This tutorial concludes a seven-part series on integrating Google login into an iPhone app using Expo, Metro, and Clerk. The final step implements a logout function in a protected route, calling Clerk's `signOut()` method and redirecting users to the home screen. The code handles errors and uses Expo Router's navigation for a smooth user experience.

The series guides developers through setting up a Clerk project, configuring API keys, and structuring an app with Expo Router's file-based routing. Using a protected.tsx page with a guard ensures only authenticated users access sensitive content. This approach provides a complete authentication flow, from login to logout, using modern React Native and backend-as-a-service tools.

For developers building mobile apps, this demonstrates a practical pattern for managing user sessions. The full source code is available on GitHub, offering a template for integrating third-party auth. Future tutorials from the author may cover using AI tools for development and deploying production-ready applications.
