flutter - Android、iOS 和 web 中的“A RenderFlex 底部溢出 21 个像素”

Question

我一直在尝试修复错误，但作为 Flutter 的新手，我无法做到这一点。它不断消除错误。我尝试使用一些 Stack Overflow 答案修复它，但不能。

这是代码

@override
  Widget build(BuildContext context) {
    return Scaffold(backgroundColor: Color(0xfff1f3f6), 
      body: Stack(children: [ Column(children: [
              Row(mainAxisAlignment: MainAxisAlignment.spaceBetween, children: [
                  Container(height: 150, width: MediaQuery.of(context).size.width*0.6, decoration: BoxDecoration(borderRadius: BorderRadius.only(bottomRight: Radius.circular(60)), color: Colors.white),
                    child: Center(child: Row(mainAxisAlignment: MainAxisAlignment.center, children: [
                          Container(width: 50, height: 50, decoration: BoxDecoration(shape: BoxShape.circle, color: Color(0xfff1f3f6), image: DecorationImage(image: AssetImage('asset/images/avatar4.png'), fit: BoxFit.contain))),
                          SizedBox(width: 10,),
                          Column(mainAxisAlignment: MainAxisAlignment.center, crossAxisAlignment: CrossAxisAlignment.start, children: [
                              Text("Carol Johnson", style: TextStyle(fontSize: 19, fontWeight: FontWeight.w700),),
                              Text("Seattle Washington", style: TextStyle(fontSize: 13, fontWeight: FontWeight.w400, color: Colors.grey
                              ),)
                            ],
                          )
                        ],
                      ),
                    ),
                  )
                ],
              ),
              Expanded(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center, children: [
                    navigatorTitle("Home", true),
                    navigatorTitle("Profile", false),
                    navigatorTitle("Accounts", false),
                    navigatorTitle("Transactions", false),
                    navigatorTitle("Stats", false),
                    navigatorTitle("Settings", false),
                    navigatorTitle("Help", false),
                  ],
                ),
              ),
              Container(
                padding: EdgeInsets.all(20), child: Row(children: [Icon(Icons.power_settings_new, size: 30,),
                    Text("Logout", style: TextStyle(fontSize: 20, fontWeight: FontWeight.w700),)],),),
              Container(alignment: Alignment.bottomLeft, padding: EdgeInsets.all(20), child: Text("Ver 2.0.1",style: TextStyle(color: Colors.grey),),)],),
          AnimatedPositioned(
            duration: Duration(milliseconds: 200),
            left: (sideBarActive) ? MediaQuery.of(context).size.width*0.6 : 0,
            top: (sideBarActive)? MediaQuery.of(context).size.height*0.2 : 0,
            child: RotationTransition(
              turns: (sideBarActive) ? Tween(begin: -0.05, end: 0.0).animate(_rotationController) : Tween(begin: 0.0, end: -0.05).animate(_rotationController),
              child: AnimatedContainer(
                duration: Duration(milliseconds: 200),
                height: (sideBarActive) ? MediaQuery.of(context).size.height*0.7 : MediaQuery.of(context).size.height,
                width: (sideBarActive) ? MediaQuery.of(context).size.width*0.8 : MediaQuery.of(context).size.width,
                decoration: BoxDecoration(borderRadius: BorderRadius.all(Radius.circular(40)), color: Colors.white),
                child: ClipRRect(borderRadius: BorderRadius.all(Radius.circular(40)), child: HomePage(),),),),),
          Positioned(right: 0, top: 20, child: (sideBarActive) ? IconButton(padding: EdgeInsets.all(30), onPressed: closeSideBar,
              icon: Icon(Icons.close, color: Colors.black, size: 30,),): InkWell(onTap: openSideBar,
              child: Container(margin: EdgeInsets.all(17), height: 30, width: 30, decoration: BoxDecoration(image: DecorationImage(image: AssetImage('asset/images/menu.png'))),),

            ),
          )
        ],
      ),
    );
  }
  Row navigatorTitle(String name, bool isSelected)
  {
    return Row(
      children: [(isSelected) ? Container(width: 5, height: 60, color: Color(0xffffac30),):
        Container(width: 5, height: 60,),
        SizedBox(width: 10,height: 60,),
        Text(name, style: TextStyle(fontSize: 16, fontWeight: (isSelected) ? FontWeight.w700: FontWeight.w400),)],);
  }
  void closeSideBar()
  {
    sideBarActive = false;
    setState(() {

    });
  }
  void openSideBar()
  {
    sideBarActive = true;
    setState(() {

    });
  }

这是我得到的错误

======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 5.0 pixels on the right.

The relevant error-causing widget was: 
  Row file:///Users/wikiwoo/AndroidStudioProjects/etransfa/lib/christdoes/view/home_with_sidebar.dart:44:42
The overflowing RenderFlex has an orientation of Axis.horizontal.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.

Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.

The specific RenderFlex in question is: RenderFlex#3d9c3 relayoutBoundary=up1 OVERFLOWING
...  parentData: offset=Offset(0.0, 0.0) (can use size)
...  constraints: BoxConstraints(0.0<=w<=192.0, 0.0<=h<=150.0)
...  size: Size(192.0, 150.0)
...  direction: horizontal
...  mainAxisAlignment: center
...  mainAxisSize: max
...  crossAxisAlignment: center
...  textDirection: ltr
...  verticalDirection: down
