Fill Radio

Selected option becomes a fully filled solid disc for strong emphasis.

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 FillRadioGroup() {
  var selected by remember { mutableStateOf(1) }
  Row(horizontalArrangement = Arrangement.spacedBy(12.dp)) {
    repeat(3) { index ->
      val active = index == selected
      Box(
        modifier = Modifier
          .size(24.dp)
          .clip(CircleShape)
          .background(
            if (active)
              MaterialTheme.colorScheme.primary
            else
              Color.Transparent,
          )
          .border(
            2.dp,
            MaterialTheme.colorScheme.outline,
            CircleShape,
          )
          .clickable { selected = index },
      )
    }
  }
}
