title: how to create the tab bar without app bar in flutter?
body: <p>I wish to add the tab app instead of app bar on my home screen. How to create it. Currently, my tab bar added at the bottom of app bar and I have removed the title and elevation. At the same time,  I can't say <code>appBar: null</code> as I need some space on the top of the tab bar. </p>
  
  <pre><code>Widget HomeTap = new Scaffold(
  
  appBar: new AppBar(
  bottom: new TabBar(
  
      indicatorColor: Colors.pinkAccent[100],
      labelColor: Colors.pinkAccent[100],
      indicatorWeight: 0.5,
      unselectedLabelColor: Colors.grey[400],
      tabs: [
        new Tab(text: 'Album',),
        new Tab(text: 'Artist'),
        new Tab(text: 'Playlist'),
        new Tab(text: 'Songs'),
        new Tab(icon: new Icon(Icons.search))
      ]),
  title: null,
  elevation: 0.0,
  ),
  body: new TabBarView(
  children: [
    new Center(
      child: new AlbumWidget(),
    ),
    new Container(),
    new Container(),
    new Container(),
    new Container(),
  ],
  ),
  );
  </code></pre>
