title: show message if listview is empty react native
body: <p>If List View is empty, I would like to show the header(Which is happening) and also show a alternate Text saying "List is Empty".</p>
  
  <p>I tried doing getRowCount(), which returns 0. But how can I insert the text in the same view.</p>
