X vs Y thing is always fun to read. We would all agree that Native apps are still better than RN and Flutter ones. So choosing either platform is a decision you need to take whether you want something fast and compromise on few thinks like look and performance or you want something solid. Secondly the issue with flutter is Dart. If you're a startup with 3 guys, working on Go lang for backend APIs, React / Svelte for frontend would you rather choose Js / TS for your app development or Dart. The whole time taken to build X using Y goes for a toss here. I would rather keep minimum moving parts if I'm small. If you're an enterprise and you've got resources you can experiment with Flutter + Dart, work for 2 years and when the project gets shelved ( just like other Google projects ) start migrating to Native or Js. After that you'll question yourself why did I learn Dart in the first place ? Did Flutter provide enough features that React Native didn't, etc.
