Angular Dart stepper

Question

I'm having issues with the Material Stepper for Angular Dart, I was trying to put it into my own app but just to test I copied the entire demo from :

https://github.com/dart-lang/angular_components/blob/master/examples/material_stepper_example/lib/material_stepper_demo.dart

The issue is whenever I try to load that component I get this error EXCEPTION: No provider found for DomService: ScrollHost -> DomService.

As I said im getting that error with the working demo code, if anyone can assist that would be great.

Similar to https://github.com/dart-lang/angular_components/issues/288

The list item needs DomService which is an injectable.

The easiest way to get it is to add the materialProviders to your root. You can see that here: https://webdev.dartlang.org/codelabs/angular_components/2-starteasy#--set-up-the-root-components-dart-file

Thanks for using angular_components.

Make sure scrollHostProvider is in your @Component():

providers: [scrollHostProviders]
