Answer 2

i think use of Positioned Widget can help to set Progress bar at dock

new Positioned(
       left: 30.0,
       top: 30.0,
       child: new Container(
         width: 100.0,
         height: 80.0,
         decoration: new BoxDecoration(color: Colors.red),
         child: new Text('hello'),
        )
      ),

And this will help to create round circle
