expandVertically

This expands the clip bounds of the appearing content vertically, from the height returned from [initialHeight] to the full height.

Common

public fun expandVertically(
    animationSpec: FiniteAnimationSpec<IntSize> =
        spring(
            stiffness = Spring.StiffnessMediumLow,
            visibilityThreshold = IntSize.VisibilityThreshold,
        ),
    expandFrom: Alignment.Vertical = Alignment.Bottom,
    clip: Boolean = true,
    initialHeight: (fullHeight: Int) -> Int = { 0 },
): EnterTransition

This expands the clip bounds of the appearing content vertically, from the height returned from initialHeight to the full height. expandFrom controls which part of the content gets revealed first. By default, the clip bounds animates from 0 to full height, revealing the bottom edge first, followed by the rest of the content.

Note: expandVertically animates the bounds of the content. This bounds change will also result in the animation of other layouts that are dependent on this size.

initialHeight is a lambda that takes the full height of the content and returns an initial height of the bounds of the content. This allows not only an absolute height, but also an initial height that is proportional to the content height.

clip defines whether the content outside of the animated bounds should be clipped. By default, clip is set to true, which only shows content in the animated bounds.

Parameters


animationSpec	the animation used for the expanding animation, `spring` by default.
expandFrom	the starting point of the expanding bounds, `Alignment.Bottom` by default.
clip	whether the content outside of the animated bounds should be clipped, true by default
initialHeight	the start height of the expanding bounds, returning 0 by default.
