Glass

Frosted translucent switch blurring the surface behind its 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 GlassToggle() {
  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)
      .background(
        MaterialTheme.colorScheme.primary.copy(
          alpha = 0.18f,
        ),
      )
      .border(
        1.dp,
        Color.White.copy(alpha = 0.4f),
        CircleShape,
      )
      .clickable { on = !on }
      .padding(4.dp),
    contentAlignment = Alignment.CenterStart,
  ) {
    Box(
      Modifier
        .offset(x = offset)
        .size(24.dp)
        .clip(CircleShape)
        .background(Color.White.copy(alpha = 0.85f)),
    )
