ExitTransitionSchema

@Serializable

Exit transition applied when a screen or animated content leaves the composition.

Multiple variants can coexist in ContentTransitionSchema.exit — they are combined with the + operator to run simultaneously (e.g. fade + slide).

Variants:

FadeOut — fadeOut(animationSpec, targetAlpha). Default: alpha 1f → 0f over 300ms.
SlideOutHorizontally — slideOutHorizontally(animationSpec, targetOffsetX). Default offset: OffsetType.NegativeFull (slides out to the left).
SlideOutVertically — slideOutVertically(animationSpec, targetOffsetY). Default offset: OffsetType.NegativeFull (slides out upward).
KeepUntilTransitionsFinished — currently maps to ExitTransition.None in the client (AnimationSchemaExtensions). The TODO comment indicates this should use ExitTransition.KeepUntilTransitionsFinished once it becomes stable public API.
None — ExitTransition.None (no animation).

How OffsetType maps to pixel offset (lambda { fullSize }):

OffsetType.Full → +fullSize (exits to right/bottom)
OffsetType.NegativeFull → -fullSize (exits to left/top — default for slide-out)
OffsetType.Fixed → exact pixel value
OffsetType.Fraction → (fullSize * factor).toInt()
