Freezed Class/ Model not being updated by copyWith

[aldrin-goyazi]

I'm new to freezed and riverpod. I tried creating a custom Class to handle the state. But the watchers always show the initState which is null, Printed the state after the copywith , and it shows the correct value. I don't know why the state doesn't update on the watchers.

My notifier

@riverpod
class OnboardingNotif extends _$OnboardingNotif {
  @override
  OnboardingModel build() {
    OnboardingModel initState = OnboardingModel();
    return initState;
  }

  void setEmail(String? newValue) {
    print("email $newValue");
    print("state email ${state.email}");
    state = state.copyWith(email: newValue);
  }

  void setOtp(String newValue) {
    print("otp $newValue");
    state = state.copyWith(otp: newValue);
    print(state.toJson().toString());
  }
}

My Freezed Class Model

@freezed
class OnboardingModel with _$OnboardingModel {
  const factory OnboardingModel({
    String? email,
    String? otp,
  }) = _OnboardingModel;

  factory OnboardingModel.fromJson(Map<String, dynamic> json) =>
      _$OnboardingModelFromJson(json);
}
