[Bug]: 从iOS原生端模态弹出Flutter页面，Flutter页面设置透明，结果Flutter页面呈现白色全屏

[applebest]

请描述遇到的问题，以及您所期望的正确的结果

iOS原生端：

       let vc:FBFlutterViewContainer = FlutterVC()
        vc.setName(options.pageName, uniqueId: options.uniqueId, params: options.arguments,opaque: options.opaque)
        vc.view.backgroundColor = .clear
        self.present(vc, animated: true, completion: nil)

Flutter端路由代理：

   RouterPath.memberAlert: (settings, uniqueId) {
 

      return ModalBottomSheetRoute(
        settings: settings,
        enableDrag: true,
        isDismissible: true,
        backgroundColor: Colors.transparent,
        modalBarrierColor: Colors.transparent,
        builder: (context) {
          // return const MemberAlert();

          return AnimatedPadding(
              padding: MediaQuery.of(context).viewInsets,
              // padding: EdgeInsets.zero,
              duration: const Duration(milliseconds: 100),
              curve: Curves.decelerate,
              child: const MemberAlert());
        },
        isScrollControlled: false,
      );
    }

Widget

const MemberAlert({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.transparent,
      body: Align(
        alignment: Alignment.bottomCenter,
        child: ClickWidget(
          onTap: () => Nav.unfocus(),
          child: ClipRRect(
            borderRadius: BorderRadius.only(
                topLeft: Radius.circular(12.r),
                topRight: Radius.circular(12.r)),
            child: Container(

xCode , Debug View Hierarchy打印

发现FlutterView背景是UIExtendedGrayColorSpace

希望能在现有的页面之上，弹出一个透明的提示框
