NetworkImageWithRetry class

Fetches the image from the given URL, associating it with the given scale.

If fetchStrategy is specified, uses it instead of the defaultFetchStrategy to obtain instructions for fetching the URL.

The image will be cached regardless of cache headers from the server.

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
load(NetworkImageWithRetry key, dynamic decode) → ImageStreamCompleter
loadBuffer(NetworkImageWithRetry key, DecoderBufferCallback decode) → ImageStreamCompleter

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<NetworkImageWithRetry>
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, NetworkImageWithRetry key, ImageErrorListener handleError) → void
Called by resolve with the key returned by obtainKey.
inherited
toString() → String
A string representation of this object.
