build method

  1. @override
Widget build (BuildContext context)
override

Override this method to build widgets that depend on the state of the listenable (e.g., the current value of the animation).

Implementation 

@override
Widget build(BuildContext context) {
  Offset offset = position.value;
  if (textDirection == TextDirection.rtl)
    offset = Offset(-offset.dx, offset.dy);
  return FractionalTranslation(
    translation: offset,
    transformHitTests: transformHitTests,
    child: child,
  );
}
