Download

This library still in alpha stage. Implementations might change in the future.

Requirements to use:

  • Kotlin version 1.8.20 or above.
  • Compose version 1.4.0.
  • Minimum API version 21 (For Android).

Add mavenCentral to your dependency management.

dependencyResolutionManagement {
    repositories {
        // ...
        mavenCentral()
    }
}

Then, add the speedometer dependencies according to your project:

Compose Multiplatform Project

Go to build.gradle.kts file in the shared module. In commonMain dependencies:

sourceSets {
    val commonMain by getting {
        dependencies {
            // Add Speedometer library
            implementation("com.github.anastr:speedometer:1.0.0-ALPHA01")
        }
    }
    // ...
}

Native Android Project

If you want to use the library only in a native Android project. Add this line to build.gradle.kts app module level:

dependencies {
    implementation("com.github.anastr:speedometer-android:1.0.0-ALPHA01")
}

Simple Usage

Currently, this library only supports SpeedView. To use it, just call SpeedView composable like so:

SpeedView(
    modifier = Modifier.size(250.dp),
    speed = 50f,
)

By default, this library doesn’t implement any animation. To make the indicator move smoothly, use compose animation :

var speed by remember { mutableStateOf(0f) }
val currentSpeed by animateFloatAsState(
    targetValue = speed,
    animationSpec = tween(durationMillis = 2000, easing = FastOutSlowInEasing)
)
Column(
    modifier = Modifier
        .fillMaxWidth()
        .padding(12.dp),
    horizontalAlignment = Alignment.CenterHorizontally,
) {
    SpeedView(
        modifier = Modifier.size(250.dp),
        speed = currentSpeed,
    )
    Button(
        onClick = {
            // Change speed to start the animation
            speed = Random.nextFloat() * 100
        },
    ) {
        Text("Random speed")
    }
}
