CircleAnnotation not visible from zoom 6 to 13 (including) on iOS

Nobody has claimed this yet.

**Edit 20.10.2025**
Issue can be reproduced on iOS Simulators with iOS 15.4 / 17.2 / 17.5 / tbc
Issue can NOT be reproduced on physical devices with iOS 15.6.1 / 18.6.2 / tbc
Hence priority of this issue is minor.
Feel free to close the issue if you don't want to address it.

**Environment**
Flutter (Channel stable, 3.29.3, on macOS 14.6.1 23G93 darwin-x64, locale de-DE)
Xcode - develop for iOS and macOS (Xcode 15.4)
VS Code (version 1.104.0)
mapbox_maps_flutter: ^2.11.0

**Pods**
- mapbox_maps_flutter (2.11.0):
- Flutter
- MapboxMaps (= 11.15.0)
- Turf (= 4.0.0)
- MapboxCommon (24.15.0):
- Turf (= 4.0.0)
- MapboxCoreMaps (11.15.0):
- MapboxCommon (= 24.15.0)
- MapboxMaps (11.15.0):
- MapboxCommon (= 24.15.0)
- MapboxCoreMaps (= 11.15.0)
- Turf (= 4.0.0)
- Turf (4.0.0)

**Steps to reproduce**
Run below code and increase/decrease the zoom between 1-21
Behaviour stays the same independant from the position. I tried with San Vito Lo Capo, Sicily and Apple HQ.

**Expected bahaviour**
CircleAnnotation should be visible in any zoom

**Actual behaviour**
CircleAnnotation vanishes from zoom 6 (including) to zoom 13 (including).

Did I miss sth in the docs or code?

```dart
import 'package:flutter/material.dart';
import 'package:mapbox_maps_flutter/mapbox_maps_flutter.dart';

void main() {
WidgetsFlutterBinding.ensureInitialized();

MapboxOptions.setAccessToken(
"YOUR-ACCESS-TOKEN",
);

runApp(const MyApp());
}

class MyApp extends StatelessWidget {
const MyApp({super.key});

// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(title: 'MapBox Test', home: const MyHomePage(title: 'MapBox Test'));
}
}

class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});

final String title;

@override
State createState() => _MyHomePageState();
}

class _MyHomePageState extends State {
MapboxMap? controller;
CircleAnnotationManager? circleAnnotationManager;
double currentZoom = 14;

@override
Widget build(BuildContext context) {
var pos = Position(-122.0308, 37.3318); // Apple HQ (Cupertino, CA)
// var pos = Position(12.7357, 38.1706); // San Vito lo Capo
return Scaffold(
appBar: AppBar(title: Text(widget.title)),

},
icon: Icon(Icons.zoom_out),

Text("Current zoom: $currentZoom"),

Expanded(
child: MapWidget(
onMapCreated: (mapController) async {
controller = mapController;
circleAnnotationManager = await controller!.annotations.createCircleAnnotationManager(id: "circles1");
// await controller!.style.setStyleLayerProperty("circles1", "minzoom", 1.0);
// await controller!.style.setStyleLayerProperty("circles1", "maxzoom", 21.0);

circleAnnotationManager!.create(
CircleAnnotationOptions(
geometry: Point(coordinates: pos),
circleColor: Colors.blue.toARGB32(),
circleStrokeColor: Colors.white.toARGB32(),
circleStrokeWidth: 1,
circleRadius: 10,
),
);
},
cameraOptions: CameraOptions(zoom: 14, center: Point(coordinates: pos)),
),
),
],
),
);
}
}

Start with the provided Flutter sample and reproduce the CircleAnnotation behavior on the listed iOS Simulators, comparing it with physical devices. Inspect the annotation manager and the commented style-layer minzoom/maxzoom calls mentioned in the sample. Done means the circle remains visible at zoom levels 6 through 13 without changing behavior at other zoom levels.
