flutter web 中未显示滚动条。我的第二次尝试是：

Widget getSecondStep() {
        return  DraggableScrollbar.arrows(
          controller: ScrollController(),
          child: ListView(
              shrinkWrap: true,
              children: <Widget>[
                Row(
                  mainAxisSize: MainAxisSize.min,
                  mainAxisAlignment: MainAxisAlignment.center,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: <Widget>[BlaBlaBla(), BlaBla()],
                ),
              ],
            ),
        );
      }

我的第一次尝试是：

Widget getSecondStep() {
        return  Scrollbar(
          controller: ScrollController(),
          child: ListView(
              shrinkWrap: true,
              children: <Widget>[
                Row(
                  mainAxisSize: MainAxisSize.min,
                  mainAxisAlignment: MainAxisAlignment.center,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: <Widget>[BlaBlaBla(), BlaBla()],
                ),
              ],
            ),
        );
      }

我正在尝试更改主题颜色，但没有用。

最后， flutter doctor -v
