## Functional specs
* The `error` prop overwrites the `help` prop, due to higher priority.

* The color of the label will turn into cloud shade when the Textarea has some filled value.

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

  constructor() {
    super()
    this.ref = React.createRef();
  }
  
  componentDidMount() {
    this.ref.current && this.ref.current.focus();
  }

  ref: { current: React$ElementRef<*> | null };

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