Missing ref in functional components

[diegofiore83]

👋 Hello 👋
I noticed that latest version of the library export functional components instead of class component. With this change the ref passed become undefined and solutions like the following are not anymore possible.

<MTableToolbar {...props} ref={toolbarRef} />

toolbarRef.current.onSearchChange(search);

Maybe considering something like this for future release could repristinate that functionality: https://levelup.gitconnected.com/react-refs-for-function-components-44f1a5a2332a

Thoughts?
