Cached network image

BREAKING CHANGES IN 0.6.0

Widget now uses builders for the placeholder and error widget and uses sqflite for cache management. See the docs for more information.

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.

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

Image(image: new CachedNetworkImageProvider(url))

When you want to have both the placholder functionality and want to get the imageprovider to use in another widget you can provide an imageBuilder:

CachedNetworkImage(
  imageUrl: "http://via.placeholder.com/200x150",
  imageBuilder: (context, imageProvider) => Container(
    decoration: BoxDecoration(
      image: DecorationImage(
          image: imageProvider,
          fit: BoxFit.cover,
          colorFilter:
              ColorFilter.mode(Colors.red, BlendMode.colorBurn)),
    ),
  ),
  placeholder: (context, url) => CircularProgressIndicator(),
  errorWidget: (context, url, error) => Icon(Icons.error),
),

How it works

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