Describe the bug

Typing for "value" in Radio.Group is string | undefined, but to be able to clear value through an external element the value must be set to null.
I assume that setting the value to undefined changes the component from controlled to uncontrolled, and keeps the current state internally somehow

If possible, include a link to a codesandbox with a minimal reproduction

Possible fix

Easiest fix could be to add null as an option in the types declaration for "value" prop so it does not need to be casted in typescript?

This would make developers more certain that null can be used as a valid value in a radio button group to signal a non-selected, yet controlled value.

Self-service

• I would be willing to implement a fix for this issue
