Power Button

Round power button gaining a green ring when switched on.

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 PowerButtonToggle() {
  var on by remember { mutableStateOf(true) }
  val ring by animateColorAsState(
    targetValue = if (on)
      Color(0xFF22C55E)
    else
      MaterialTheme.colorScheme.outline,
    label = "ring",
  )
  Box(
    contentAlignment = Alignment.Center,
    modifier = Modifier
      .size(40.dp)
      .clip(CircleShape)
      .border(2.dp, ring, CircleShape)
      .clickable { on = !on },
  ) {
    Icon(
      imageVector = Icons.Filled.PowerSettingsNew,
      contentDescription = null,
      tint = ring,
      modifier = Modifier.size(20.dp),
    )
