Only for the crowd, I need point out that no one's arguing there's more Dart jobs than C#.

Re: multiple frameworks, I worked at Google and would argue I know as much as anyone does exactly what happened there, so I can't agree it's weird, per se. Handwaving, I'd say that's because the situation seems more 'certain' or 'settled' to me, for good reasons, but ones not worth getting into.

There's absolutely tons of threads to unpack in your comment, I wish we were in person.

Speaking generally, based on observation you gravitated most towards discussing qualities of a job one might or might not get:

I essentially left my job at Google for no paycheck, partially because Google x Koyaanisqatsi, partially because I just couldn't imagine having to go back to write Kotlin and/or Java day to day and being criticized either way. That being said, it's deflating seeing Flutter job listings after getting into this whole industry from iOS dev. Thing with Flutter jobs is there's tons of low priced job seeking competition that are smart as hell.

That's because it is unusually effective in environments where people can't afford a Macbook only for iOS dev, and at this point in its lifecycle, it self selects for people who get experience with new frameworks
