Episode 12 — Signals

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 BufferedScrubber() {
  val played by animateFloatAsState(
    targetValue = 0.4f,
    animationSpec = tween(700),
    label = "p",
  )
  val buffered = 0.72f
  Card(
    shape = RoundedCornerShape(18.dp),
    modifier = Modifier.fillMaxWidth(),
  ) {
    Column(Modifier.padding(16.dp)) {
      Text("Episode 12 — Signals",
        style = MaterialTheme.typography.titleSmall)
      Spacer(Modifier.height(14.dp))
      Box(
