Flutter confuses me. Its annoying you have to use their DSL for layouts rather than HTML and what about native widgets, like WebViews or VideoPlayers?
With them drastically speeding up the Dart2JS compiler and implementing a strong typed mode, I am quite pleased with Dart's direction.
I do still fear for its future. It would be really to sad to see Dart die. The last web app I made, I was able to make the entire thing in under 90kbs, including HTML, CSS, SVGs, and JS. Dart allows me to write desktop like applications for the web with any extra overhead.
