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.
const
Properties

A representation of the runtime type of the object.

other) → bool -
The equality operator.

Methods
-
decodeImage(
ByteData data) → Future<Image> -
Converts raw image data from a ByteData buffer into a decoded ui.Image which can be passed to a
Canvas. -
load(
AssetBundleImageKey key) → ImageStreamCompleter -
Converts a key into an ImageStreamCompleter, and begins fetching the image using loadAsync.
-
loadAsync(
AssetBundleImageKey key) → Future<ImageInfo> -
Fetches the image from the asset bundle, decodes it, and returns a corresponding ImageInfo object.
-
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.
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.
