What

The current Field API supports setting a field as required:

{
  id: 'someField',
  isValid: {
    required
  }
}

This comes with some handy marker in the field label:

However, there are situations (e.g., most fields are required) where we don't want to signal the "required" fields, but rather the "optional" ones. This is supported by the underlying components via a markWhenOptional flag:

What is your proposed solution?

There are a few avenues we could explore:

• Add a markWhenOptional prop to Edit, like we have hideLabelFromVision.
• Configure the isValid.required to accept values other than boolean that codify how the label is rendered (add required or optional). For example,

{
  isValid: {
    required: {
      value: true | false,
      label: 'whenOptional' | 'whenRequired'
    }
  }
}
