Memory leak if map is not visible

It seems that if the map is in an IndexedStack and is not visible, then some kind of a condition is triggered that allows the memory usage to grow until no more memory can be allocated and the app crashes.

Over the course of 114s the app allocated 10GB of memory:

Not for the same run, but I assume the details are the same:

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  MapboxOptions.setAccessToken("<TOKEN HERE>");

  runApp(MaterialApp(home: MapSample()));
}

class MapSample extends StatefulWidget {
  @override
  State<MapSample> createState() => _MapSampleState();
}

class _MapSampleState extends State<MapSample> {
  final locationSettings = LocationComponentSettings(
    enabled: true,
    showAccuracyRing: true,
    pulsingEnabled: false,
    puckBearingEnabled: true,
    puckBearing: PuckBearing.HEADING
  );

  var lastLocation = Position(0, 0);

  Stream<Position>? location;

  @override
  initState() {
    super.initState();

    location = Stream.periodic(const Duration(seconds: 1), (_) {
      lastLocation = Position((lastLocation.lng + 1) % 180, (lastLocation.lat + 1) % 90);

      return lastLocation;
    });
  }

  @override
  Widget build(BuildContext context) => Scaffold(
    body: IndexedStack(index: 0, children: [
      Container(),
      StreamBuilder<Position>(stream: location, builder: (context, snapshot) {
        return MapWidget(
          key: ValueKey(lastLocation.toJson().toString()),
          cameraOptions: CameraOptions(center: Point(coordinates: snapshot.data ?? lastLocation), zoom: 4, pitch: 0.0),
          onMapCreated: (MapboxMap mapboxMap) async {
            await Future.wait([
              mapboxMap.scaleBar.updateSettings(ScaleBarSettings(enabled: false)),
              mapboxMap.gestures.updateSettings(GesturesSettings(rotateEnabled: false)),
              mapboxMap.attribution.updateSettings(AttributionSettings(clickable: false, iconColor: 1)),
              mapboxMap.location.updateSettings(locationSettings),
            ]);
          }
        );
      })
    ]));
}

Start by running the linked mbmemleak reproduction with the provided IndexedStack, StreamBuilder, and MapWidget setup, comparing memory use while the map is visible and hidden. Inspect the MapWidget lifecycle and location stream behavior during repeated updates; done means the hidden map no longer causes unbounded memory growth or an eventual allocation failure.
