Checksanimated

Spring check

A checkbox that springs with a bouncy scale and a ripple ring when ticked.

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 SpringCheckbox(checked: Boolean, onCheckedChange: (Boolean) -> Unit) {
    val scale by animateFloatAsState(
        targetValue = if (checked) 1f else 0.85f,
        animationSpec = spring(Spring.DampingRatioMediumBouncy, Spring.StiffnessMedium),
        label = "spring",
    )
    Checkbox(
        checked = checked,
        onCheckedChange = onCheckedChange,
        modifier = Modifier.scale(scale),
        colors = CheckboxDefaults.colors(checkedColor = MaterialTheme.colorScheme.primary),
    )
}
