 * This hook is useful when you only want to subscribe the state of a model, but don't want to use any accessor to trigger a request.

 * @param getSnapshot
 * Return the data you want whenever the state of the model changes.
 * Make sure that this function is wrapped by `useCallback`. Otherwise it would cause unnecessary rerender.
 * @returns The return value of the `getSnapshot` function.
