  late final String foldername;
   late final int categorynumber;
  late final int index;
  late final String categoryname;

  Singleimage(this.foldername, this.categorynumber, this.index, this.categoryname);

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

class _SingleimageState extends State<singleimage> {
  PageController controller = PageController();

  Duration pageTurnDuration = Duration(milliseconds: 500);
  Curve pageTurnCurve = Curves.ease;
  @override
  void initState() {
    super.initState();

  }



    @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title:Text('Name'),
      ),
      body: PageView.builder(
        onPageChanged: (int page) {
          // this page variable is the new page and will change before the pageController fully reaches the full, rounded int value
    
        },

        itemBuilder: (context, position) {
          return Container(
            child: Text('${position}',style: TextStyle(
              fontSize: 20
            ),),
