MemoryImage class

Decodes the given Uint8List buffer as an image, associating it with the given scale.

The provided bytes buffer should not be changed after it is provided to a MemoryImage. To provide an ImageStream that represents an image that changes over time, consider creating a new subclass of ImageProvider whose load method returns a subclass of ImageStreamCompleter that can handle providing multiple images.
