cached_network_image 2.0.0

Flutter library to load and cache network images. Can also be used with placeholder and error widgets.

Cached network image

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) => CircularProgressIndicator(),
        errorWidget: (context, url, error) => Icon(Icons.error),
     ),

Image(image: CachedNetworkImageProvider(url))

When you want to have both the placeholder 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.
