React Native how to get element position inside panresponder

Question

I'm trying to return the values of .measure but it seems the code inside can't interact without using a state, and so it keeps returning false. I'm trying to avoid using a state because I need the value inside my PanResponder

Measure function returns false

 const showRefPosition = assignedRef => {
    let maxHeight = false;

    assignedRef.measure((x, y, width, height, pageX, pageY) => {
      const maxY = SCREEN_HEIGHT - height;

      maxHeight = pageY - maxY < 40;
    });
    console.log("new maxHeight", maxHeight);

    return maxHeight;
  };

What I'm trying to do: is to get the elements position inside the PanResponder

My problem

I'm trying to get the elements position inside the PanResponder, but keep getting the wrong value (default value). Or the state inside the PanResponder doesn't update.

PanResponder

  const panResponder = useRef(
    PanResponder.create({
      onMoveShouldSetPanResponder: (event, gestureState) => {

        console.log("showRefPosition", showRefPosition(this.AnimatedRef));
        if (event.nativeEvent.pageY < 100) {

          pan.flattenOffset();
          Animated.spring(pan, {
            toValue: { x: 0, y: -600 },
          }).start();

          return false;
        }
        return Math.abs(gestureState.dy) > Math.abs(gestureState.dx * 3);
      },
