Upload

An upward arrow above a determinate bar filling to show upload progress.

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 = "upload")
val progress by t.animateFloat(
    initialValue = 0f,
    targetValue = 1f,
    animationSpec = infiniteRepeatable(tween(1800, easing = LinearEasing)),
    label = "progress",
)
val primary = MaterialTheme.colorScheme.primary
Column(
    horizontalAlignment = Alignment.CenterHorizontally,
    verticalArrangement = Arrangement.spacedBy(8.dp),
) {
    Icon(
        Icons.Filled.CloudUpload,
        contentDescription = "Uploading",
        tint = primary,
        modifier = Modifier.size(24.dp),
    )
    LinearProgressIndicator(
        progress = { progress },
        modifier = Modifier.width(120.dp),
        color = primary,
        trackColor = MaterialTheme.colorScheme.surfaceVariant,
    )
}
