Gradient bar

A track filled with a gradient that scrolls endlessly sideways.

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 = "gradbar")
val shift by t.animateFloat(
    initialValue = 0f,
    targetValue = 200f,
    animationSpec = infiniteRepeatable(tween(1800, easing = LinearEasing)),
    label = "shift",
)
val c1 = MaterialTheme.colorScheme.primary
val c2 = MaterialTheme.colorScheme.tertiary
Box(
    Modifier
        .width(160.dp)
        .height(6.dp)
        .clip(RoundedCornerShape(50))
        .background(
            Brush.linearGradient(
                colors = listOf(c1, c2, c1),
                start = Offset(shift, 0f),
                end = Offset(shift + 200f, 0f),
                tileMode = TileMode.Mirror,
            ),
        ),
)
