build method

  1. @override
Widget build(
  1. 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) {
  return ClipRect(
    child: Align(
      alignment: switch (axis) {
        Axis.horizontal => AlignmentDirectional(axisAlignment, -1.0),
        Axis.vertical   => AlignmentDirectional(-1.0, axisAlignment),
      },
      heightFactor: axis == Axis.vertical ? math.max(sizeFactor.value, 0.0) : fixedCrossAxisSizeFactor,
      widthFactor: axis == Axis.horizontal ? math.max(sizeFactor.value, 0.0) : fixedCrossAxisSizeFactor,
      child: child,
    ),
  );
}
