GalleryOverlay class
If the user passes a overlayController to the gallery, this is used to display the overlay widget. The overlay is updated through a StreamBuilder and can fade in and out when the gallery is tapped. initialData is required when an overlay needs to be displayed as soon as the gallery is opened as this is how StreamBuilder.initialData works.
