Like heart

A like button that springs and bursts a ring + sparks when favourited.

Installation

caveui components are copy-paste Jetpack Compose built entirely on Material 3 — there's no caveui dependency to add. Make sure Material 3 is on your classpath (it ships with the Compose BOM), then copy the Usage snippet below into your project.

kotlin

// build.gradle.kts (module)
dependencies {
    implementation(platform("androidx.compose:compose-bom:2025.06.00"))
    implementation("androidx.compose.material3:material3")
}

Usage

kotlin

@Composable
fun LikeHeart(liked: Boolean, onClick: () -> Unit) {
    val scale by animateFloatAsState(
        if (liked) 1f else 0.9f,
        spring(dampingRatio = Spring.DampingRatioMediumBouncy, stiffness = 500f),
        label = "like",
    )
    val burst by animateFloatAsState(if (liked) 1f else 0f, tween(450), label = "burst")
    Box(Modifier.size(40.dp).clickable(onClick = onClick), contentAlignment = Alignment.Center) {
        if (burst > 0f && burst < 1f) {
            Canvas(Modifier.matchParentSize()) {
                drawCircle(
                    color = Color(0xFFE11D48).copy(alpha = 1f - burst),
                    radius = size.minDimension / 2 * burst,
                    style = Stroke(2.dp.toPx()),
                )
            }
        }
        Icon(
            if (liked) Icons.Filled.Favorite else Icons.Outlined.FavoriteBorder,
            contentDescription = "Like",
            tint = if (liked) Color(0xFFE11D48) else LocalContentColor.current,
            modifier = Modifier.scale(scale),
        )
    }
