loadBuffer abstract method

  1. @override
ImageStreamCompleter loadBuffer(
  1. NetworkImage key,
  2. DecoderBufferCallback decode

Converts a key into an ImageStreamCompleter, and begins fetching the image.

For backwards-compatibility the default implementation of this method returns an object that will cause resolveStreamForKey to consult load. However, implementors of this interface should only override this method and not load, which is deprecated.

The decode callback provides the logic to obtain the codec for the image.

  • ResizeImage, for modifying the key to account for cache dimensions.
