Introduction to Navigation in Flutter

Navigation is a crucial part of any app, and Flutter offers a wide range of options to do it elegantly and effectively. From predefined routes to custom animations, there’s something for everyone!

Predefined Routes

Start with the concept of predefined routes. Flutter offers a navigation system based on routes, representing different screens of the app. Navigation between routes can be easily handled using the Navigator widget.

  MaterialPageRoute(builder: (context) => SecondScreen()),
);

Navigator 2.0

For more advanced control, Flutter introduces Navigator 2.0, which allows managing navigation declaratively. You can easily define a hierarchy of routes using Router and RouteInformationParser.
