I like your post since it's a refreshing take on today's language and framework decisions. Usually people go for Coffee, Node, Go, Clojure or ClojureScript nowadays (I mixed FE and BE tech deliberately).

What I am interested in: Why did you go for Dart? What was the trigger? When I look at Google Trends Dart seems to have a very hard time compared to other current technologies regarding search popularity.

And what's your backend based on? Could I go for Dart with Node?
