Flutter custom Navigator

In Flutter these elements are called routes and they’re managed by a Navigator widget. The navigator manages a stack of Route objects and provides two ways for managing the stack, the declarative API Navigator. pages or imperative API Navigator. push and Navigator .

home. The widget for the default route of the app (Navigator. defaultRouteName, which is / ). This is the route that is displayed first when the application is started normally, unless initialRoute is specified. It’s also the route that’s displayed if the initialRoute can’t be displayed.

navigatorKey. A key to use when building the Navigator . If a navigatorKey is specified, the Navigator can be directly manipulated without first obtaining it from a BuildContext via Navigator.
