Rainbow ring

A multi-hue conic ring rotating smoothly through the full spectrum.

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 = "rainbow")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 360f,
    animationSpec = infiniteRepeatable(tween(1500, easing = LinearEasing)),
    label = "angle",
)
val colors = listOf(
    Color(0xFFF43F5E), Color(0xFFF59E0B), Color(0xFF10B981),
    Color(0xFF0EA5E9), Color(0xFF8B5CF6), Color(0xFFF43F5E),
)
Canvas(Modifier.size(36.dp).rotate(angle)) {
    drawCircle(
        brush = Brush.sweepGradient(colors),
        radius = size.minDimension / 2f - 2.dp.toPx(),
        style = Stroke(width = 4.dp.toPx()),
    )
}
