How to control CupertinoContextMenu dividers thickness

Question

I want to control the thickness of CupertinoContextMenu's divider's, I didn't see this property in Theme class and also I was not able to spot customization on widgets properties, how would that be possible?

My code :

return CupertinoContextMenu.builder(
  builder: (context, animation) {
    return SizedBox(
      width: MediaQuery.of(context).size.width /
          (mainAxisCount - animation.value),
      height: MediaQuery.of(context).size.width /
          (mainAxisCount - animation.value),
      child: cardBox(context,
          ratioFactor: animation.value < sizeLimit
              ? null
              : (size * animation.value),
          shatter: shatter,
          actions: actions,
          animated: animation.value != 0.0),
    );
  },
  actions: contextMenuActions,
);

Current result:

It's expected to be able to change the thickness a little bit.

You cannot directly change the divider's thickness. But there is a work around Refering :https://github.com/flutter/flutter/blob/54e66469a9/packages/flutter/lib/src/cupertino/context_menu.dart#L155

You can recreate this into a context_menu_extended.dart and simply in the _ContextMenuSheet widget.

Change the width of Decorated Box as bellow.

DecoratedBox(
                  decoration: BoxDecoration(
                    border: Border(
                      top: BorderSide(
                        color: CupertinoDynamicColor.resolve(
                          _borderColor,
                          context,
                        ),
                        width: 0.4, // Change the width here.
                      ),
                    ),
                  ),
                  position: DecorationPosition.foreground,
                  child: action,
                ),
