This tutorial explains how to use dynamic file-based routing in React Native using Expo Router. It is designed for beginners and intermediate developers who want to understand modern navigation systems in mobile applications.

In traditional mobile development, navigation is often handled manually by defining routes and screens. However, Expo Router introduces a file-based routing system, similar to modern web frameworks, where your file structure automatically defines your app navigation.

You will learn how to create screens using files and folders, and how Expo Router automatically maps them into routes. This makes navigation simpler, more scalable, and easier to manage in large applications.

The tutorial also explains dynamic routing, which allows you to pass parameters through URLs or routes. This is useful for creating detail screens such as product pages, user profiles, or item details. You will understand how to retrieve and use route parameters inside your components.

By the end of this lesson, you will be able to build structured navigation systems in React Native using Expo Router. You will also understand how file-based routing improves development speed and keeps your project organized, especially in larger
