there are developers who are just happy to write the same logic in multiple languages, and there are those who find it extremely mind-boggling, this is regardless of how nice/easy to learn those languages are.
Nobody is happy to write the same logic in multiple languages. There are other ways to package logic and have it be consumable by multiple teams building native mobile apps for various platforms. If you are trying to solve this by very specific problem by adopting something like React Native or Flutter then I would question many other things beyond this.

Really what way? Make a backend endpoint? Convert to C++ and invoke as native code? I'm only speaking for react native it's more than sharing code it's sharing skill, a web/nodejs dev can learn it and jump on company's mobile app when needed, as opposed to have dedicated devs for Android and iOS who sit around doing nothing sometimes and stop company from shipping when they go on vacation.
