flutter loading images over network
// 1st approach: Circular Progress Indicator with actual bytes loaded
Image.network(imgURL,fit: BoxFit.fill,
loadingBuilder:(BuildContext context, Widget child,ImageChunkEvent loadingProgress) {
if (loadingProgress == null) return child;
return Center(
child: CircularProgressIndicator(
value: loadingProgress.expectedTotalBytes != null ?
loadingProgress.cumulativeBytesLoaded / loadingProgress.expectedTotalBytes
: null,
),
);
},
),
// 2nd approach: Package: cached_network_image:
CachedNetworkImage(
imageUrl: "http://via.placeholder.com/350x150",
placeholder: (context, url) => new CircularProgressIndicator(),
errorWidget: (context, url, error) => new Icon(Icons.error),
),
// 3rd approach: FadeInImage
FadeInImage.assetNetwork(
placeholder: 'assets/loading.gif',
image: 'https://picsum.photos/250?image=9',
),
