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

val t = rememberInfiniteTransition(label = "eq")
Surface(
    shape = RoundedCornerShape(50),
    color = Color(0xFF8B5CF6).copy(alpha = 0.14f),
    contentColor = Color(0xFF7C3AED),
) {
    Row(
        Modifier.padding(start = 8.dp, end = 10.dp, top = 4.dp, bottom = 4.dp),
        verticalAlignment = Alignment.CenterVertically,
        horizontalArrangement = Arrangement.spacedBy(6.dp),
    ) {
        Row(
            verticalAlignment = Alignment.Bottom,
            horizontalArrangement = Arrangement.spacedBy(2.dp),
        ) {
            repeat(4) { i ->
                val h by t.animateFloat(
                    initialValue = 0.3f,
                    targetValue = 1f,
                    animationSpec = infiniteRepeatable(
                        tween(420 + i * 90),
                        RepeatMode.Reverse,
                    ),
                    label = "bar",
                )
                Box(
                    Modifier
                        .width(2.5.dp)
                        .height(12.dp)
                        .graphicsLayer { scaleY = h; transformOrigin = TransformOrigin(0.5f, 1f) }
                        .background(Color(0xFF7C3AED), RoundedCornerShape(2.dp)),
                )
            }
        }
        Text("Now playing", fontSize = 12.sp, fontWeight = FontWeight.Medium)
    }
