//When items are updated in a LazyGroupGallery, only it rebuilds with the
//new state of _files which is a state variable in it's state object.
//widget.files does not change as the Widget itself is immutable. So
//to create a new Widget of LazyLoadingGallery with the updated
//widget.files, we have to call setState from an ancestor state object.
//widget.files is not updated. Calling setState from it's ancestor
//state object 'Gallery' creates a new LazyLoadingGallery widget with
//updated widget.files
//If widget.files is kept in it's old state, the old state will come
//up when scrolled down and back up to the group.
//[galleryState] will never be null except when LazyLoadingGallery is
//used without Gallery as an ancestor.
