     width: 50.0,
     height: 50.0,
     color: Colors.blue,
   ),
   onTapUp: (TapUpDetails tapDetails) {
     final _converter = CoordinatesToAlignment(
       point: tapDetails.globalPosition,
       screenSize: MediaQuery.of(context).size,
     );
     final _alignment = _converter.convert();

     print('Coordinates have been converted into Alignment');
     print('Alignment.x = ' + _alignment.x?.toString());
     print('Alignment.y = ' + _alignment.y?.toString());
   },
 );
