How can I add this custom widget ?

hey guys I'm facing some problems adding this custom widget to my project
I'm using the photo_gallery package but the parameter Album isn't supported within Flutterflow
is there any workaround for this issue?
Custom widget GridItem cannot be parsed.
Unable to process Parameter album

  final double? width;
  final double? height;
  final Album album;

  @override

class _GridItemState extends State<GridItem> {

// Set your widget name, define your parameter, and then add the
