title: show FlatList ItemSeparatorComponent when no data exist
body: <p>I want to show <code>FlatList</code> like this ,each item renderer has a <code>ItemSeparatorComponent</code> even if there is no data for them.</p>
  
  <p>I guess I can add empty data to the <code>dataProvider</code>.</p>
  
  <p>And I want to know if I can set some attributes of <code>FlatList</code> to make it work?</p>
