I’m starting to use react native and trying to pass a setState function from one screen to another using the expo routing:

...
 const [message, setMessage] = useState(null);
...



<Pressable
  onPress={() => 
    router.push({
      pathname: "/page2",
      params: {message: message, method: setMessage},
     })
   }
...

however when I go to use the function in page2, i get the error message:

method is not a function (it is ‘function bound dispatchSetState(a0) { [bytecode]}’)

anyone know how i can pass functions between screens in react native???

alternatively how do you go about changing the state in a homescreen from a screen further down the stack.

All help and advice is greatly appreciated! 🙂

I tried passing the function in to the params object like a variable but got an error
