How to create Inherited classes in flutter with freezed?

[Zambeel-Ltd]

I am creating two classes in flutter with freezed this is my code

@freezed
abstract class Vehicle with _$Vehicle {
  const factory Vehicle({required String brand}) = _Vehicle;
}

@freezed
abstract class Car extends Vehicle with _$Car {
  const factory Car({required String brand, required int doors}) = _Car;
}

But I am getting error on _$Car saying

'$Car.copyWith' ('$CarCopyWith Function()') isn't a valid override of '$Vehicle.copyWith' ('$VehicleCopyWith Function()')

am I doing something wrong. is there any other way to implement Inheritance with freezed?

try:

@freezed
abstract class Vehicle with _$Vehicle {
  const Vehicle._();
  const factory Vehicle({required String brand}) = _Vehicle;
}

@freezed
abstract class Car extends Vehicle with _$Car {
  const Car._(): super._();
  const factory Car({required String brand, required int doors}) = _Car;
}

There's no constructor in your Vehicle class that can be subclassed. So we need to add one

@rrousselGit still getting same error

'_$Car.copyWith' ('$CarCopyWith<Car> Function()') isn't a valid override of '_$Vehicle.copyWith' ('$VehicleCopyWith<Vehicle> Function()').
