Package-level declarations

Types

Contains default values used for the bottom app bar implementations.

class SparkBottomAppBarScrollBehavior(val state: BottomAppBarState, val snapAnimationSpec: AnimationSpec<Float>?, val flingAnimationSpec: DecayAnimationSpec<Float>?, val canScroll: () -> Boolean = { true }) : BottomAppBarScrollBehavior

Scroll behavior for BottomAppBar that implements a pinned behavior similar to TopAppBar but with bottom-specific elevation logic. The bottom app bar stays pinned at the bottom and shows elevation when content has been scrolled up from a scrolled-down position (contentOffset 0), indicating there's content above the current scroll position.

TopAppBarColors

@Stable

class TopAppBarColors

Represents the colors used by a top app bar in different states. This implementation animates the container color according to the top app bar scroll state. It does not animate the leading, headline, or trailing colors.

TopAppBarSparkDefaults

object TopAppBarSparkDefaults

Contains default values used for the top app bar implementations.
