overlayEntries property Null safety
override
The overlay entries of this route.
These are typically populated by install. The Navigator is in charge of adding them to and removing them from the Overlay.
There must be at least one entry in this list after install has been invoked.
The Navigator will take care of keeping the entries together if the route is moved in the history.
Implementation
@override
List<OverlayEntry> get overlayEntries => _overlayEntries;
