how about null safety?

package:flutter/src/widgets/media_query.dart': Failed assertion: line 819 pos 12: 'context != null': is not true

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

i need text hidden in popup menu

If I change orientation from portrait to landscape or vice versa, pop up menu remains opened. It should be closed.

例如边框颜色、边框厚度、阴影设置

Any idea how to solve this?

Thanks.

很好用，可否增加圆角半径配置，默认的10有点大

Hey, is there anyway of adding custom widgets instead of multiple menu items

Please, migrate this package to null safety.

Regarding the itemWidth in MenuConfig, this setting will not be synchronized to the grid type itemWidth after external modifications, as the itemWidth in MenuConfig was not passed to the GridLayout. Modifying the itemWidth will affect the overall width, but it will not change the width of each item because you have written the item width to 72

页面返回之后,菜单没有销毁

Please Help Me On this... I'm getting this error After upgrading Flutter Sdk

How can I get the index of a selected menu item?

The method 'findRenderObject' was called on null.
Receiver: null
Tried calling: findRenderObject()

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.

单个的item的UI是否可以自定义.配置宽高,圆角,弧度大小等

We need this to support null safety please

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

Is it possible to insert a SizedBox (height: value), between the image and the displayed text?

I need to change the height through the parent component, but now the change cannot be changed, it is too high!

建议pop框的menuWidth宽，menuHeight高都写成开放的属性，在外部可以直接修改宽高属性。

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

On click of a menu item, i need to send data which need to be processed or which need to be sent to a new page on click, which is not possible

Hi

I am trying this lib and is great, but the field maxcolumn seems dont work properly

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,
          );
        },
      )

flutter: menu is showing

fixed：

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,),
                ),
              );
    }

  }

onClickMenu
长按释放不触发事件

呼出菜单会出现在页面左上角而不是在点击的widget上，context和key都使用了。
