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 TimeSlots() {
    val slots = listOf("9:00", "9:30", "10:00", "10:30", "11:00", "11:30")
    val taken = setOf("10:00")
    var selected by remember { mutableStateOf("9:30") }
    FlowRow(maxItemsInEachRow = 3,
        horizontalArrangement = Arrangement.spacedBy(8.dp),
        verticalArrangement = Arrangement.spacedBy(8.dp)) {
        slots.forEach { s ->
            val isTaken = s in taken
            val on = s == selected
            OutlinedButton(
                onClick = { if (!isTaken) selected = s },
                enabled = !isTaken,
                colors = ButtonDefaults.outlinedButtonColors(
                    containerColor = if (on) MaterialTheme.colorScheme.primary
                        else Color.Transparent,
                    contentColor = if (on) MaterialTheme.colorScheme.onPrimary
                        else MaterialTheme.colorScheme.onSurface,
                ),
            ) { Text(s) }
        }
    }
