Framework like Flutter or React Native can never replace native technologies, Both platform launches their features onto their official framework and Flutter or React Native adopt these new feature via their community support that so you might need to wait or you can write on your own. Also performance is a great factor if your are more focused on performance then it's always advised to go with native on. One of the emerging technology is Kotlin Multiplatform you can try this one if you are building app for both platform. KMM can help you to put all you business logic at single place and can construct UI on the native language.

Still if you wanna move toward the Flutter or React Native my advice is to go with Flutter cause of it's increasing community support & industry choice.

We also had the same discussion, but ended with Flutter cause of it's great community support & great set of packages. Also achieving calling native feature is super smooth. And Flutter support Web as well while React Native don't. Learning curve is also a great point to choose flutter all doc's official videos are super rich to help you out.

Good thing about a programming language is ease of development & that's what Kotlin gave us. Less Boilerplate code powerful Extensions Function simplicity of Coroutines and the list goes on. Shifting from Java to Kotlin leads into reducing 50% less code & saving time.

We did a lot of POC on this topic, Had multiple discussion between our developer a lot of R&D , Then we made our mind. Flutter community is going better day by day, and a support of calling native code is going to help you achieving anything that you can't do in flutter. Hot Reload is really hot. And one of the good reason is it's web support.
