title: Flutter/Dart: Customize Bottom Navigation Bar height
body: <p>Is there a way to customize <code>BottomNavigationBar</code>'s height?</p>
  
  <p>I currently have a <code>BottomNavigationBar</code> with tabs to taps/swipe navigate, however the default height (even after reducing the text and icon) is too high.</p>
  
  <pre><code>@override
  Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      backgroundColor: Colors.blue,
      title: Text( 'RefLog', style: Styles.headerLarge ),
      actions: &lt;Widget&gt;[
        new IconButton(
          icon: Icon(Icons.list),
          onPressed: () {},
        )
      ],
    ),
    body: DefaultTabController(
      length: 3,
      child: Scaffold(
        body: TabBarView(
          children: _children,
        ),
        bottomNavigationBar: TabBar(
          tabs: [
            Tab( text: 'One', icon: Icon(Icons.import_contacts, size: 20.0) ),
            Tab( text: 'Two', icon: Icon(Icons.restaurant, size: 20.0) ),
            Tab( text: 'Three', icon: Icon(Icons.record_voice_over, size: 20.0) ),
          ],
          labelStyle: TextStyle(fontSize: 12.0),
          labelColor: Colors.white,
          unselectedLabelColor: Colors.white30,
          indicatorSize: TabBarIndicatorSize.label,
          indicatorColor: Colors.white,
        ),
        backgroundColor: Colors.blue,
      ),
    ),
   );
  }
  </code></pre>
