Changes in moor package

Moor package has been renamed to Drift. The reason for this is that, in some parts of the world, moor may be used as a derogatory term.Learn more about migration here.

After the above changes, you can now run flutter pub run build_runner build to generate the code. We might run into some issues. To fix it refer to the following:

  • test/features/notification/presentation/widgets/system_notification/notification_item_test Import

    import 'package:drift/drift.dart';

    Line 76 - Line 77

    notificationsModel.systemNotifications.first
      .copyWith(notificationType: NotificationType.info);

    should be changed to:

    notificationsModel.systemNotifications.first.copyWith(
      notificationType:
          const Value<NotificationType>(NotificationType.info));

    Line 92 - Line 93

    notificationsModel.systemNotifications.first
      .copyWith(notificationType: NotificationType.danger);

    should be changed to:

    notificationsModel.systemNotifications.first.copyWith(
      notificationType:
          const Value<NotificationType>(NotificationType.danger));
