ImageStreamCompleterHandle class
An opaque handle that keeps an ImageStreamCompleter alive even if it has lost its last listener.
To create a handle, use ImageStreamCompleter.keepAlive.
Such handles are useful when an image cache needs to keep a completer alive but does not actually have a listener subscribed, or when a widget that displays an image needs to temporarily unsubscribe from the completer but may re-subscribe in the future, for example when the TickerMode changes.
