Implementation

@override
Widget buildTransitions(
  BuildContext context,
  Animation<double> animation,
  Animation<double> secondaryAnimation,
  Widget child,
) {
  var _alignment = Alignment(0, 0);
  if (tapDetails != null) {
    final _converter = CoordinatesToAlignment(
      point: tapDetails!.globalPosition,
      screenSize: MediaQuery.of(context).size,
    );
    _alignment = _converter.convert();
  }
  return FadeTransition(
    opacity: animation,
    child: ScaleTransition(
      scale: animation,
      child: child,
      alignment: _alignment,
    ),
  );
}
