title: How to create standard Borderless buttons (like in the design guideline mentioned)?
body: <p>I was just checking the design guidelines and wondering about the borderless buttons.
  I goggled and tried to find in the source but can't bring it together by myself.
  Is this the normal Button widget but you add a custom (Android default) style?
  How to make these borderless buttons (of course you can set the background to empty, but then I don't have the divider)?</p>
  
  <p>Here links to the design guidelines:</p>
