I like how easy it is to build applications using dartlang as my backend for android app development! It's very simple compared to other languages which makes learning new things easier in comparison (I'm talking about javascript).
Since this was just an experiment of mine so far nothing really but if there are more features coming out that can be used by developers then definitely give them some time because they will come up quite fast once their popularity increases! There isn't anything at present since its still early days yet we have been able solve our problems easily without any issues or bugs encountered during testing phases etc.. So no complaints here :D As long as your looking forward into developing something cool i would say go ahead and try building apps from scratch :) The only thing left now when trying out mobile application programming through java/kotlin/dart lang could possibly use better documentation than what comes along while reading articles online regarding these topics. Try giving yourself free hands &.
