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 value by remember { mutableStateOf("") }
val max = 30
OutlinedTextField(
    value = value,
    onValueChange = { if (it.length <= max) value = it },
    placeholder = { Text("Display name") },
    supportingText = {
        Text(
            "${value.length} / $max",
            modifier = Modifier.fillMaxWidth(),
            textAlign = TextAlign.End,
        )
    },
    singleLine = true,
)
