paintChildren abstract method
- 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.
Implementation
void paintChildren(FlowPaintingContext context);
