Square Knob

Switch with a squared track and a sliding rounded-square knob.

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 SquareKnobToggle() {
  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(RoundedCornerShape(8.dp))
      .background(
        if (on) MaterialTheme.colorScheme.primary
        else MaterialTheme.colorScheme.surfaceVariant,
      )
      .clickable { on = !on }
      .padding(4.dp),
    contentAlignment = Alignment.CenterStart,
  ) {
    Box(
      Modifier
        .offset(x = offset)
        .size(24.dp)
        .clip(RoundedCornerShape(6.dp))
        .background(Color.White),
    )
  }
}
