Try wrap your container into a Column and use axis align properties.
Stack(
overflow: Overflow.visible,
children: <Widget>[
Container(
//width: MediaQuery.of(context).size.width, In my test this line causes bad behavior
height: 170,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(0),
bottomRight: Radius.circular(0))),
// child: Image.network(tutorImage),
),
Column(
mainAxisAlignment: MainAxisAlignment.end, // start at end/bottom of column
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Center( // center in horizontal axis
child: Container(
width: 60,
height: 60,
color: Colors.black,

To be sincere I've never used Align widgets. I always make alignment with axis properties and Flex factors. Anyway after your question update now it's more clear what kind of effect you want and the column approach will not work in this case. Sorry about it.
