Right now Fletch looks pretty awkward/painful to use though. Writing views completely natively (ObjC/Swift/Java) and then calling into a DartVM for business logic doesn't sound like a fun way to develop to me. I could be wrong, I haven't tried to use Fletch - just read some examples, but right now I don't see the benefit.
Sky is basically Cordova as far as I can tell. It dumps native looking views into a webview and calls it a day. The demo app on Google Play (https://play.google.com/store/apps/details?id=org.domokit.sk...) does not make me terribly excited for it :(
Also, looks like they will name it as Flutter: https://flutter.github.io/getting-started/
