asset_cache 0.3.0

Load and cache any local asset type given a decoder, with singletons for loading images, json and more.

asset_cache

asset_cache will load and cache any asset of type T given a decoder.

Since CachingAssetBundle does not cache binary data, we load and cache data ourselves.

Binary resources (from load) are not cached.

Create a custom asset cache by inheriting from AssetCache and pass it a decoder or inherit from GenericCache and override loadAsset.

We include the following AssetCache implementations:

• ImageAssetCache
• JsonAssetCache
• StringAssetCache
• ByteDataAssetCache

Usage

Add asset_cache to your pubspec.yaml:

dependencies:
  asset_cache:

Describe assets in your pubspec.yaml:

  assets:
     - assets/images/
     - assets/json/

Set AssetCache.basePath to avoid using full asset paths:

final imageCache = ImageAssetCache(basePath: "assets/images/");
final jsonCache = JsonAssetCache(basePath: "assets/json/");

Load and cache assets using load, which returns a Future<T>:

final image = await imageCache.load('sprite.png')
final json = await jsonCache.load('sprite.json')

See example and test

Based on CachingAssetBundle.
