Relying on native components means that differences in platforms get propagated up into application developer land. Consider: Two "native" components have slightly different behaviours. Therefore, the framework also implicitly has two slightly different behaviours. Therefore, the developer using the framework has to cater for two slightly different behaviours. This is where the real pain of cross platform development happens, and the reason it has such a bad rep.

By bypassing the target environment's native controls, they're paying more heavily in render code, but they're getting rid of all of that propagation of pain to higher up the development stack. As a developer, that's a cost I'm willing to pay.

(* For reference, I have used Flutter, Xamarin, React Native and Java at various points in time, and Flutter has very rapidly become my preference. It has a consistency that I appreciate. But of course, ymmv.)
