I hope this helps.

GestureDetector(
 onLongPressStart: (details) async{
  final offset = details.globalPosition;

  showMenu(
    context: context,
    position: RelativeRect.fromLTRB(
      offset.dx,
      offset.dy,
      MediaQuery.of(context).size.width - offset.dx,
      MediaQuery.of(context).size.height - offset.dy,
    ),
    items: [
      PopupMenuItem(
        child: Text("0"),
      ),

      PopupMenuItem(
        child: Text("1"),
      ),

      PopupMenuItem(
        child: Text("2"),
      ),

    ]
);

},
 child: FaIcon(
   AppIcons.ellipseFa,
   size: 22,
 ),
)
