Failed to generate mixin on Store

[subzero911]

I have a repeating pagination code, so I moved it out from Store to mixin:

import 'package:mobx/mobx.dart';

import 'logger.dart' show log;

mixin PaginatedStoreMixin<T, R extends PaginatedResponse<T>> on Store {
  @observable
  ObservableList<T> models = ObservableList<T>();

  @observable
  ObservableFuture<R?> fetchFuture = ObservableFuture.value(null);

  @observable
  Object? _cursor;

  @observable
  Object? _previousCursor;

  @computed
  bool get hasReachedMax => _previousCursor == _cursor || _cursor == null;

  @computed
  bool get isLoading => fetchFuture.status == FutureStatus.pending;

  Future<R?> performFetch(Object? cursor);

  @action
  Future<List<T>?> fetch() async {
    fetchFuture = ObservableFuture(
      performFetch(_cursor).catchError((error, stackTrace) {
        log.e('Error while loading', error: error, stackTrace: stackTrace);
        throw error;
      }),
    );

    await fetchFuture;
    final resp = fetchFuture.value;

    if (resp != null && resp.data != null) {
      models.addAll(resp.data!);

      _previousCursor = _cursor;
      _cursor = resp.cursor;

      log.d('Elements loaded: ${resp.data!.length}');
      log.d('cursor: $_cursor');
    }

    return resp?.data;
  }

  @action
  void resetPagination() {
    _cursor = null;
    _previousCursor = null;
    models.clear();
  }
}

abstract class PaginatedResponse<T> {
  List<T>? get data;
  Object? get cursor;
}

Then I override performFetch with a concrete repository.

Everything seems to work fine, but no data from PaginatedStoreMixin is being generated:

mixin _$BotsPaymentsController on _BotsPaymentsControllerBase, Store {
  late final _$filtersModelAtom = Atom(

      value,
      super.exportCsvSettingsModel,
      () {
        super.exportCsvSettingsModel = value;
      },
    );
  }

  late final _$_BotsPaymentsControllerBaseActionController = ActionController(
    name: '_BotsPaymentsControllerBase',
    context: context,
  );

  @override
  void clearSearch() {
    final _$actionInfo = _$_BotsPaymentsControllerBaseActionController
        .startAction(name: '_BotsPaymentsControllerBase.clearSearch');
    try {
      return super.clearSearch();
    } finally {
      _$_BotsPaymentsControllerBaseActionController.endAction(_$actionInfo);
    }
  }

  @override
  void clearFilters() {
    final _$actionInfo = _$_BotsPaymentsControllerBaseActionController
        .startAction(name: '_BotsPaymentsControllerBase.clearFilters');
    try {
      return super.clearFilters();
    } finally {
      _$_BotsPaymentsControllerBaseActionController.endAction(_$actionInfo);
    }
  }

  @override
  String toString() {
    return '''
filtersModel: ${filtersModel},
exportCsvSettingsModel: ${exportCsvSettingsModel}
    ''';
  }
}
