No MonitoringResult updates on iOS when beacon is not in range

[ksheremet]

_streamMonitoring = flutterBeacon.monitoring(regions).listen((MonitoringResult result) {
  // result contains a region, event type and event state
});

flutter_beacon: ^0.4.0

The app is in the foreground.

Android works well.

Hi @ksheremet

Which iOS device and version do you use as tester device?

@alann-maulana any updates yet?

Same is happening to me:

iOS 14 Iphone 11 Pro

Update: it's working now perfectly on iOS 14.7.1 :)

It was just my fault. Monitoring is fast and detects directly outside and inside. Good job @alann-maulana 👍🏼

Here's my version @ksheremet :

  final regions = <Region>[];
  final monitoringResults = <MonitoringResult>[];
  StreamSubscription<MonitoringResult>? _streamRanging;

  [...]

  void initBeaconRanger() async {
    regions.addAll([
      Region(identifier: 'Feasycom', proximityUUID: 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'),
    ]);
    _streamRanging = flutterBeacon
        .monitoring(regions)
        .asBroadcastStream()
        .listen((MonitoringResult result) {
      debugPrint(result.region.toString());
      debugPrint(result.monitoringState.toString());
      if (!monitoringResults.any((mon) => mon.region == result.region) &&
          result.monitoringState == MonitoringState.inside) {
        monitoringResults.add(result);
      } else {
        monitoringResults.removeWhere((m) => m.region == result.region);
      }
      setState(() {});
    });
    setState(() {});
  }
