I am having an issue while changing the value in the alert dialog box in flutter. I want to change value of it without closing alert box

CodePudding user response：

you can use like this

 dialoge(BuildContext context) {
    showDialog(
        context: context,
        builder: (context) {
          return AlertDialog(
            scrollable: true,
            contentPadding: EdgeInsets.all(5),
            title: Center(
                child: Text(
              'Product Detail',
              style: TextStyle(
                color: yellowColor,
              ),
            )),
            content: shownecklace(selectedpp: selectedpp),
          );
        });
  }

Make alert dialogue uge box within a stateful widget

class shownecklace extends StatefulWidget {
  int selectedpp;
  shownecklace({Key? key, required this.selectedpp}) : super(key: key);

  @override
  _shownecklaceState createState() => _shownecklaceState();
}

class _shownecklaceState extends State<shownecklace> {
  @override
  Widget build(BuildContext context) {
    return Container(
      width: 675,
      height: 475,
      child: Column(
        children: [
          Padding(
            padding: const EdgeInsets.only(top: 5.0),
            child: Container(
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(5),
                color: blackColor,
              ),
              height: 460,
              child: PageView.builder(
                itemCount: ProductDetailsModel.productDetailsList.length,
                controller: PageController(initialPage: widget.selectedpp, keepPage: true, viewportFraction: 1),
                itemBuilder: (BuildContext context, int index) {
                  return Column(
                    crossAxisAlignment: CrossAxisAlignment.start,

                        width: double.infinity,
                        child: PinchZoom(
