title: Flutter navigation to TabNav page from other page
body: <p>I have a bottomNavigation Bar with a TabBarview as below:</p>
  
  <pre><code>@override
    Widget build(BuildContext context) {
      return new Scaffold(
        //drawer: _drawer,
        appBar: new AppBar(automaticallyImplyLeading: false,
            title: new Text(_choice.title), actions: getAppBarActions(context)),
        bottomNavigationBar: new Material(
            color: CupertinoColors.lightBackgroundGray,
            //color: c,
            child: new Container(
              height: 50.0,
              child: new TabBar(
                controller: controller,
                //labelColor: Colors.grey,
                tabs: mytablist,
                labelStyle: new TextStyle(fontSize: 10.0),
                labelColor: CupertinoColors.activeBlue,
                unselectedLabelColor: CupertinoColors.inactiveGray,
                isScrollable: true,
                indicatorWeight: 1.0,
                indicatorColor: CupertinoColors.activeBlue,
                //indicatorPadding: new EdgeInsets.only(bottom: 5.0),
              ),
            )),
        body: new TabBarView(
          controller: controller,
          children: _tabWidgets(),
        ),
      );
    }
  </code></pre>
  
  <p>I have of courses pages that are navigated to, I also navigate to pages off the tabbarview that do not have the bottomnavigation, however I want to be able to navigate to one of the pages within the bottomnav, but when I do using something like this:</p>
  
  <pre><code>Navigator.of(context)..pushReplacementNamed(Chat.ChatServerPage.routeName);
  </code></pre>
  
  <p>It goes to the page but without the appbar or the bottomnavigationbar, anyone know how to accomplish this?  I have tried all that I could find. Any help would be appreciated.</p>
