Coupon apply

Promo-code field with an inline Apply button that flips to a success state.

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

var code by remember { mutableStateOf("") }
var applied by remember { mutableStateOf(false) }
OutlinedTextField(
    value = code,
    onValueChange = { code = it.uppercase() },
    placeholder = { Text("Promo code") },
    trailingIcon = {
        if (applied) {
            Icon(
                Icons.Filled.CheckCircle,
                contentDescription = "Applied",
                tint = Color(0xFF16A34A),
            )
        } else {
            TextButton(onClick = { applied = true }) { Text("Apply") }
        }
    },
    singleLine = true,
)
