Freezed: Does this is a valid usage of Freezed?

[pedromassango]

I have the following class:

@freezed
abstract class Transaction with _$Transaction implements Entity {
  const factory Transaction({
    @required UniqueId id,
    @required Money amount,
    @required PhoneNumber phoneNumber,
  }) = _Transaction;

  String getMaskedPhoneNumber() {
    return RegExpUtil.replaceAndKeepLastThreeDigits(phoneNumber.getOrElse(''));
  }
}

Is this a valid usage of Freezed? I'm receiving the following error (at compile time):

Compiler message:
lib/src/domain/transactions/entities/transaction.freezed.dart:35:7: Error: The non-abstract class '_$_Transaction' is missing implementations for these members:
 - Transaction.getMaskedPhoneNumber
Try to either
 - provide an implementation,
 - inherit an implementation from a superclass or mixin,
 - mark the class as abstract, or
 - provide a 'noSuchMethod' implementation.

Currently fixed it by adding the method in a extension of my class:

extension TransactionExt on Transaction {
  String getMaskedPhoneNumber() {
    return RegExpUtil.replaceAndKeepLastThreeDigits(phoneNumber.getOrElse(''));
  }
}

The problem and solution is explained in the README here:
https://github.com/rrousselGit/freezed#custom-getters-and-methods

If there is something that you do not understand, feel free to let me know,
so that I can update the readme :)

I've updated as follow:

part 'transaction.freezed.dart';

@freezed
abstract class Transaction implements _$Transaction {
  const factory Transaction({
    @required UniqueId id,
    @required Money amount,
    @required PhoneNumber phoneNumber,
  }) = _Transaction;

  String getMaskedPhoneNumber() {
    return RegExpUtil.replaceAndKeepLastThreeDigits(phoneNumber.getOrElse(''));
  }
}

but I keep receiving the error

[rrousselGit]

You are missing on the Transaction._(); constructor

Sorry, I copied the wrong code, please take a look at the image

[rrousselGit]

Have you re-generated your source code?

You should have class _$_Transaction extends _Transaction instead
