Check Radio

Circular radio that reveals a checkmark glyph when its option is selected.

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 CheckRadioGroup() {
  var selected by remember { mutableStateOf(0) }
  Column(verticalArrangement = Arrangement.spacedBy(8.dp)) {
    repeat(3) { index ->
      val active = index == selected
      Box(
        contentAlignment = Alignment.Center,
        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 },
      ) {
        if (active) {
          Icon(
            imageVector = Icons.Default.Check,
            contentDescription = null,
            tint = MaterialTheme.colorScheme.onPrimary,
            modifier = Modifier.size(16.dp),
          )
        }
      }
    }
  }
