AngularDart CurrentInstruction

I am trying to update angular2 to latest version. Several of the functions are missing

I would like to know what is the alternate for the following function

final RouteParams _params;
String get routeName => _router.currentInstruction.component.routeName;

How to get routeName from new AngularDart

Not possible to access current component route anymore.

I don't know what you want to do exactly and how you define your routeName, but you probably need to use additionalData of RoutePath or RouteDefinition

class AdditionalRouteData {
  final String routeName;

  const AdditionalRouteData({this.routeName});
}

final routePath = RoutePath(
    path: '/',
    additionalData: AdditionalRouteData(routeName: 'Home'),
);


// then get it that way
(router.current.routePath.additionalData as AdditionalRouteData).routeName;

However, if your routeName is dynamic, you must find a new way to access it (without the router, using a service via dependency injection)
