Summary  
This chapter explains how to use named routes to manage navigation by mapping string identifiers to widget-building functions, enabling clean, centralized route definitions and easy data passing via arguments.  

General domain of usage  
Application navigation management

**Named routes** are string identifiers that represent screens in a Flutter app. Instead of directly referencing screen widgets when navigating, you use a string name to identify the destination. This makes navigation logic more organized and easier to manage, especially as the app grows.

Definition

This video visually explains how to use named routes in Flutter navigation. You will learn how to define route names, set up the routes map in the MaterialApp widget, and navigate between screens using named routes. The video also demonstrates how to pass arguments with named routes and shares best practices for organizing your navigation logic in larger Flutter apps. By the end, you will understand how named routes make your app's navigation structure clearer and easier to maintain as your project grows.

When you use named routes in Flutter, you define a map of route names to widget builder functions in the `MaterialApp` widget. This map tells Flutter which widget to show for each route name. By centralizing route definitions, you make your navigation structure clear and maintainable.

Named routes also make it easier to pass data between screens. You can provide arguments when you call `Navigator.pushNamed`, and then extract those arguments in the target screen. This keeps your navigation logic clean and decoupled from widget construction.
