flutter - 当我在Stack(Positioned)中使用ListView时发生问题

Question

我想在屏幕上显示三件事，一个显示日期的时间表，一个包含几个ListView的Container，并在屏幕底部显示一个导航栏。之所以将它们放在Stack中，是因为ListView比屏幕尺寸长，我不想让它阻塞导航栏。我的问题是关于ListView的内容根本不显示，因此底部导航栏为空白。我试图用ListView替换Column，它可以工作，但不是我想要的。和错误=

RenderBox was not laid out: RenderRepaintBoundary#40da3relayoutBoundary=up2 NEEDS-PAINT'package:flutter/src/rendering/box.dart': Failed assertion: line 1694pos 12: 'hasSize'

body: Stack(
          children: <Widget>[
            Positioned(
              top: 0,
              child: timeTable(),
            ),
            Positioned(
              top: 114.0,
              height: 200,
              child: ListView(
                children: <Widget>[
                  Container(height: 100,),
                  Container(height: 100,),
                ],
              )
            ),
            Positioned(
              bottom: 0,
              child: NavigationBar(),
            ),
          ],
        ),

下面是关于timeTable()类

    Widget timeTable() {
  return Container(
    height: 98.0,
    width: 540.0,
    margin: EdgeInsets.only(left: 114.0, right: 114.0),
    child: Column(
      children: <Widget>[
        SizedBox(height: 24.0,),
        Container(
          height: 24.0,
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: <Widget>[
              Container(
                child: Text('日付', style: StatisticTextStyle.date, ),
              ),
              stuckButtons(),
            ],
          ),
        ),
        Container(
          padding: EdgeInsets.only(bottom: 0),
          height: 44,
          child: Container(
            alignment: Alignment.bottomRight,
            padding: EdgeInsets.only(top: 0),
            child: RichText(
              text: TextSpan(
                children: [
                  TextSpan(
                    text: "2020年10月15日 ",
                    style: StatisticTextStyle.mainText,
                  ),
                  WidgetSpan(
                    // make the icon higher so that alignment with the text.
                    child: Container(
                      padding: EdgeInsets.only(bottom: 2),
                      child: MyIcon.calendarIcon,
                    )
                  ),
                ],
              ),
            ),
          ),
        ),
      ],
    ),
  );
}

Answer 1

我已经解决了问题。
我选择Stack的原因是关于自定义底部导航栏，因为小部件属于主体。实际上，我们可以在Scaffold中使用bottomNavigationBar。
因此剩下的问题是如何维护窗口小部件和ListView中的Column以显示在屏幕上。
新的错误信息=

The following assertion was thrown during performResize(): Verticalviewport was given unbounded height.it's not difficult to find we should give the ListView a height. Put the ListView into a container and set the height of the container then it will be Okay.
