Lazy Tree List for Jetpack Compose

Getting Started

1. Download

Add a dependency on the library to your Android project (Desktop not supported for now)

dependencies {
    implementation("io.github.mr0xf00:lazytreelist:0.1.0")
}

2. Add LazyTreeList Composable to your composition

LazyTreeList(
    modifier = Modifier.weight(1f).fillMaxWidth(),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    contentPadding = PaddingValues(8.dp),
    //content
)

3. Add content :

You can either use the experimental DSL :

LazyTreeList(
    //...
    content = items(
        count = 10,
        subItems = { itemIndex ->
            if(itemIndex < 5) items(1) { subItemIndex -> Text("SubItem $subItemIndex") }
        }
    ) { itemIndex ->
        Text("ContainerItem $i")
    }
)

Or provide your own implementation of ItemTree

LazyTreeList(
    //...
    items = myData.asItemTree()
)

See AppUi.kt for an example implementation
