title: Change height of AppBar
body: <p>I am developing a Flutter app. In this app I have used TabBarController in app bar. I am not using icons and title for AppBar so height is showing me more than expectation. I need help to do this with desired size. I am using following code:</p>
  
  <pre><code>class Dashboard extends StatefulWidget{
    @override
    State&lt;StatefulWidget&gt; createState() =&gt; new _DashboardState();
  }
  
  class _DashboardState extends State&lt;Dashboard&gt; with SingleTickerProviderStateMixin{
  
    final List&lt;Tab&gt; myTabs = &lt;Tab&gt;[
      new Tab(text: 'page1.',),
      new Tab(text: 'page2.'),
    ];
  
    TabController _tabController;
  
    @override
    void initState() {
      super.initState();
      _tabController = new TabController(length: 3, vsync: this
      );
    }
  
    @override
    void dispose() {
      _tabController.dispose();
      super.dispose();
    }
  
    @override
    Widget build(BuildContext context) {
      return Scaffold(
        appBar: new AppBar(
          bottom: new TabBar(
            indicatorSize:TabBarIndicatorSize.tab,
            controller: _tabController,
            tabs: myTabs,
            labelStyle: styleTabText,
  
          ),
        ),
        body:  new TabBarView(
          controller: _tabController,
          children: myTabs.map((Tab tab) {
            return new Center(
                child: new Text(
                    tab.text
                )
            );
          }).toList(),
        ),
      );
    }
  }
  </code></pre>
  
  <p>Also for reference I am adding screenshot of app.
