title: How clear focus for BasicTextField in Jetpack Compose?
body: <p>I have a Jetpack Compose (Beta04) BasicTextField (with decorationBox). How can I clear the focus?</p>
  <p>I have tried with focusRequester but this doesn't works:</p>
  <pre><code>val focusRequester = remember { FocusRequester() }
  
  // ...
  
  BasicTextField(modifier = Modifier.focusRequester(focusRequester), /* ... */)
  
  // ...
  
  placesFocusRequester.freeFocus()
  </code></pre>
