Air Quality

42Good

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

@Composable
fun AirQualityCard() {
  val aqi = 42
  OutlinedCard(Modifier.fillMaxWidth()) {
    Column(Modifier.padding(20.dp)) {
      Text(
        "Air Quality",
        style = MaterialTheme.typography.titleMedium
      )
      Spacer(Modifier.height(12.dp))
      Row(verticalAlignment = Alignment.Bottom) {
        Text(
          "$aqi",
          style = MaterialTheme.typography.displaySmall,
          color = Color(0xFF34C759)
        )
        Spacer(Modifier.width(8.dp))
        Text(
          "Good",
          style = MaterialTheme.typography.titleMedium,
          color = Color(0xFF34C759)
        )
      }
      Spacer(Modifier.height(12.dp))
      Canvas(Modifier.fillMaxWidth().height(8.dp)) {
        drawRoundRect(
          Brush.horizontalGradient(
            listOf(
              Color(0xFF34C759), Color(0xFFFFCC00),
              Color(0xFFFF9500), Color(0xFFFF3B30)
            )
          ),
          cornerRadius = CornerRadius(8f, 8f)
        )
        val x = size.width * (aqi / 300f)
        drawCircle(Color.White, 7f, Offset(x, size.height / 2))
      }
    }
  }
