Externally determining if form has errors

Description

Honestly this is just quick question that I didn't find in searching first. Being that I'm not using submit button because of displaying a form in a dialog and wanting to use submit button of my modals, I'm curious what the best way to determine whether the form was in a "good" state... rather that validation is passing.

I know I can provide a onChange callback, and get at e.errors. Would the best way of providing the state to my modals button be to set a state variable isValid to e.errors.length> 0 and then use that as whether my button is enabled/disabled?

Is there a better way to get at that more directly? Appreciate any feedback.

should an easy change, if you want to make a PR, to include this functionality, please do. Possibly another callback called isValid could be added that we can called to check state of the form. regarding the submit button, I have a PR that will give more flexibility to hide the button. Read only forms will then be a possibility and change the text

Are you able to get something like e.errors using React v17? I'm only getting undefined

onChange={
            (formData, e) => {
              console.log("Event:", e)
            }
          }

e is undefined
