Cached network image #

A flutter library to show images from the internet and keep them in the cache directory.

How to use #

The CachedNetworkImage can be used directly or through the ImageProvider.

new CachedNetworkImage(
       imageUrl: "http://via.placeholder.com/350x150",
       placeholder: new CircularProgressIndicator(),
       errorWidget: new Icon(Icons.error),
     ),

new Image(image: new CachedNetworkImageProvider(url))

How it works #

The cached network images stores and retrieves files using the flutter_cache_manager.
