Converts the global position at which the pointer contacted the screen into Alignment. Call the convert() method is required to finish converting.

It uses tap details provided by GestureDetector or another GestureRecognizerFactory.

   child: Container(
     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());
   },
 );
