Flutter/Dart, yes, React Native/Javascript, no. With RN the app's code runs via an embedded JavaScript engine, and even when, say, Hermes is being used, it's still executing bytecode not native machine code.

Also important to note that any code that runs on Android's ART runtime (i.e. Kotlin and/or Java) can get some or all of its code AOT-compiled to machine code by the OS, either upon app install (if the app ships with baseline profiles) or in the background while the device is idle and charging.
