How to pass data from a modal with Expo Router using React-Native

Issue

Newbie to expo-router & React-Native

I have two screens (a & b) for example, b being a modal which is presented over a.

How would I go about passing data from screen b (the modal) back to screen a?

File Structure

app
-(tabs)
--account
---index.jsx (screen a)
-create-account
--index.jsx (screen b)

Usually when you are adding a screen to the stack you would use useLocalSearchParams(); however, I am popping a screen off the stack and the screen behind is already rendered.

Solution

Figured it out. Instead of calling router.back() you can call router.push({}) with an empty pathname

Screen Receiving Data

const params = useLocalSearchParams();
const { ANY_PARAMS_HERE } = params;

Screen Sending Data

const goBack = () => {
  router.push({
    pathname: "/",
    params: {
      SOME_OBJECT: SOME_OBJECT_VALUE,
    },
  });
};
