paintChildren abstract method

void paintChildren(
  1. FlowPaintingContext context

Override to paint the children of the flow.

Children can be painted in any order, but each child can be painted at most once. Although the container clips the children to its own bounds, it is more efficient to skip painting a child altogether rather than having it paint entirely outside the container's clip.

To paint a child, call FlowPaintingContext.paintChild on the given FlowPaintingContext (the context argument). The given context is valid only within the scope of this function call and contains information (such as the size of the container) that is useful for picking transformation matrices for the children.

If this function depends on information other than the given context, override shouldRepaint to indicate when the container should relayout.


void paintChildren(FlowPaintingContext context);
