Question: RadioGroup - Missing state / description props

[sebsobseb]

I noticed that, unlike the TextField and TextArea components, the RadioGroup component doesn’t support state and description props for showing an error state and message.

When reviewing the RadioGroup docs, imagine a scenario where selecting one option is required. In that case, we’d need to display an error message if the user doesn’t make a selection and submits the form.

Is there an alternative way or UX pattern to handle this that I might be overlooking? Or is state and description something that should be added to the RadioGroup component?
