Hi, really love your package but there's no available method or functionality to listen to the open and close state of the popup menu in order to dynamically open or close the menu when required? Thanks

fixed：

Offset _calculateOffset(BuildContext context) { double dx = _showRect.left + _showRect.width / 2.0 - menuWidth() / 2.0; if (dx < 10.0) { dx = 10.0; }

double dy = _showRect.top - menuHeight();
if (dy <= MediaQuery.of(context).padding.top + 10) {
  // The have not enough space above, show menu under the widget.
  dy = arrowHeight + _showRect.height + _showRect.top;
  _isDown = false;
} else {
  /// #######需要加上这行代码，修复三角形的高度
  dy -= arrowHeight; 
  _isDown = true;
}

return Offset(dx, dy);

}

The MenuItem has the userInfo property

MenuItem({this.title, this.image, this.userInfo, this.textStyle});

However this is missing in the OnClick.. MenuItemProvider

  void onPopMenuClick(MenuItemProvider item) {

    if (item.userIfno == "Note"){ \\ <<<<<<< MISSING......
      Navigator.push(
                context,
                MaterialPageRoute(
                  builder: (context) => NoteScreen(job_id: this.job.job_id, sys_track_id: 0,),
                ),
              );
    }

  }

This error occur when try to showPopup with ListView.builder

  ListView.builder(
        itemCount: list.length,
        itemBuilder: (context, index) {
         return MaterialButton(
            key:  btnKey,
            child: ListTile(
              title: Text("Title"),
              subtitle: Text("Title"),
              onTap: showPopup,
            ),
            onPressed: showPopup,
          );
        },
      )

Thanks a whole lot for your quick responses and dedication to this project. I would suggest an improvement of closing the popup menu if other gestures like swipe/scroll (on page) occurs. This is because the menu only closes if a user taps on the menu item or outside the menu but not other gestures (like scroll through a list the menu still remains open). Thanks

Hi, I'm creating a menu as follows:

                        PopupMenu menu = PopupMenu(
                            maxColumn: 6,
                            lineColor: Colors.grey,
                            items: repository.getAllUsers().map((e) => MenuItem(
                                title: repository.getUserNameForId(e.id),
                            )).toList(),
                            onClickMenu: (item) {

                            }
                        );
                        menu.show(widgetKey: key);

But the last line is not drawn. Please see attached:

This error occurs when creating all number of column number

Please advise

The 'menu content' is a Positioned component, and it center.x was equals parent widget's center.x, so when parent's postion is closer to screen's right side, set Positioned's left = offset.dx will cause a part of menu content is hidden. I already change code to left = 10 on my project and feel better.
