## Functional specs
* The`hasError` prop will be visible only when the Radio has `checked` or `disabled` prop set on false.

* `ref` can be used for example auto-focus the elements immediately after render.
```jsx
class Component extends React.PureComponent<Props> {

  componentDidMount() {
    this.ref.current && this.ref.current.focus();
  }

  ref: { current: React$ElementRef<*> | null } = React.createRef();

  render() {
    return (
      <Radio ref={this.ref} />
    )
  }
}
```
