Classic HN comment with unapologetic statements. If Flutter were that good, it wouldn't have flatlined so fast after the initial hype a few years ago. I tried it last year, only to see rendering glitches in the sample project.
Personally I've done a 50k+ line project in Flutter and I didn't hit any of these. There's been a few issues for sure but nowhere near what I experienced with React Native (and don't start me on native itself)

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.
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.
