I have a PageView to show 4 pages and a BottomNavigationBar to switch them. I'm having troubles with the PageController.

In any page, I navigate to a new Screen, but when get back, the PageView return to the initial page and no to the last page.

Here is how I using the PageView

@override

void initState() {

  super.initState();

  _page = 0;

  _pageController = PageController(keepPage: true);

}



return Scaffold(

  appBar: AppBar(

      title: getAppBarTitle(_page),

      centerTitle: true,

      actions: renderActions(_page)),

  body: PageView(

      children: <Widget>[

        DashboardScreen(),

        InstructionsScreen(),

        CatalogScreen(),

        ProfileScreen()

      ],

      controller: _pageController,

      onPageChanged: onPageChanged,

      physics: NeverScrollableScrollPhysics()),

  bottomNavigationBar: BottomNavigationBar(

    key: bottomNavigationBar,

    type: BottomNavigationBarType.shifting,

    onTap: navigationTapped,

    currentIndex: _page,

    items: [

      BottomNavigationBarItem(

          icon: Icon(Icons.home, color: Colors.grey),

          activeIcon:

              Icon(Icons.home, color: Theme.of(context).primaryColor),

          title: Text('Dashboard',

              style: TextStyle(color: Theme.of(context).primaryColor)),

          backgroundColor: Colors.white),

      BottomNavigationBarItem(

          icon: Icon(Icons.receipt, color: Colors.grey),

          activeIcon:

              Icon(Icons.receipt, color: Theme.of(context).primaryColor),

          title: Text('Instructions',

              style: TextStyle(color: Theme.of(context).primaryColor)),

          backgroundColor: Colors.white),

      BottomNavigationBarItem(

          icon: Icon(Icons.dashboard, color: Colors.grey),

          activeIcon:

              Icon(Icons.dashboard, color: Theme.of(context).primaryColor),

          title: Text('Catalog',

              style: TextStyle(color: Theme.of(context).primaryColor)),

          backgroundColor: Colors.white),

      BottomNavigationBarItem(

          icon: Icon(Icons.person, color: Colors.grey),

          activeIcon:

              Icon(Icons.person, color: Theme.of(context).primaryColor),

          title: Text('Profile',

              style: TextStyle(color: Theme.of(context).primaryColor)),

          backgroundColor: Colors.white)

    ],

  ),

);



void navigationTapped(int page) {

  _pageController.animateToPage(page,

    duration: const Duration(milliseconds: 300), curve: Curves.ease);

}



void onPageChanged(int page) {

  setState(() {

    this._page = page;

  });

}

In the DashboardScreen for example, I go to a new page like:

Navigator.of(context)

            .push(MaterialPageRoute(builder: (context) => CodeScreen()))

How can I fix this? I need to use Redux or Bloc to achieve this?

Thanks.
