Reading Notes About Image Widget
The PDF as follows illustrates the mechanics of Image Widget, which is widely used in project to present photos. The Image Widget
implements cache pool, which means it presents the resource in the cache pool if present, otherwise, it tries to load the image info.
The loading of image is a completer that will emit the updating image info and ‘set state’ while it is complete, in this way, the widget
shows the final image.
