Possible crash in notification streams

[nielsenko]

Running the following loop long enough, will either hang the notifications, or in rare cases crash the app. At least on macOS 14.3 Sonoma, using realm 1.7, and dart 3.2.5.

import 'dart:isolate';

import 'package:realm_dart/realm.dart';

part 'stream_101.g.dart';

@RealmModel()
class _Stuff {
  late int value;
}

final realm = Realm(Configuration.local([Stuff.schema]));

Future<void> main(List<String> arguments) async {
  Isolate.run(() async {
    int i = 0;
    while (true) {
      realm.write(() {
        realm.add(Stuff(i++));
      });
      await Future.delayed(const Duration(milliseconds: 200));
    }
  });

  final results = realm.all<Stuff>();
  await for (final stuff in results.changes) {
    print(stuff.results.length);
  }
}
