Target of Backlink does not exist for IsarLinks

[kanntim]

Steps to Reproduce

When I try to make a @Backlink using IsarLinks, I get the error "Target of Backlink does not exist".
Even the code from the official example gives the same error:

Code sample

@collection
class Teacher {
  Id id = Isar.autoIncrement;

  late String subject;

  @Backlink(to: 'teacher')
  final student = IsarLinks<Student>();
}

@collection
class Student {
  Id? id = Isar.autoIncrement;

  late String name;
  
}

The ERROR:

Target of Backlink does not exist
package:app/entity.dart:10:9
   ╷
10 │   final student = IsarLinks<Student>();
   │         ^^^^^^^
   ╵

Details

• Platform: Android 13, API Level 33, x86_64 Android Emulator on Linux.
• Flutter version: [3.19.5]

@kanntim
Student() no have IsarLinks,so no backlink.
You can

@collection
class Teacher {
  Id id = Isar.autoIncrement;

  late String subject;

  @Backlink(to: 'name')
  final student = IsarLinks<Student>();
}

@collection
class Student {
  Id? id = Isar.autoIncrement;

  final name=IsarLinks<Teacher>();
  
}
