Example 3: flutter cached network image not working

Worked for me after searching all over the sites :=>

1. Install the latest dependency for cached_network_image:
2. Stop and Restart the app if you are debugging or running

If not goahead with other steps:

3. Flutter clean
4. Quite from IDE
5. Reopen your IDE and run pub get

Example:

CachedNetworkImage(
   imageUrl: 'https://picsum.photos/250?image=9',
   fit: BoxFit.cover,
   width: MediaQuery.of(context).size.width,
   placeholder: (context,url) => CircularProgressIndicator(),
   errorWidget: (context,url,error) => new Icon(Icons.error),
 )
 
###### OR ######

Image(image: CachedNetworkImageProvider('https://picsum.photos/250?image=9'))
