I wrote a small Flutter app recently and rather enjoyed the experience. I'm reluctant to spend more time on the technology, though, since it seems like it has a high chance of dying out. But as I understand it, Fuchsia would have native apps written using Flutter as well, which would be great, so I really hope it does take off.
I think it's more of an issue with it coming from and being maintained by Google. I think aversion to Dart is overrated; it's a boringly stable and straightforward language, and I'm puzzled that mobile developers aren't more open to learning it, given how Objective-C/Swift/Kotlin were languages that most had to learn for developing on their respective smartphone.
