UnconstrainedBox class

A widget that imposes no constraints on its child, allowing it to render at its "natural" size.

This allows a child to render at the size it would render if it were alone on an infinite canvas with no constraints. This container will then attempt to adopt the same size, within the limits of its own constraints. If it ends up with a different size, it will align the child based on alignment. If the box cannot expand enough to accommodate the entire child, the child will be clipped.

In debug mode, if the child overflows the container, a warning will be printed on the console, and black and yellow striped areas will appear where the overflow occurs.

• Align, which loosens the constraints given to the child rather than removing them entirely.
• Container, a convenience widget that combines common painting, positioning, and sizing widgets.
• OverflowBox, a widget that imposes different constraints on its child than it gets from its parent, possibly allowing the child to overflow the parent.
• ConstraintsTransformBox, a widget that sizes its child using a transformed BoxConstraints, and shows a warning if the child overflows in debug mode.
