Navigator 1.0 vs Navigator 2.0 in Flutter

Navigator 1.0 vs Navigator 2.0 in Flutter

🚀 Introduction

Flutter provides two approaches for navigation: Navigator 1.0 (imperative) and Navigator 2.0 (declarative). Let's compare them!

🔹 Navigator 1.0 (Imperative Navigation)

• Stack-based navigation (push/pop)
• Simpler API, great for small apps
• Uses MaterialPageRoute or CupertinoPageRoute
• Limited support for deep linking

Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => SecondScreen()),
);
            

🔹 Navigator 2.0 (Declarative Navigation)

• Declarative navigation using Router
• Better for web and deep linking
• Uses RouteInformationParser and RouterDelegate
• More control over navigation state

MaterialApp.router(
  routerDelegate: MyRouterDelegate(),
  routeInformationParser: MyRouteInformationParser(),
);
            

🧐 When to Use Which?

✅ Use Navigator 1.0 for simple apps with basic navigation.

✅ Use Navigator 2.0 for apps requiring deep linking, web support, or dynamic navigation.
