Underline Grow

A text button with an underline that sweeps in from the left.

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

Box {
    TextButton(
        onClick = {},
        contentPadding = PaddingValues(0.dp),
    ) { Text("Read story") }
    // Animate width 0 -> full on hover/press
    Box(
        Modifier
            .align(Alignment.BottomStart)
            .height(2.dp)
            .fillMaxWidth()
            .background(MaterialTheme.colorScheme.primary),
    )
}
