Focus glow

Field that lifts a soft neon glow around itself the moment it gains focus.

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

var focused by remember { mutableStateOf(false) }
val glow by animateDpAsState(
    if (focused) 16.dp else 0.dp, label = "glow",
)
OutlinedTextField(
    value = value,
    onValueChange = { value = it },
    placeholder = { Text("Focus me") },
    modifier = Modifier
        .onFocusChanged { focused = it.isFocused }
        .shadow(glow, MaterialTheme.shapes.medium, spotColor = Color(0xFF6366F1)),
    colors = OutlinedTextFieldDefaults.colors(
        focusedBorderColor = Color(0xFF6366F1),
    ),
)
