final
drawInSingleWorld bool
Whether polylines should only be drawn/projected onto a single world instead of potentially being drawn onto adjacent worlds (based on the shortest distance)
final
hashCode int

no setterinherited
hitNotifier LayerHitNotifier<R>?
A notifier to be notified when a hit test occurs on the layer
final
key Key?
Controls how one widget replaces another widget in the tree.
