Add Toggle

Round button morphing a plus into a check when an item adds.

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 AddToggle() {
  var added by remember { mutableStateOf(true) }
  IconToggleButton(
    checked = added,
    onCheckedChange = { added = it },
  ) {
    Box(
      contentAlignment = Alignment.Center,
      modifier = Modifier
        .size(28.dp)
        .clip(CircleShape)
        .background(
          if (added) MaterialTheme.colorScheme.primary
          else MaterialTheme.colorScheme.surfaceVariant,
        ),
    ) {
      AnimatedContent(targetState = added, label = "add") {
        Icon(
          imageVector = if (it) Icons.Default.Check
            else Icons.Default.Add,
          contentDescription = null,
          tint = if (it)
            MaterialTheme.colorScheme.onPrimary
          else
            MaterialTheme.colorScheme.onSurfaceVariant,
          modifier = Modifier.size(16.dp),
        )
      }
    }
  }
