[BUG] [dart-dio-next] Custom Date type has no replace method

[MihaMarkic]

Description

In yaml definition I have a class with a property like this:

absentFrom:
        $ref: '#/definitions/Date'

and below is Date definition as

Date:
    type: object
    required:
      - year
      - month
      - day
    properties:
      year:
        type: integer
        format: int32
      month:
        type: integer
        format: int32
      day:
        type: integer
        format: int32

Generator creates code that relies on autogenerated Date type's replace method which does not exist.

case r'absentFrom':
          final valueDes = serializers.deserialize(value,
              specifiedType: const FullType(Date)) as Date;
          result.absentFrom.replace(valueDes);
          break;

The problem is that there is no replace method on dart's Date type, at least so it seems.

Generation Details

˙... -g dart-dio-next -c open-generator-config.yaml --enable-post-process-file
dart-dio yields same result

Steps to reproduce

Generate dart-dio-next code from

Suggest a fix

Deserialization should create a new Date instance instead of using replace method.

Can you try using import mappings according to #10522 please.
We are creating an own Date class with dart-dio-next these two are probably conflict.
You should be able to fix that with mappings.

@kuhnroyal Will try and feedback here, thanks

May I have "open-generator-config.yaml" this file?
I think I also need one more yaml file.

Thank you. @MihaMarkic

[kuhnroyal]

@MihaMarkic Can you tell us if you solved this via mappings?

[MihaMarkic]

@kuhnroyal For the time being I just manually updated generated sources and then I postponed the project. So I didn't do much in this direction yet.
