SizedOverflowBox class

A widget that is a specific size but passes its original constraints through to its child, which may then overflow.

See also:

  • OverflowBox, A widget that imposes different constraints on its child than it gets from its parent, possibly allowing the child to overflow the parent.
  • ConstrainedBox, a widget that imposes additional constraints on its child.
  • UnconstrainedBox, a container that tries to let its child draw without constraints.
  • The catalog of layout widgets.
