Tools will appear such as PhoneGap , where you can write Dart, compile JS, and then use it to convert it all to a native application. The question is whether it really costs - I never tried, but I could imagine that with Dart you would need to use JS-Interop widely, if it works at all at all - the tool might not even use Dart-optimized JS. In any case, if you really want to do this, it might be worth a try.
