I don’t know enough about the details of react native, but I would consider them and flutter to be native, i don’t think there’s an interpreter in either case ?

There’s not, but flutter renders everything to a skia canvas, instead of using native controls. I guess it has the advantage of pixel perfect rendering on any platform, but it misses out on control styles being updated, and the optimization of the OS.
React native uses native apis for everything except telling the OS where to draw them. It feels a bit more native than flutter in that regard to me.
