manage the position of showMenu in flutter

Question

I have a GestureDetector and at the onPressed I have a showMenu, but I can't make the menu close to the button that I've created.

Here is my code: note that I've already used RelativeRect.fill for the position just to run the app.

ElevatedButton(
                style: ElevatedButton.styleFrom(
                  primary: ColorConstants.kContainerColor,
                  shape:  RoundedRectangleBorder(
                    borderRadius: BorderRadius.circular(10),
                  ),
                ),
                onPressed: (){
                  showMenu(context: context, position: RelativeRect.fill, items: [
                    PopupMenuItem(child: Text('hello')),
                    PopupMenuItem(child: Text('hello')),
                    PopupMenuItem(child: Text('hello')),
                    PopupMenuItem(child: Text('hello')),
                  ]);
                }, child: Padding(
                  padding: const EdgeInsets.all(12),
                  child: SvgPicture.asset('images/menubar.svg',
                  color: Colors.white,
                  height: 27,
                  width: 27,)
                )),

This answer from Ayman can help you!

He used PopupMenuButton instead of showMenu

PopupMenuButton<int>(
    offset: const Offset(0, -380),
    itemBuilder: (context) => [
      PopupMenuItem<int>(
          value: 0,
          child: PopUpMenuTile(
            isActive: true,
            icon: Icons.fiber_manual_record,
            title:'Stop recording',
          )),
      PopupMenuItem<int>(
          value: 1,
          child: PopUpMenuTile(
            isActive: true,
            icon: Icons.pause,
            title: 'Pause recording',
          )),
      PopupMenuItem<int>(
          value: 2,
          child: PopUpMenuTile(
            icon: Icons.group,
            title: 'Members',
          )),
      PopupMenuItem<int>(
          value: 3,
          child: PopUpMenuTile(
            icon: Icons.person_add,
            title: 'Invite members',
          )),
    ],
    child: Column(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
        Icon(Icons.more_vert,
            color: Colors.white60),
        Text(translate('more'),
            style: Theme.of(context)
                .textTheme
                .caption)
      ],
    ),
  )
