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.

Constructors
- AssetBundleImageProvider()
-
Abstract const constructor. This constructor enables subclasses to provide
const constructors so that they can be used in const expressions.

Methods
-
load(
AssetBundleImageKey key) → ImageStreamCompleter -
Converts a key into an ImageStreamCompleter, and begins fetching the
image using
loadAsync.override -
evict(
{ImageCache cache, ImageConfiguration configuration: ImageConfiguration.empty }) → Future< bool> -
Evicts an entry from the image cache. [...]
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
obtainKey(
ImageConfiguration configuration) → Future< AssetBundleImageKey> -
Converts an ImageProvider's settings plus an ImageConfiguration to a key
that describes the precise image to load. [...]
@protected, inherited
-
resolve(
ImageConfiguration configuration) → ImageStream -
Resolves this image provider using the given
configuration, returning an ImageStream. [...]inherited -
toString(
) → String -
Returns a string representation of this object.
