The method 'filter' isn't defined for the type 'IsarCollection'

[roshanproductions]

Steps to Reproduce

• Remove the previous isar and isar_flutter_libs versions.
• Run the following command
• flutter pub add isar:^4.0.3 isar_flutter_libs:^4.0.3 --hosted-url=https://pub.isar-community.dev
• added named schemas property to isar open object
• Run flutter pub run build_runner build

Build runner ran successfully, but I get the following error on queries:

The method 'filter' isn't defined for the type 'IsarCollection' Try correcting the name to the name of an existing method, or defining a method named 'filter'.

    final downloaderTaskCollection = _isar.downloaderTaskCollections  \\ works upto this line, but following lines produces error
        .filter()
        .mediaIdEqualTo(mediaId)
        .findFirstSync();

Details

• Dart version: [3.4.3]
• Flutter version: [3.22.2]
• Isar version: [4.0.3]

can you post your collection class?

[roshanproductions]

Here you go:

import 'package:isar/isar.dart';

part 'downloader_task_collection.g.dart';

@collection
class DownloaderTaskCollection {

  @id
  late int mediaId;

  String? tag;

  String? url;

  String? status;

  String? type;

  String? filename;

  double? progress;

  String? uriData;
}

For some reason, helper methods are not being generated, e.g mediaIdEqualTo() etc..

Hi, is this resolved ? I also have an error like this today

[vicenterusso]

Try this:

 final downloaderTaskCollection = _isar.downloaderTaskCollections
        .where()
        .mediaIdEqualTo(mediaId)
        .findFirst();

• there is no filter() and no findFirstSync() in v4, because it's the default

[roshanproductions]

_isar. downloaderTaskCollections
        .where()
        .optional(
          taskId != null,
          (q) => q.idNotEqualTo(taskId!), // this line is not working q.idNotEqualTo
        )

The error is: The method 'idNotEqualTo' isn't defined for the type 'QueryBuilder'
