Notification ring

A bell that swings like a ringer while its unread count pops.

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 = "ring")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 0f,
    animationSpec = infiniteRepeatable(
        keyframes {
            durationMillis = 1800
            0f at 0
            (-12f) at 700
            12f at 800
            (-9f) at 900
            6f at 1000
            0f at 1100
        },
    ),
    label = "angle",
)
BadgedBox(
    badge = {
        Badge(containerColor = Color(0xFFEF4444), contentColor = Color.White) {
            Text("3", fontSize = 10.sp)
        }
    },
) {
    Icon(
        Icons.Outlined.Notifications,
        contentDescription = "Alerts",
        modifier = Modifier.graphicsLayer {
            rotationZ = angle
            transformOrigin = TransformOrigin(0.5f, 0.15f)
        },
    )
}
