Gradient sweep

A thick sweep-gradient arc rotating to suggest continuous activity.

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 = "sweep")
val angle by t.animateFloat(
    initialValue = 0f,
    targetValue = 360f,
    animationSpec = infiniteRepeatable(tween(1100, easing = LinearEasing)),
    label = "angle",
)
val c1 = MaterialTheme.colorScheme.primary
val c2 = MaterialTheme.colorScheme.tertiary
Canvas(Modifier.size(36.dp).rotate(angle)) {
    drawArc(
        brush = Brush.sweepGradient(listOf(c1, c2, c1)),
        startAngle = 0f,
        sweepAngle = 300f,
        useCenter = false,
        style = Stroke(width = 5.dp.toPx(), cap = StrokeCap.Round),
    )
}
