Spiral

Dots set along a spiral arm, fading outward as the whole shape turns.

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 = "spiral")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 360f,
    animationSpec = infiniteRepeatable(tween(1400, easing = LinearEasing)),
    label = "angle",
)
val color = MaterialTheme.colorScheme.primary
Canvas(Modifier.size(36.dp).rotate(angle)) {
    val count = 7
    repeat(count) { i ->
        val frac = i / count.toFloat()
        val rad = Math.toRadians((i * 60).toDouble())
        val dist = (size.minDimension / 2f) * (0.3f + 0.7f * frac)
        drawCircle(
            color = color.copy(alpha = 1f - frac * 0.8f),
            radius = (1.5f + 2f * (1f - frac)).dp.toPx(),
            center = center + Offset(
                (dist * cos(rad)).toFloat(),
                (dist * sin(rad)).toFloat(),
            ),
        )
    }
}
