This is based on the @Joe answer but it has more accurated pin position and no other class is required:

double mapWidth = MediaQuery.of(context).size.width;
double mapHeight = MediaQuery.of(context).size.height - 215;
double iconSize = 40.0;

return new Stack(
    alignment: Alignment(0.0, 0.0),
    children: [
      new Container(
        width: mapWidth,
        height: mapHeight,
        child: _googleMap
      ),
      new Positioned(
        top: (mapHeight - iconSize)/ 2,
        right: (mapWidth - iconSize)/ 2,
        child: new Icon(Icons.person_pin_circle, size: iconSize),
      )
  ]);

This solution don't require to repaint the entire Screen (no setState call) when user update the position. You won't see that weird marker "movement".
