flutterdartdatatablescrollbar

Flutter Scrollbar in vertical and horizontal axis

I have two scrollbars in my flutter project for scrolling the data table. Here are the codes.

  Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
            child: Container(
                width: MediaQuery.of(context).size.width * (1 / 2),
                height: MediaQuery.of(context).size.height * (1 / 2),
                child: Scrollbar(
                    isAlwaysShown: true,
                    controller: _controllerOne,
                    child: SingleChildScrollView(
                        scrollDirection: Axis.vertical,
                        controller: _controllerOne,
                        child: Scrollbar(
                          controller: _controllerTwo,
                          isAlwaysShown: true,
                          child: SingleChildScrollView(
                            scrollDirection: Axis.horizontal,
                            controller: _controllerTwo,
                            child: DataTable(
                             ...
                            ),
                          ),
                        ))))));
  }

These two scrollbars are working correctly. But I can not see both of them at the same time. I mean if I write the Scrollbar with scrollDirection in vertical first it's like;

Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
            child: Container(
                width: MediaQuery.of(context).size.width * (1 / 2),
                height: MediaQuery.of(context).size.height * (1 / 2),
                child: Scrollbar(
                    isAlwaysShown: true,
                    controller: _controllerOne,
                    child: SingleChildScrollView(
                        **scrollDirection: Axis.vertical,**
                        controller: _controllerOne,
                        child: Scrollbar(
                          controller: _controllerTwo,
                          isAlwaysShown: true,
                          child: SingleChildScrollView(
                            **scrollDirection: Axis.horizontal,**
                            controller: _controllerTwo,
                            child: DataTable(
                             ...
                            ),
                          ),
                        ))))));
  }

if I write the Scrollbar with scrollDirection in horizontal first it's like;

enter image description here

Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
            child: Container(
                width: MediaQuery.of(context).size.width * (1 / 2),
                height: MediaQuery.of(context).size.height * (1 / 2),
                child: Scrollbar(
                    isAlwaysShown: true,
                    controller: _controllerOne,
                    child: SingleChildScrollView(
                        **scrollDirection: Axis.horizontal,**
                        controller: _controllerOne,
                        child: Scrollbar(
                          controller: _controllerTwo,
                          isAlwaysShown: true,
                          child: SingleChildScrollView(
                            **scrollDirection: Axis.vertical,**
                            controller: _controllerTwo,
                            child: DataTable(
                             ...
                            ),
                          ),
                        ))))));
  }

When I scroll till the end I can see the other scrollbar for both directions. But when the table is shown I need to see them both at the same time.

Is there any solution for this?
