# Navigation and Routing sample code
Sample code for [Learning Flutter's New Navigation and Routing System][article],
an article explaining the Router widget and its associated classes.
## Samples
**Navigator samples**
* [navigator/anonymous_routes.dart](lib/navigator/anonymous_routes.dart) -
Shows how to use a Navigator to push and pop anonymous routes (e.g.
MaterialPageRoute)
* [navigator/named_routes.dart](lib/navigator/named_routes.dart) - Shows
how to use define named routes via the `routes` parameter on MaterialApp, and
navigate using Navigator.pushNamed
* [navigator/on_generate_route.dart](lib/navigator/on_generate_route.dart) -
Shows how to handle arbitrary named routes using the `onGenerateRoute`
callback defined in the `MaterialApp` constructor.
**Router samples**
* [router/pages.dart](lib/router/pages.dart) - Shows how to define a list of
[Page] objects on Navigator declaratively.
* [router/router.dart](lib/router/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**
* [router_advanced/nested_router.dart](lib/router_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.
* [router_advanced/transition_delegate.dart](lib/router_advanced/transition_delegate.dart)
Shows how a custom TransitionDelegate can be used to customize when
transition animations are shown.
