Can't set ListView into LayoutBuilder Widget (Flutter)

Question

I need to have some structure like this

I use LayoutBuilder to get the height of content (between App Bar and TabsBottomNavigation). Here i build Profile Info Container and want to build ListView with some List Tiles, but when I try to build it in Layout Builder I have errors in console.

If I create ListView out of LayoutBuilder it works!

Please help me to solve it. My code below:

Widget build(BuildContext context) {
    return LayoutBuilder(
      builder: (BuildContext context, BoxConstraints viewportConstraints) {
        return SingleChildScrollView(
          child: Container(
            child: Column(
              children: <Widget>[
                Container(
                  height: viewportConstraints.maxHeight * .44,
                  color: Theme.of(context).primaryColor,
                  padding: EdgeInsets.only(bottom: 2),
                  child: Align(
                    child: Column(
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: <Widget>[
                        _buildProfileImage(context),
                        SizedBox(height: 17),
                        Text(userName)
                      ],
                    ),
                  ),
                ),
                Expanded(
                  child: ListView(
                    children: <Widget>[
                      ListTile(
                        leading: Icon(Icons.print),
                        title: Text('asdad'),
                      )
                    ],
                  ),
                )
              ],
            ),
          ),
        );
      },
    );
  }

Use below build method will work in your case. (I have checked and it's working, so I hope it will work in your case also and will fit in your requirement.)

Widget build(BuildContext context) {
    return LayoutBuilder(
      builder: (BuildContext context, BoxConstraints viewportConstraints) {
        return Container(
          child: Column(
            children: <Widget>[
              Container(
                height: viewportConstraints.maxHeight * .44,
                color: Theme.of(context).primaryColor,
                padding: EdgeInsets.only(bottom: 2),
                child: Align(
                  child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    children: <Widget>[
                      _buildProfileImage(context),
                      SizedBox(height: 17),
                      Text(userName),
                    ],
                  ),
                ),
              ),
              SizedBox(height: 16),
              Flexible(
                child: ListView(
                  children: <Widget>[
                    Card(
                      child: ListTile(
                        leading: Icon(Icons.print),
                        title: Text('asdad'),
                      ),
                    ),
                  ],
                ),
              ),
            ],
          ),
        );
      },
    );
  }

I think SingleChildScrollView is of no use in this case so I removed it but you can use it if you fill so.

You still need to do some UI improvement as per your wish as this is the basic structure as per your requirement.

Hope this will help you.

You are using the LayoutBuilder in a wrong way.
It's supposed to be used to change the layout with the size of the device and/or orientation.

What you are trying to do is best accomplished with MediaQuery:

MediaQuery.of(context).padding.top //APP bar height
MediaQuery.of(context).padding.bottom //Bottom bar height
MediaQuery.of(context).size.height //Screen height
