Dual Tone

Switch whose track splits into two contrasting color halves.

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 DualToneToggle() {
  var on by remember { mutableStateOf(true) }
  val offset by animateDpAsState(
    targetValue = if (on) 20.dp else 0.dp,
    label = "offset",
  )
  Box(
    modifier = Modifier
      .width(52.dp)
      .height(32.dp)
      .clip(CircleShape)
      .clickable { on = !on },
  ) {
    Row(Modifier.fillMaxSize()) {
      Box(
        Modifier
          .weight(1f)
          .fillMaxHeight()
          .background(Color(0xFFF43F5E)),
      )
      Box(
        Modifier
          .weight(1f)
          .fillMaxHeight()
          .background(Color(0xFF10B981)),
      )
    }
    Box(
      Modifier
        .padding(4.dp)

        .size(24.dp)
