Enable custom validations for onLiveErrorFeedback

[CarlosRafael22]

We cannot have a different validation apart from the standard ones provided. If we want to validate more than with the min, max, etc.. functions we are not able. There should be a way to enable custom validation with the values of different fields.

PROPOSED IMPROVEMENT:

const onLiveErrorFeedback = (validate: Function) => {
    return [
      validate('firstName').uppercase().min(6, 'Must have more than 6 caracters').max(8, 'Must have 8 at most'),
      validate('lastName').lowercase().min(6, 'Must have more than 6 caracters').max(10, 'Must have 10 at most'),
      validate('lastName').custom(values => (values.lastName.indexOf(' ') > -1, 'Should have space'))
    ]
  }
