Unless they force Flutter upon Android devs, I will let it pass, not eager to learn Dart.
I think they've made it pretty clear by now that they don't have intentions of switching from Dart. Heck, they've published an entire "Why Flutter uses Dart" article explaining their reasoning.
It's like beating a dead horse.
Besides, you could always just not use Flutter if you dislike it that much.
I guarantee to you that if they had choosen a proper modern language, Flutter's uptake would be much higher.
As it is, you will see many of us complain about Dart until Flutter ends up being replaced by something else, unless they force Android developers to actually use it.
React Native uses a programming language widely accepted, no need for complains.
C# was just an example of a language that is actually worthwhile to have on a CV. I could have given many other examples.
Ad Words team rescued Dart from certain death and Flutter it is attempt to come play into the ring.
But I guarantee you'd be amazed of just how quickly you could go from installing the Flutter plugin into VS Code to actually developing a fully hot-reloaded app inside an iOS emulator. The DX of Flutter is by far the best I've seen anywhere.
So no surprises there.
