Constructors

TransformItemState

constructor(key: Any = Unit, blockCompose: @Composable (Any) -> Unit = {}, scope: CoroutineScope, blockPosition: Offset = Offset.Zero, blockSize: IntSize = IntSize.Zero, intrinsicSize: Size? = null, checkInBound: TransformItemState.() -> Boolean? = null)

Properties

var blockCompose: @Composable (Any) -> Unit

实际TransformItem中显示的内容

var blockPosition: Offset

TransformItem的绝对位置

var blockSize: IntSize

TransformItem的大小

var checkInBound: TransformItemState.() -> Boolean?

判断当前TransformItem是否在显示范围内的方法

var intrinsicSize: Size?

传入blockCompose的固有大小

var key: Any

当前TransformItem的唯一标识

var scope: CoroutineScope

协程作用域

Functions

fun addItem(key: Any? = null, itemMap: ItemStateMap)

添加item到map上

fun checkIfInBound(itemMap: ItemStateMap, checkInBound: () -> Boolean)

判断item是否在所需范围内，返回true，则添加该item到map，返回false则移除

fun removeItem(key: Any? = null, itemMap: ItemStateMap)

从map上移除item
