I have an application that pulls data from Json Dan. I want to pull the data and show it in the carousel. There is no error on the screen and vscode. But my pictures are not visible in the carousel and I get an error like this.
SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.min,
children: [
SizedBox(
height: 300.0,
width: double.infinity,
child: ListView.builder(
itemCount: snapshot.data.pictures.length - 1,
itemBuilder: (context, index) {
return Carousel(
dotSize: 5,
dotIncreaseSize: 5,
images: [
Image.network(snapshot
.data.pictures[index].pictureurl)
],
);
},
),
),...
])
