That's an interesting experiment. The demo is extremely underwhelming though. I have to wait ~5 seconds for each screen to load, while on a wifi network. I don't know if it is dues to Dart framework or the http code loading, but it is way too high to be acceptable. The stocks app demo is a trivial exemple. A simple list with nothing else except for a nav drawer. It is very fluid but also extremely barebone.

Same thing for the square spinning at 60 fps. Call me back when there are 1000 of these.

Don't get me wrong, it is a very interesting experiment but it is hard to get excited for something so limited.
