region.didEnter is only true if the position changes from inside to outside the region. So the variable should be called didExit. However, I need the scenario where the user enters the region. Could it be that there is a bug in the Flutter SDK and didEnter and didExit have been accidentally swapped?

```auto
...
final watchRegionStream = geofencingService.getWatchRegionStream();
    watchRegionStream?.listen((region) {
      if (region.didEnter) {
        final waypoint = waypoints.firstWhereOrNull((w) => w.id == region.identifier);
        if (waypoint != null) {
          geofencingRepo.addVisitedWaypoint(waypoint);
        }
      }
      debugPrint('region: ${region.eventName}');
    });
...

```
