updateLayerBlock

Function

Common

fun LayoutModifierNode.updateLayerBlock(layerBlock: (GraphicsLayerScope.() -> Unit)?)

Updates the layer block of the LayoutModifierNode. This will mark the layer as invalidated and schedule a refresh of the layer.

Updating the layer lambda using this method is cheaper than invalidating placement and placing the layout with a new layer block. This API is expected to be used alongside Placeable.placeAt with a layerBlock parameter passed. This will override/update the layerBlock passed in that API. Whichever one was called last should "win".

Parameters


layerBlock	the snapshot-observed lambda used to set properties on the layer. if `null`, is provided it will remove the layer.
