I was able to work out the problem with the widget. The call to widget.onTap is incorrect. It should be widget.onTap?.call();

if (widget.onTap != null) { /// Developers who uses this package can add custom functionality when tapped. /// /// When a developer defines an extra option on tap, this will be executed. If not provided this step will be skipped. /// ignore: unnecessary_statements widget.onTap?.call(); }
