<itemvalue="A builder function responsible for creating the widget that represents this image. If this is null, this widget will display an image that is painted as soon as the first image frame is available (and will appear to "pop" in if it becomes available asynchronously). Callers might use this builder to add effects to the image (such as fading the image in when it becomes available) or to display a placeholder widget while the image is loading."/>

<itemvalue="Whether this widget should prevent other [MouseRegion]s visually behind it from detecting the pointer. This changes the list of regions that a pointer hovers, thus affecting how their [onHover], [onEnter], [onExit], and [cursor] behave. If [opaque] is true, this widget will absorb the mouse pointer and prevent this widget's siblings (or any other widgets that are not ancestors or descendants of this widget) from detecting the mouse pointer even when the pointer is within their areas. If [opaque] is false, this object will not affect how [MouseRegion]s behind it behave, which will detect the mouse pointer as long as the pointer is within their areas. This defaults to true."/>

<itemvalue="A widget that lays the child out as if it was in the tree, but without painting anything, without making the child available for hit testing, and without taking any room in the parent. Offstage children are still active: they can receive focus and have keyboard input directed to them."/>
<itemvalue="Cancels this subscription. After this call, the subscription no longer receives events. 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."/>
