I think that the functional aspect of Dart and the near-immediate mode that flutter provides are a godsend. UI in other languages is a sticky mess of callbacks and dealing with anything multithreaded is a chore. Flutter just rebuilds and rebinds everything once the state changes (you'd be surprised how fast it is!)
