28% of new iOS apps are made with flutter and it's the #1 cross platform framework on stack overflow 2024 survey so I highly doubt it has flatlined.

All those stats look great on paper, but a few months ago I checked job postings for different mobile frameworks, and Flutter listings were 2-3 times fewer than RN. Go on Indeed and see for yourself.
For a "28% of new iOS apps", the Flutter subreddit is a ghost town with regular "is it dying? should I pick RN?" posts. I just don't buy the numbers because I'm myself in a rather stagnant cross-platform ecosystem, so I know this vibe well.
If I ever leave .NET, no way I'd move to something like Flutter. Even Kotlin Multiplatform is more promising concept-wise. LLMs are changing cross-platform development and Flutter's strong sides are not that important anymore, while its weak sides are critical.
Maybe you are just not in the target market? I just checked FlutterShark and I have 14 apps installed with flutter in it.
Flutter is starting to become the default framework to build apps in in Asia at least.
And I disagree about the LLM, Flutter provides strong standardisation and strong typing which make it an ideal target for LLM.
As for Kotlin Multiplatform, maybe it will take off similarly as Flutter but that hasn't happened yet.
