Package-level declarations

Models a typical "You sure about that?" alert box.

Informs views whether they're children of a BackStackScreen, and if so whether they're the first frame or not.

Represents an active screen (top), and a set of previously visited screens to which we may return (backStack). By rendering the entire history we allow the UI to do things like maintain cached view state, implement drag-back gestures without waiting for the workflow, etc.

A screen that may stack a number of Overlays over a body. If any members of overlays are ModalOverlay, the body and lower-indexed members of that list are expected to ignore input events -- touch, keyboard, etc.

A basic ScreenOverlay that covers its container with the wrapped content.

Marker interface identifying Overlay renderings whose presence indicates that events are blocked from lower layers.

Marker interface implemented by window-like renderings that map to a layer above a base Screen by being placed in a BodyAndOverlaysScreen.overlays list. See BodyAndOverlaysScreen for more details.

An Overlay built around a root content.

Returns a new BackStackScreen with the BackStackScreen.frames of other added to those of the receiver. other is nullable for convenience when using with toBackStackScreenOrNull.
