AssetBundleImageProvider class

A subclass of ImageProvider that knows about AssetBundles.

This factors out the common logic of AssetBundle-based ImageProvider classes, simplifying what subclasses must implement to just obtainKey.

Returns the cache location for the key that this ImageProvider creates. [...]
inherited
obtainKey(ImageConfiguration configuration) Future<AssetBundleImageKey>
Converts an ImageProvider's settings plus an ImageConfiguration to a key that describes the precise image to load. [...]
inherited
resolve(ImageConfiguration configuration) ImageStream
Resolves this image provider using the given configuration, returning an ImageStream. [...]
@nonVirtual, inherited
resolveStreamForKey(ImageConfiguration configuration, ImageStream stream, AssetBundleImageKey key, ImageErrorListener handleError) → void
