ref.current returns null or undefined #375

Dev Env: EXPO - WEB useRef followed by assigning ref to Picker returns null or undefined ( however it was initialized ).

Originally, I was trying to disable the left and right arrows from changing the picker values. Decided to see if ref use will somehow help only to find ref is not being set.

example code: const r = React.useRef(); useEffect(() => { console.log(r.current); //remains undefined here }, []);

. . . <Picker ref={r} selectedValue={userFilter} style={{ width: 150 }}
