Я пытаюсь сгенерировать файл router.gr.dart, используя пакет auto_route во flutter. В моем классе есть 3 именованных конструктора:

 ProfilePage.a({  Key? key,  this.profileType = UserType.a,  required this.a,  required this.userProfileId,  }) : super(key: key);   ProfilePage.b({  Key? key,  this.profileType = UserType.b,  required this.b,  required this.userProfileId,  }) : super(key: key);   ProfilePage.c({  Key? key,  this.profileType = UserType.c,  required this.c,  required this.userProfileId,  }) : super(key: key);   

Теперь, когда я пытаюсь сгенерировать файл router.gr.dart, он выдает ошибку:

 [INFO] Generating build script... [INFO] Generating build script completed, took 406ms  [INFO] Initializing inputs [INFO] Reading cached asset graph...

Генерация отлично работает для классов только с конструктором по умолчанию. Как мне решить эту проблему?
