how do i move from the first page, to another page by using items from the first page

CodePudding user response：

So basically you can create a variable that contains the value on your first page and while you add your pages in any list you can simply pass that value like

int test=0
  final List<Widget> _list = [];
  @override
  void initState() {
    super.initState();
    _list.addAll(
        const [DashboardScreen(test), WishListScreen(),   CartScreen(), ProfileScreen()]);
  }

And other side in dashboardscreen

  final int test;
  const DashboardScreen(this.test, {Key? key}) : super(key: key);

if your page is statful widget then in build file you can simple use widget.test or if you have stateless widget you can directly use test variable

You can use page controller

// through the page controller you can do using animateToPage or _pageController.jumpToPage(0). here 0 is page index
