Can you show me your implementation?

class _MainTabScreenState extends State<MainTabScreen> {

  int _currentIndex = 0;
  PageController _pageController;

  @override
  void initState() {
    super.initState();
    _pageController = PageController();
  }

  @override
  void dispose() {
    _pageController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SizedBox.expand(
        child: PageView(
          controller: _pageController,
          onPageChanged: (index) {
            setState(() => _currentIndex = index);
          },
          children: <Widget>[
            Profile(),
            SwipeFeedPage(),
            ChatList(),
          ],
        ),
      ),
      bottomNavigationBar: BottomNavyBar(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        backgroundColor: Colors.white,
        selectedIndex: _currentIndex,
        onItemSelected: (index) {
          setState(() => _currentIndex = index);
          _pageController.jumpToPage(index);
        },
        items: <BottomNavyBarItem>[
          BottomNavyBarItem(
            title: Text('Profile'),
            icon: Icon(Icons.supervised_user_circle),
            activeColor: Colors.red,
            textAlign: TextAlign.center,
          ),
          BottomNavyBarItem(
            title: Text('MatchBox'),
            icon: Icon(Icons.apps),
            textAlign: TextAlign.center,
          ),
          BottomNavyBarItem(
            title: Text('Message'),
            icon: Icon(Icons.chat_bubble),
            textAlign: TextAlign.center,
          ),
        ],
      ),
    );
  }
}

what do you think?

[pedromassango]

Sorry I tested your code but didn't come to give you a feedback. Your code is working fine here. Have you any other piece of code that can cause this behaviour?

what do you think?

it's lag also to me but only when the widget that is going to open is to complex, heavy

[pedromassango]

What type of heavy complexity/operations are you doing there?

Maybe the problem is not related to this package

I don't think it's related to your library. It lags to me when it's going to open a widget with a lot of lines (complex, many other widgetsh inside). With light layouts it's not lagging

Hey guys try running your apps in profile mode using --profile argument! That's not laggy that much in release mode or profile mode!!!

Good. So I will close this for now, But the chat can continue here...
