/**
* This is a helper function for when a component needs to be able to forward a ref
* to a child component, but still needs to have access to that component as part of
* its implementation.
*
* Its main use case is in wrappers for native components.
*
* Usage:
*
* class MyView extends React.Component {
* _nativeRef = null;
*
* _setNativeRef = setAndForwardRef({
* getForwardedRef: () => this.props.forwardedRef,
* setLocalRef: ref => {
* this._nativeRef = ref;
* },
* });
*
* render() {
* return <View ref={this._setNativeRef} />;
* }
* }
*
* const MyViewWithRef = React.forwardRef((props, ref) => (
* <MyView {...props} forwardedRef={ref} />
* ));
*
* module.exports = MyViewWithRef;
