ExtendedAssetImageProvider class Null safety

Mixed in types


ExtendedAssetImageProvider(String assetName, {AssetBundle? bundle, String? package, bool cacheRawData = false, String? imageCacheName})


assetName String
The name of the main asset from the set of images to choose from. See the documentation for the AssetImage class itself for details.
final, inherited
bundle AssetBundle?
The bundle from which the image will be obtained. [...]
final, inherited
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.
hashCode int
The hash code for this object. [...]
read-only, inherited
imageCache ImageCache
The ImageCache which this is stored in it.
read-only, inherited
imageCacheName String?
The name of ImageCache, you can define custom ImageCache to store this provider.
keyName String
The name used to generate the key to obtain the asset. For local assets this is assetName, and for assets from packages the assetName is prefixed 'packages/
read-only, inherited
package String?
The name of the package from which the image is included. See the documentation for the AssetImage class itself for details.
final, inherited
rawImageData Uint8List
The raw data of image
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.

createStream(ImageConfiguration configuration) ImageStream
Called by resolve to create the ImageStream it returns. [...]
@protected, inherited
evict({ImageCache? cache, ImageConfiguration configuration = ImageConfiguration.empty, bool includeLive = true}) Future<bool>
Evicts an entry from the image cache.
instantiateImageCodec(Uint8List data, DecoderCallback decode) Future<Codec>
Override this method, so that you can handle raw image data, for example, compress
load(AssetBundleImageKey key, DecoderCallback decode) ImageStreamCompleter
Converts a key into an ImageStreamCompleter, and begins fetching the image.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
obtainCacheStatus({required ImageConfiguration configuration, ImageErrorListener? handleError}) Future<ImageCacheStatus?>
Returns the cache location for the key that this ImageProvider creates. [...]
obtainKey(ImageConfiguration configuration) Future<ExtendedAssetBundleImageKey>
Converts an ImageProvider's settings plus an ImageConfiguration to a key that describes the precise image to load. [...]
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
Called by resolve with the key returned by obtainKey. [...]
toString() String
A string representation of this object. [...]


operator ==(Object other) bool
The equality operator. [...]
