Shimmer card

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

val t = rememberInfiniteTransition(label = "shimmer")
val x by t.animateFloat(
    initialValue = -400f,
    targetValue = 400f,
    animationSpec = infiniteRepeatable(tween(1600, easing = LinearEasing)),
    label = "x",
)
val base = MaterialTheme.colorScheme.surfaceVariant
val highlight = MaterialTheme.colorScheme.surface
val brush = Brush.linearGradient(
    colors = listOf(base, highlight, base),
    start = Offset(x, 0f),
    end = Offset(x + 200f, 0f),
)
Column(
    modifier = Modifier.width(176.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
) {
    Box(Modifier.fillMaxWidth().height(64.dp).clip(RoundedCornerShape(8.dp)).background(brush))
    Box(Modifier.fillMaxWidth(0.75f).height(12.dp).clip(RoundedCornerShape(4.dp)).background(brush))
}
