Play / Pause

A circular transport button that toggles between play and pause icons.

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 playing by remember { mutableStateOf(false) }
FilledIconButton(
    onClick = { playing = !playing },
    modifier = Modifier.size(56.dp),
) {
    AnimatedContent(playing, label = "play") { on ->
        if (on) Icon(Icons.Filled.Pause, contentDescription = "Pause")
        else Icon(Icons.Filled.PlayArrow, contentDescription = "Play")
    }
}
