<itemvalue="The `wasSynchronouslyLoaded` argument specifies whether the image was available synchronously (on the same [rendering pipeline frame](renderingRendererBindingdrawFrame.html) as the `Image` widget itself was created) and thus able to be painted immediately. If this is false, then there was one or more rendering pipeline frames where the image wasn't yet available to be painted. For multi-frame images (such as animated GIFs), the value of this argument will be the same for all image frames. In other words, if the first image frame was available immediately, then this argument will be true for all image frames."/>
<itemvalue="The `child` argument contains the default image widget and is guaranteed to be non-null. Typically, this builder will wrap the `child` widget in some way and return the wrapped widget. If this builder returns `child` directly, it will yield the same result as if [Image.frameBuilder] was null. The `frame` argument specifies the index of the current image frame being rendered. It will be null before the first image frame is ready, and zero for the first image frame. For single-frame images, it will never be greater than zero. For multi-frame images (such as animated GIFs), it will increase by one every time a new image frame is shown (including when the image animates in a loop)."/>

The stream may need to shut down the source of events and clean up after the subscription is canceled. Returns a future that is completed once the stream has finished its cleanup. Typically, cleanup happens when the stream needs to release resources. For example, a stream might need to close an open file (as an asynchronous operation). If the listener wants to delete the file after having canceled the subscription, it must wait for the cleanup future to complete. If the cleanup throws, which it really shouldn't, the returned future completes with that error."/>
