Ability to check if a form is valid without having to display the errors/feedback on the UI (leveraging formInstance.validateFields)

[chandu]

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

What problem does this feature solve?

The FormInstance has a method validateFields: (nameList?: NamePath[]) => Promise which can be used to check if a field/all fields of the form are valid or not. This also updates the UI to display error messages/feedback on the form.
However there could be use cases where we just need to know if the form is valid or not without displaying any feedback/errors. (e.g: displaying form for the first time with pre-populated data from external source etc.)

As an example @ the CAB https://codesandbox.io/s/bitter-frost-btmsy
When I click on the Validate button, I would like to know if the form is valid or not without showing the errors/feedback on the UI.
But right now the this is not possible.

This can be useful to let's say enabling/disabling Submit button etc.

What does the proposed API look like?

May be we can add an option/flag to the validateFields to allow checking the form is valid or not without any UI errors/feedback.

e.g: validateFields: (nameList?: NamePath[], options?: { showErrors?: boolean }) => Promise
