zhelenskiy / animatecontentsingledimension

Description

This project is a tiny Kotlin Multiplatform Compose library that provides animateContentHeight and animateContentWidth functions which are similar to the existing androidx.compose.animation.animateContentSize but affects only one dimension. They reuse implementation of the latter one.

Use case

Some content might fillContentWidth but have variable height which should be animated. In this case standard animateContentSize would lead to unintended dragging during changing width, so you need animateContentHeight. The same thing is with animateContentWidth.

API

fun Modifier.animateContentHeight(
    animationSpec: FiniteAnimationSpec<Int> = spring(),
    finishedListener: ((initialValue: Int, targetValue: Int) -> Unit)? = null
): Modifier 

fun Modifier.animateContentWidth(
    animationSpec: FiniteAnimationSpec<Int> = spring(),
    finishedListener: ((initialValue: Int, targetValue: Int) -> Unit)? = null
): Modifier
