I tried out flutter in the past few weeks and it seems really great, especially compared to the android framework. Dart also seems to fit in really well. But I do have some criticism for dart. While it's nice that they moved to a static types, they still made every single type nullable. So e.g. if you get a boolean in your function, be aware that it can be true, false and also null. I have my problems with java having nullable objects, but having the primitives also be nullable? Well, I'm pretty much a beginner, so maybe there are better ways and I still don't know them. But afaik, they weren't mentioned in the brief Dart intro on the flutter page. Dart does also have some cool things, though: Extensions (for adding interfaces to existing types), explicit getters, async/await and lots of syntactic sugar. Building your widget-tree in dart sometimes looks like a declarative style similar to xml, but far more concise, except that it's really imperative, which is really cool. No long Component a = new Component(); a.setOnClickHandler(xyz); a.setColor("green"); b.add(a); chains anymore!
