Avatarsanimated

Live sweep

An avatar in a slowly rotating conic gradient ring for an active broadcast.

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 LiveSweepAvatar(initials: String) {
    val rotation by rememberInfiniteTransition(label = "sweep")
        .animateFloat(
            initialValue = 0f, targetValue = 360f,
            animationSpec = infiniteRepeatable(tween(2600, easing = LinearEasing)),
            label = "rot",
        )
    val sweep = Brush.sweepGradient(
        listOf(Color(0xFFF59E0B), Color(0xFFE11D48), Color(0xFF8B5CF6), Color(0xFFF59E0B)),
    )
    val bg = MaterialTheme.colorScheme.background
    Box(
        Modifier.size(60.dp).graphicsLayer { rotationZ = rotation }
            .clip(CircleShape).background(sweep),
        contentAlignment = Alignment.Center,
    ) {
        Box(
            Modifier.size(54.dp).graphicsLayer { rotationZ = -rotation }
                .clip(CircleShape).background(bg).padding(3.dp)
                .clip(CircleShape).background(MaterialTheme.colorScheme.surfaceVariant),
            contentAlignment = Alignment.Center,
        ) {
            Text(initials, style = MaterialTheme.typography.titleMedium)
        }
    }
}
