这行得通吗？

double _appBarHeight = 120, _imageHeight = 80, _iconTopMargin = 44, _iconLeftMargin = 12, _leftMargin = 120;

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Stack(
      children: <Widget>[
        Positioned(
          left: 0,
          right: 0,
          height: _appBarHeight,
          child: Container(color: Colors.blue),
        ),
        Positioned(
          left: _iconLeftMargin,
          top: _iconTopMargin,
          child: Icon(Icons.settings, color: Colors.white),
        ),
        Positioned(
          right: _iconLeftMargin,
          top: _iconTopMargin,
          child: Icon(Icons.bubble_chart, color: Colors.white),
        ),
        Positioned(

          top: _appBarHeight - _imageHeight / 2,
          child: ClipOval(child: Image.asset("assets/images/profile.jpg", fit: BoxFit.cover, height: _imageHeight, width: _imageHeight)),
