Avatarsanimated

Live pulse

An avatar with concentric pulse rings that signal a live or broadcasting state.

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 LivePulseAvatar(initials: String) {
    val accent = Color(0xFFE11D48)
    val transition = rememberInfiniteTransition(label = "pulse")
    val scale by transition.animateFloat(
        initialValue = 1f,
        targetValue = 1.7f,
        animationSpec = infiniteRepeatable(tween(1400), RepeatMode.Restart),
        label = "scale",
    )
    val alpha by transition.animateFloat(
        initialValue = 0.5f,
        targetValue = 0f,
        animationSpec = infiniteRepeatable(tween(1400), RepeatMode.Restart),
        label = "alpha",
    )
    Box(contentAlignment = Alignment.Center) {
        Box(
            Modifier
                .size(48.dp)
                .graphicsLayer {
                    scaleX = scale; scaleY = scale; this.alpha = alpha
                }
                .clip(CircleShape)
                .background(accent),
        )
        Box(
            Modifier.size(48.dp).clip(CircleShape)
                .background(MaterialTheme.colorScheme.surfaceVariant),
            contentAlignment = Alignment.Center,
        ) {
            Text(initials, style = MaterialTheme.typography.titleSmall)
        }
    }
