Play Morph

Circular button cross-fading between play and pause transport glyphs.

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 PlayPauseButton() {
  var playing by remember { mutableStateOf(true) }
  FilledIconToggleButton(
    checked = playing,
    onCheckedChange = { playing = it },
  ) {
    AnimatedContent(targetState = playing, label = "play") {
      Icon(
        imageVector = if (it)
          Icons.Filled.Pause
        else
          Icons.Filled.PlayArrow,
        contentDescription = null,
      )
    }
  }
}
