How to force jumptotab in each build of PersistentTabView?

[vontdeux]

I have the PersistentTabView setup in provider condition, eg:

Widget build(BuildContext context) => Consumer<ProviderSample>(
        builder: (_, condition, __) {
            _controller!.jumpToTab(1);  // adding this wont make the tab to force to jump tab
            _controller!.index = 1; //neither did this.
            
            return PersistentTabView(
                controller: _controller,
                screens: (condition) ? _buildScreens()  : _buildScreens2(), 
                items: (condition) ? _navBarsItems()  : _navBarsItems2(),
                ....
                });

Screens buildScreen() - has 5 screens buildScreen2() - has 2 screens

Items _navBarsItems() - has 5 items _navBarsItems2() - has 2 items

when the user is in condition true, _navBarsItems has 5, and if he is in 4th index of screen, the build seems to ignore _controller!.index = 1; and try to access _controller!.index = 3 (4th screen) anyway and error out of range is thrown.
