Lock

A padlock whose shackle lifts and re-seats as it locks and unlocks, with a subtle bounce.

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 LockToggle(locked: Boolean, onToggle: () -> Unit) {
    val lift by animateFloatAsState(if (locked) 0f else -4f, spring(stiffness = 400f), label = "lift")
    val rot by animateFloatAsState(if (locked) 0f else -18f, spring(stiffness = 400f), label = "rot")
    val color = MaterialTheme.colorScheme.primary
    Box(Modifier.size(40.dp).clickable(onClick = onToggle), contentAlignment = Alignment.Center) {
        Icon(Icons.Filled.Lock, null, tint = color, modifier = Modifier.size(28.dp))
        // shackle redrawn on top so it can lift independently
        Canvas(Modifier.size(28.dp)) {
            translate(top = lift.dp.toPx()) {
                rotate(rot, pivot = Offset(size.width * 0.32f, size.height * 0.42f)) {
                    drawArc(color, 180f, 180f, false,
                        topLeft = Offset(size.width * 0.32f, size.height * 0.18f),
                        size = Size(size.width * 0.36f, size.height * 0.36f),
                        style = Stroke(2.5.dp.toPx(), cap = StrokeCap.Round))
                }
            }
        }
    }
