The code is very long but this is the best example i can give for clarifaction:

const focus = useCallback(async () => {
await core.delay(10)
titleRef.current?.setNativeProps({
hasTVPreferredFocus: true,
})
}, [focusStore.screen])I have a Card component, and its rendered many times in the app, i want the Card components to run the focus function every time the
[focusStore.screen] changes, but when i do this i useEffect, it runs like 100 times and is not performant at all
