Dot spinner

Eight dots arranged in a ring, fading around as it rotates.

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 = "dotspin")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 360f,
    animationSpec = infiniteRepeatable(tween(1000, easing = LinearEasing)),
    label = "angle",
)
val color = MaterialTheme.colorScheme.primary
Canvas(Modifier.size(32.dp).rotate(angle)) {
    val count = 8
    val r = size.minDimension / 2f - 3.dp.toPx()
    repeat(count) { i ->
        val rad = Math.toRadians((i * 360.0 / count))
        drawCircle(
            color = color.copy(alpha = (i + 1) / count.toFloat()),
            radius = 2.5.dp.toPx(),
            center = center + Offset((r * cos(rad)).toFloat(), (r * sin(rad)).toFloat()),
        )
    }
}
