Manage multi-steps form (with validity check flow) and watch errors without re-rendering whole form

[moulinraphael]

Hey everyone !

For a personal project, I needed to :

• handle multi-steps form (with some check on the validity of step's fields)
• view errors live (without re-render because in the current API, errors are inside formState)

So, I implemented a draft to manage these points. It's not perfect and I do not have a lot of time to spent but it could be interesting for some of you or maybe for some future features of this great lib (thanks the team and @bluebill1049 )

Let me know if you have any comment, suggestion :)
