Methods

createStream(ImageConfiguration configuration) → ImageStream
Called by resolve to create the ImageStream it returns.
inherited
evict({ImageCache? cache, ImageConfiguration configuration = ImageConfiguration.empty}) → Future<bool>
Evicts an entry from the image cache.
inherited
getNativeImage<T>(String imageName, String suffix, bool isByte) → Future<T?>?
load(NativeImageProvider key, dynamic decode) → ImageStreamCompleter
loadBuffer(NativeImageProvider key, DecoderBufferCallback decode) → ImageStreamCompleter

inherited
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<NativeImageProvider>
Converts an ImageProvider's settings plus an ImageConfiguration to a key that describes the precise image to load.
override
resolve(ImageConfiguration configuration) → ImageStream
Resolves this image provider using the given configuration, returning an ImageStream.
inherited
resolveStreamForKey(ImageConfiguration configuration, ImageStream stream, NativeImageProvider key, ImageErrorListener handleError) → void
