Credit card

Card number field that auto-groups digits and shows the detected brand icon.

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 card by remember { mutableStateOf("") }
val grouped = card.chunked(4).joinToString(" ")

    value = grouped,
    onValueChange = {
        card = it.filter(Char::isDigit).take(16)
    },
    leadingIcon = {
