/**
 * Measures child element size and it's screen position asynchronously.
 * Returns measure result in `onMeasure` callback.
 *
 * Usage:
 *
 * ```tsx
 * const onMeasure = (frame: Frame): void => {
 *   const { x, y } = frame.origin;
 *   const { width, height } = frame.size;
 *   ...
 * };
 *
 * <MeasureElement
 *   shouldUseTopInsets={ModalService.getShouldUseTopInsets}
 *   onMeasure={onMeasure}>
 *   <ElementToMeasure />
 * </MeasureElement>
 * ```
 *
 * By default, it measures each time onLayout is called,
 * but `force` property may be used to measure any time it's needed.
 * DON'T USE THIS FLAG IF THE COMPONENT RENDERS FIRST TIME OR YOU KNOW `onLayout` WILL BE CALLED.
