Properties

assetName → String
The name of the asset.
finalinherited
bundle → AssetBundle?
The bundle from which the image will be obtained.
finalinherited
cacheRawData → bool
Whether cache raw data if you need to get raw data directly. For example, we need raw image data to edit, but ui.Image.toByteData() is very slow. So we cache the image data here.
final
hashCode → int
The hash code for this object.
no setterinherited
imageCache → ImageCache
The ImageCache which this is stored in it.
no setterinherited
imageCacheName → String?
The name of ImageCache, you can define custom ImageCache to store this provider.
final
keyName → String
The key to use to obtain the resource from the bundle. This is the argument passed to AssetBundle.load.
no setterinherited
package → String?
The name of the package from which the image is included. See the documentation for the ExactAssetImage class itself for details.
finalinherited
rawImageData → Uint8List
The raw data of image
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scale → double
The scale to place in the ImageInfo object of the image.

Methods

createStream(ImageConfiguration configuration) → ImageStream
Called by resolve to create the ImageStream it returns.
inherited
evict({ImageCache? cache, ImageConfiguration configuration = ImageConfiguration.empty, bool includeLive = true}) → Future<bool>
Evicts an entry from the image cache.
inherited
instantiateImageCodec(Uint8List data, ImageDecoderCallback decode) → Future<Codec>
Override this method, so that you can handle raw image data, for example, compress
inherited
loadBuffer(AssetBundleImageKey key, DecoderBufferCallback decode) → ImageStreamCompleter
Converts a key into an ImageStreamCompleter, and begins fetching the image.
inherited
loadImage(AssetBundleImageKey key, ImageDecoderCallback decode) → ImageStreamCompleter
Converts a key into an ImageStreamCompleter, and begins fetching the image.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
obtainCacheStatus({required ImageConfiguration configuration, ImageErrorListener? handleError}) → Future<ImageCacheStatus?>
Returns the cache location for the key that this ImageProvider creates.
inherited
obtainKey(ImageConfiguration configuration) → Future<ExtendedAssetBundleImageKey>
Converts an ImageProvider's settings plus an ImageConfiguration to a key that describes the precise image to load.
override
obtainNewKey<S>(S createNewKey(AssetBundleImageKey value), Future<AssetBundleImageKey> obtainKey()) → Future<S>
obtain new key base on old key
inherited
resolve(ImageConfiguration configuration) → ImageStream
Resolves this image provider using the given configuration, returning an ImageStream.
inherited
resolveStreamForKey(ImageConfiguration configuration, ImageStream stream, AssetBundleImageKey key, ImageErrorListener handleError) → void
Called by resolve with the key returned by obtainKey.
inherited
toString() → String
A string representation of this object.
