An ability to check is form valid or not

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

For e.g. I want to display a form for user and be able to toggle an disabled prop of submit button if form is valid or not.

What does the proposed API look like?

It would be super if it would be possible to do by using accessing this boolean value like a form prop like:

this.props.form.isValid

Is there a way to validate the form like validateFields() that does not end up showing error messages next to the form fields?

I am trying to continually know whether the form is valid or not and disable the submit button accordingly.

In my case, I use the Form within a Modal and the submit of the form is done with the button in the footer of the Modal, therefore to know if the Form is valid I use the following:

const [form] = Form.useForm()

const isFormValid = () => form.getFieldsError().some((item) => item.errors.length > 0)
