Clock

A bordered circle with a single hand sweeping a full rotation.

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 = "clock")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 360f,
    animationSpec = infiniteRepeatable(tween(2000, easing = LinearEasing)),
    label = "angle",
)
val primary = MaterialTheme.colorScheme.primary
val track = MaterialTheme.colorScheme.surfaceVariant
Canvas(Modifier.size(32.dp)) {
    drawCircle(color = track, style = Stroke(width = 2.dp.toPx()))
    rotate(angle) {
        drawLine(
            color = primary,
            start = center,
            end = Offset(center.x, center.y - size.minDimension * 0.32f),
            strokeWidth = 2.dp.toPx(),
            cap = StrokeCap.Round,
        )
    }
}
