IncularAPI ReferenceLayout Widgets
Visibility & Offstage
Conditional display with state, size, animation, and semantics retention.
Visibility conditionally displays its child; preservation flags imply
retention of the hidden subtree. Offstage hides without unmounting:
measured, but no paint, hit-test, or semantics.
