Angular 2.0 Dart with Transformer and Router

Question

Running into an weird issue when I use Angular 2.0 Dart. Basically I'm trying to use Router and using pub serve to transform it to JS using the angular transformer. However I get the following error

Cannot find reflection information on RouteRegistry
    at dart.wrapException (http://localhost:8080/main.dart.js:2834:17)
    at NoReflectionCapabilities.dart.NoReflectionCapabilities.factory$1 (http://localhost:8080/main.dart.js:31991:17)

But removing the transformer

- angular2:
    entry_points: web/main.dart

I can see my app and navigate through the routes properly, however the downside is that my Dart2JS file is now 2.8megs

Answer 1

Currently as of Alpha 28, this is not supported. Alpha 30 will have this fixed.

Answer 2

You could add "mirror_mode: verbose" to the angular2 transformer.

Answer 3

Does RouteRegistry come from a different package? If so make sure the angular transformer has also been added to that package (it doesn't have to specify any entry points). The new angular transformer works a lot differently than the old one and it is required on all packages, not just the application package.
