.
