    Future.delayed(Duration(milliseconds: 0)).then((f) {
      setState(() {
        rightPaddingValue = 10;
      });
    });
    super.initState();
    images.add(mainImage);
    images.add(contentImage1);
    images.add(contentImage2);
    images.add(contentImage3);
    images.add(contentImage4);
  }



@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: CustomScrollView(
        slivers: <Widget>[
          SliverAppBar(
            backgroundColor: Colors.white70,
            expandedHeight: 270,
            flexibleSpace: FlexibleSpaceBar(
              background: Hero(
                tag: tag,
                child: CarouselSlider(
                  height: 400.0,                  
                  autoPlay: true,
                  enlargeCenterPage: true,
                  items: images.map((i) {
                    return Builder(
                      builder: (BuildContext context) {
                        return Container(
                          width: MediaQuery.of(context).size.width,
                          child: Image(
                            image: CachedNetworkImageProvider(i),
                            fit: BoxFit.cover,
