Flashlight

Flashlight toggle glowing warm amber when the torch turns 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 FlashlightToggle() {
  var on by remember { mutableStateOf(true) }
  val glow by animateDpAsState(
    targetValue = if (on) 16.dp else 0.dp,
    label = "glow",
  )
  val amber = Color(0xFFFBBF24)
  FilledTonalIconToggleButton(
    checked = on,
    onCheckedChange = { on = it },
    modifier = Modifier.shadow(
      elevation = glow,
      shape = CircleShape,
      ambientColor = amber,
      spotColor = amber,
    ),
  ) {
    Icon(
      imageVector = if (on)
        Icons.Filled.FlashlightOn
      else
        Icons.Filled.FlashlightOff,
      contentDescription = null,
      tint = if (on) amber
        else MaterialTheme.colorScheme.onSurfaceVariant,
    )
  }
