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
@Composable
fun BatterySaver(charging: Boolean) {
    val glow by rememberInfiniteTransition().animateFloat(
        initialValue = 0.5f,
        targetValue = 1f,
        animationSpec = infiniteRepeatable(
            tween(800), RepeatMode.Reverse
        )
    )
    Surface(
        shape = RoundedCornerShape(14.dp),
        color = Color(0xFFDCFCE7),
        modifier = Modifier.padding(12.dp)
    ) {
        Row(
            modifier = Modifier.padding(16.dp),
            verticalAlignment = Alignment.CenterVertically,
            horizontalArrangement = Arrangement.spacedBy(12.dp)
        ) {
            Icon(
                Icons.Rounded.BatteryChargingFull,
                contentDescription = null,
                tint = Color(0xFF16A34A).copy(
