FAB Menu

A FAB whose plus icon rotates into a close icon when its menu opens.

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

var open by remember { mutableStateOf(false) }
val rotation by animateFloatAsState(
    if (open) 135f else 0f,
    label = "fab",
)
FloatingActionButton(onClick = { open = !open }) {
    Icon(
        Icons.Filled.Add,
        contentDescription = if (open) "Close" else "Open",
        modifier = Modifier.graphicsLayer { rotationZ = rotation },
    )
}
