Overview

This codelab sets the foundation for mastering navigation in Flutter. We start by examining the imperative mess that was Navigator 1.0, the over-engineered complexity of Navigator 2.0, and how go_router was born as a solution for apps that demand performance, maintainability, and deep-linking support. You'll walk away with a working multi-page Flutter app using go_router, a clear understanding of when to use it, and architectural tips that most tutorials overlook. This is not a “hello world” tutorial. This is navigation for engineers who build real apps for millions.
