transition between pages using indicators in the flutter

Question

I have 2 pages, on one of them I have placed the code which displays indexers, I want to swipe on indexes to pass between pages. I can't figure out how to set it up. I will be grateful for your help.

 Container(
               child: SmoothPageIndicator(
                 controller: _pageController,
                 count:  _pages.length,
                 effect: JumpingDotEffect(
                   dotHeight: 16,
                   dotWidth: 16,
                   jumpScale: .7,
                   verticalOffset: 15,
                ),
                   onDotClicked: _onchanged
              ),
            ),

List of pages:

  List<Widget> _pages = [
    Form_scan(),
    Form_ttn()
  ];

Image indecators

I will be grateful if someone helps me to go from the first page to the second (swipe right) with these indicators

Answer 1

use PageView, :

PageView(
        controller: _pageController,
        children: [
          Form_scan(),
          Form_ttn()
        ],
      ),

make a PageController :

final PageController _pageController = PageController();

onDotClicked: _onchanged

void _onchanged(){
_pageController.animateToPage(
          indexHalaman,
          duration: Duration(milliseconds: 500),
          curve: Curves.fastOutSlowIn
      );
}

indexHalaman = page index, if you have 2 widget on pageView children then first page index = 0, next index page = 1, if you use stateful widget, dont forget to use setState, or maybe you can use bloc pattern for this
