Executes a simple transaction that both pops the current route off and pushes a named route into the navigator that most tightly encloses the given context.
If non-null, result will be used as the result of the route that is
popped. Routes such as dialogs or popup menus typically use this mechanism
to return the value selected by the user to the widget that created their
route. The type of result, if provided, must match the type argument of
the class of the current route. (In practice, this is usually "dynamic".)
Returns a Future that completes when the pushed route is popped.
Typical usage is as follows:
Navigator.popAndPushNamed(context, '/nyc/1776');
Source
static Future<dynamic> popAndPushNamed(BuildContext context, String routeName, { dynamic result }) {
NavigatorState navigator = Navigator.of(context);
navigator.pop(result);
return navigator.pushNamed(routeName);
}
