旋转木马滑块项中的颤振动态列表

Question

我有一个来自服务器的动态列表图像，我想在Carousel滑块中推送它们。但是当我将它们添加到项目中并运行时，我得到了这个错误:

Class 'String' has no instance method 'map'.
Tried calling: map(Closure: (dynamic) => Builder)

，这是我的代码。

child: Container(
// width: pageWidth * 0.84,
height: pageWidth * 0.42,
child: CarouselSlider(
options: CarouselOptions(
height: pageWidth * 0.42,
aspectRatio: 1,
viewportFraction: 1,
autoPlay: true,
autoPlayInterval: const Duration(seconds:5),
enableInfiniteScroll: true,
enlargeCenterPage: true,

),
items : [
ListView.builder(itemBuilder: (context ,index){
return  homeView.details![index]['Image'];})].map((i){
return Builder(
builder:(BuildContext context) {
return    ListView.builder(
scrollDirection: Axis.horizontal,
itemCount: homeView.details!.length,
itemBuilder: (context, index) {
return Container(
width: pageWidth * 0.84,
height: pageWidth * 0.42,
// margin: EdgeInsets.only(left: 15),
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.cover,
image: NetworkImage(i),
),
borderRadius: BorderRadius.all(
Radius.circular(15),),));});});}).toList(),

Answer 1

使用CarouselSlider.builder()

CarouselSlider.builder (itemCount: 15日itemBuilder: (BuildContext context, int itemIndex, int pageViewIndex) =>容器(孩子:文本(itemIndex.toString ()),)，)
