Properties

anchorX	`val anchorX: Double?` Transform anchor point X, absent if no transform specified
anchorY	`val anchorY: Double?` Transform anchor point Y, absent if no transform specified
anchorZ	`val anchorZ: Double?` Transform anchor point Z, absent if no transform specified
backendNodeId	`val backendNodeId: BackendNodeId?` The backend id for the node associated with this layer.
drawsContent	`val drawsContent: Boolean` Indicates whether this layer hosts any content, rather than being used for transform/scrolling purposes only.
height	`val height: Double` Layer height.
invisible	`val invisible: Boolean?` Set if layer is not visible.
layerId	`val layerId: LayerId` The unique id for this layer.
offsetX	`val offsetX: Double` Offset from parent layer, X coordinate.
offsetY	`val offsetY: Double` Offset from parent layer, Y coordinate.
paintCount	`val paintCount: Int` Indicates how many time this layer has painted.
parentLayerId	`val parentLayerId: LayerId?` The id of parent (not present for root).
scrollRects	`val scrollRects: List<ScrollRect>?` Rectangles scrolling on main thread only.
stickyPositionConstraint	`val stickyPositionConstraint: StickyPositionConstraint?` Sticky position constraint information
transform	`val transform: List<Double>?` Transformation matrix for layer, default is identity matrix
width	`val width: Double` Layer width.
