ImageInfo class Null safety

A dart:ui.Image object with its corresponding scale.

ImageInfo objects are used by ImageStream objects to represent the actual data of the image once it has been obtained.

The receiver of an ImageInfo object must call dispose. To safely share the object with other clients, use the clone method before calling dispose.
