EnterTransitionSchema

@Serializable

Enter transition applied when a screen or animated content becomes visible.

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

Variants:

FadeIn — fadeIn(animationSpec, initialAlpha). Default: alpha 0f → 1f over 300ms.
SlideInHorizontally — slideInHorizontally(animationSpec, initialOffsetX). Default offset: OffsetType.Full (slides in from fully off-screen right).
SlideInVertically — slideInVertically(animationSpec, initialOffsetY). Default offset: OffsetType.Full (slides in from below).
None — EnterTransition.None (no animation; use to disable enter on one side of a pair).

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