/**
 * Prepare data for the Show view.
 *
 * useShowController does a few things:
 * - it grabs the id from the URL and the resource name from the ResourceContext,
 * - it fetches the record via useGetOne,
 * - it prepares the page title.
 *
 * @param {Object} props The props passed to the Show component.
 *
 * @return {Object} controllerProps Fetched data and callbacks for the Show view
 *
 * @example
 *
 * import { useShowController } from 'react-admin';
 * import ShowView from './ShowView';
 *
 * const MyShow = () => {
 *     const controllerProps = useShowController();
 *     return <ShowView {...controllerProps} />;
 * };
 *
 * @example // useShowController can also take its parameters from props
 *
 * import { useShowController } from 'react-admin';
 * import ShowView from './ShowView';
 *
 * const MyShow = () => {
 *     const controllerProps = useShowController({ resource: 'posts', id: 1234 });
 *     return <ShowView {...controllerProps} />;
 * };
