setNewRoutePath method
Called by the Router when the Router.routeInformationProvider reports that a new route has been pushed to the application by the operating system.
Consider using a SynchronousFuture if the result can be computed synchronously, so that the Router does not need to wait for the next microtask to schedule a build.
Implementation
@override
Future<void> setNewRoutePath(DartBoardPath path) async {
navStack = [DartBoardPath('/', initialPath)];
push(path.path, expanded: true);
}
