Stack Widget Error when using SingleChildScrollView

I have this code as profile screen which I need it to be able to fill a text like "HELLO" on this code example. But when I put a lot of text in it, the screen become overflow. The problem is everytime I put SingleChildScrollView to avoid the overflow, I got another error instead. Please tell me how I can fix this problem.

  @override
  Widget build(BuildContext context) {
    return Container(
        child: SafeArea(
          child: FutureBuilder<Profile>(
            future: dataService.getHttp(),
            builder: ...
          ),
        ),
    );
  }

  Widget _buildView(detail) {
    return Stack(
        alignment: Alignment.center,
        children: <Widget>[
          Column(
            children: <Widget>[
              Container(
                height: 200.0,
                child: Center(
                  child: Image.network( 
                    'https://i.imgur.com/2F3Al82.jpg', 
                    fit: BoxFit.cover,
                    height: double.infinity,
                    width: double.infinity,
                  ),
                ),
              ),
              Padding(
                padding: EdgeInsets.fromLTRB(0.0, 50.0, 0.0, 0.0),
              ),
              Expanded(
                child: Container(
                  color: Colors.white,
                  child: Column(
                    children: <Widget>[
                      Text('HELLO'),
                    ]
                  ),
                )
              ),
            ],
          ),
          Positioned(
            top: 150.0,
            child: Container(
              height: 100.0,
              width: 100.0,
              decoration: BoxDecoration(
                shape: BoxShape.circle,
                image: new DecorationImage(
                  fit: BoxFit.fill,
                  image: NetworkImage('https://i.imgur.com/2F3Al82.jpg'),
                ),
              ),
            ),
          )
        ],

You are getting this error because of the Expanded widget. SingleChildScrollView allows for infinite height and expanded will take up as much space as it can these two thing are incompatible if you remove the Expanded widget it should work. If you want some space around that container I suggest the Containers margin property.
