build method Null safety
- 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) {
final AlignmentDirectional alignment;
if (axis == Axis.vertical) {
alignment = AlignmentDirectional(-1.0, axisAlignment);
} else {
alignment = AlignmentDirectional(axisAlignment, -1.0);
}
return ClipRect(
child: Align(
alignment: alignment,
heightFactor: axis == Axis.vertical ? math.max(sizeFactor.value, 0.0) : null,
widthFactor: axis == Axis.horizontal ? math.max(sizeFactor.value, 0.0) : null,
child: child,
),
);
}
