Navigation and Routing sample code

Sample code for Learning Flutter's New Navigation and Routing System, an article explaining Navigator 2.0.

Samples

Navigator 1.0 samples

• nav_1/anonymous_routes.dart - Shows how to use a Navigator to push and pop anonymous routes (e.g. MaterialPageRoute)
• nav_1/named_routes.dart - Shows how to use define named routes via the routes parameter on MaterialApp, and navigate using Navigator.pushNamed
• nav_1/on_generate_route.dart - Shows how to handle arbitrary named routes using the onGenerateRoute callback defined in the MaterialApp constructor.

** Navigator 2.0 samples**

• nav_2/pages.dart - Shows how to define a list of [Page] objects on Navigator declaratively.
• nav_2/router.dart - Full sample that shows a custom RouteInformationParser and RouterDelegate parsing named routes and declaratively building the stack of pages for the Navigator.

** Advanced **

• nav_2_advanced/nested_router.dart - Shows two [RouterDelegate], one nested within the other. A [BottomNavigationBar] can be used to select the route of the outer RouterDelegate, and additional routes can be pushed onto the inner RouterDelegate / Navigator.
• nav_2_advanced/transition_delegate.dart - Shows how a custom TransitionDelegate can be used to customized when transition animations are shown.
