Usage

Get a dependency

Step 1. Add the MavenCentral repository to your build file. Add it in your root build.gradle.kts at the end of repositories:

allprojects {
    repositories {
        ...
        mavenCentral()
    }
}

Or in settings.gradle.kts:

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

Step 2. Add the dependency. Check latest version on the releases page.

dependencies {
    implementation("io.github.oleksandrbalan:tagcloud:$version")
}

Use in Composable

The TagCloud has 2 mandatory arguments:

• state - The state of the TagCloud, used to observe and change it's rotation.
• content - The content lambda to register items to be shown in the TagCloud.

Inside content lambda use item or items method to register items in the TagCloud. Each method has own content lambda to specify how item is displayed. Inside item scope you could access item's coordinates to adjust appearance based on where item is currently in the tag cloud. Or you may use .tagCloudItemFade() and / or .tagCloudItemScaleDown() modifiers to use out-of-box behavior.

val labels = List(32) { "Item #$it" }

TagCloud(
    state = rememberTagCloudState(),
    modifier = Modifier.padding(64.dp)
) {
    items(labels) {
        Text(
            text = it,
            modifier = Modifier
                .tagCloudItemFade()
                .tagCloudItemScaleDown()
        )
    }
}

See Demo application and examples for more usage examples.
