I hope that when using GFAlert and showDialog together, GFAlert can be vertically centered.

Is your feature request related to a problem? Please describe.

It seems that the native GFAlert needs to be used with GFFloatingWidget because it requires providing some containers, masks, etc. This is too complicated and inflexible for popping up dialogs on other pages. Therefore, I want to use showDialog with Material to simplify the use of GFAlert. However, I found that GFAlert cannot be vertically centered even if I set the alignment of GFAlert to center. I also tried wrapping GFAlert with a layer of GFFloatingWidget, but it still doesn't work. So, I came here to ask questions, haha.

Describe the solution you'd like

just like:

static void showCustomDialog(BuildContext context,
      {required Widget widget, bool refuseBack = true, String? title, VoidCallback? onOk}) {
    showDialog(
      context: context,
      barrierDismissible: false,
      barrierColor: Colors.black54,
      builder: (BuildContext context) {
        return WillPopScope(
          onWillPop: () async => !refuseBack,
          child: GFAlert(
            title: title,
            content: widget,
            alignment: Alignment.center,
            onTapOk: () {
              onOk?.call();
              Navigator.pop(context);
            },
            onTapCancel: () {
              Navigator.pop(context);
            },
          ),
        );
      },
    );
  }

Describe alternatives you've considered

static void showCustomDialog(BuildContext context,
      {required Widget widget, bool refuseBack = true, String? title, VoidCallback? onOk}) {
    showDialog(
      context: context,
      barrierDismissible: false,
      barrierColor: Colors.black54,
      builder: (BuildContext context) {
        return WillPopScope(
          onWillPop: () async => !refuseBack,
          child: GFFloatingWidget(
            body: GFAlert(
              title: title,
              content: widget,
              alignment: Alignment.center,
              onTapOk: () {
                onOk?.call();
                Navigator.pop(context);
              },
              onTapCancel: () {
                Navigator.pop(context);
              },
            ),
          ),
        );
      },
    );
  }
