paintStack method Null safety

  1. @override
void paintStack(
  1. PaintingContext context,
  2. Offset offset
)
override

Override in subclasses to customize how the stack paints.

By default, the stack uses defaultPaint. This function is called by paint after potentially applying a clip to contain visual overflow.

Implementation

@override
void paintStack(PaintingContext context, Offset offset) {
  if (firstChild == null || index == null)
    return;
  final RenderBox child = _childAtIndex();
  final StackParentData childParentData = child.parentData! as StackParentData;
  context.paintChild(child, childParentData.offset + offset);
}
