Need to add dependency package

flukit: ^1.0.0
 Quote  import 'package:flukit/flukit.dart';
// This 1 Put it where you want to display the carousel 
AspectRatio(
  aspectRatio:1.0,// 16.0 / 9.0,
  child: Swiper(
   indicatorAlignment: AlignmentDirectional.topEnd,
   circular: true,
   autoStart:false,
   indicator: NumberSwiperIndicator(),// Used by the official   Fractional subscript 
   children:AspecRaticImgs(pro.image),// This is 1 A List<String> Parameters of type, stored pictures Url List 
  ),
  );

// Carousel picture 
class NumberSwiperIndicator extends SwiperIndicator{
 @override
 Widget build(BuildContext context, int index, int itemCount) {
 if(itemCount>1){
 return Container(
  decoration: BoxDecoration(
   color: Colors.black45,
   borderRadius: BorderRadius.circular(20.0)
  ),
  margin: EdgeInsets.only(top: 10.0,right: 5.0),

  child: Text("${++index}/$itemCount", style: TextStyle(color: SQColor.white, fontSize: 18.0)),

 }else{
  return Container();
 }
 }
}

// Here I 1 Start using foreach Loop, find no way   Will report an error and say I add Empty objects, headaches, and C# It's really quite different 
List<Widget> AspecRaticImgs(List<String> imgUrl) {
 return imgUrl.map<Widget>((url){
 return Image.network(
  url,
  height: 400,
  fit: BoxFit.cover,
 );
 }).toList();
}

List<Widget> AspecRaticImgs(List<String> imgUrl) {
 return imgUrl.map<Widget>((url){
 return CachedNetworkImage(// This load is more comfortable, and when it is in load, there are 1 Load progress 
  imageUrl: url,
