Segmented bar

Three rounded segments that brighten in a left-to-right cycle.

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 = "segments")
Row(
    modifier = Modifier.width(160.dp),
    horizontalArrangement = Arrangement.spacedBy(4.dp),
) {
    repeat(3) { i ->
        val alpha by t.animateFloat(
            initialValue = 0.25f,
            targetValue = 1f,
            animationSpec = infiniteRepeatable(
                tween(500, delayMillis = i * 250),
                RepeatMode.Reverse,
            ),
            label = "alpha",
        )
        Box(
            Modifier
                .weight(1f)
                .height(6.dp)
                .graphicsLayer { this.alpha = alpha }
                .background(MaterialTheme.colorScheme.primary, RoundedCornerShape(50)),
        )
    }
}
