Fingerprint

Concentric fingerprint ridges that trace themselves in, resolving into an auth prompt.

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 FingerprintScan(progress: Float) { // 0f..1f
    val color = MaterialTheme.colorScheme.primary
    Canvas(Modifier.size(40.dp)) {
        val s = Stroke(2.dp.toPx(), cap = StrokeCap.Round)
        listOf(0.9f, 0.65f, 0.4f).forEachIndexed { i, r ->
            val p = ((progress - i * 0.15f) / 0.55f).coerceIn(0f, 1f)
            drawArc(color, 200f, 200f * p, false, style = s,
                topLeft = center - Offset(size.width * r / 2, size.height * r / 2),
                size = Size(size.width * r, size.height * r))
        }
    }
}
