[BUG] allOf $ref not used as type

[gem85247]

Describe the bug
When generating dart files the generator does not account for the provided $ref type in the allOf when using an array type (swagger snippet below):

...

"MultipleOrganizationResponse": {
        "type": "object",
        "properties": {
          "data": {
            "type": "array",
            "items": {
              "nullable": false,
              "allOf": [
                {
                  "$ref": "#\/components\/schemas\/Organization"
                }
              ],
              "description": "entity|class:OrganizationPlatformApiEntity"
            },
            "required": [
              "items"
            ]
          },

...

this results into the following dart code:

@JsonSerializable(explicitToJson: true)
class MultipleOrganizationResponse {
  const MultipleOrganizationResponse({
    this.data,
    this.meta,
  });

  factory MultipleOrganizationResponse.fromJson(Map<String, dynamic> json) =>
      _$MultipleOrganizationResponseFromJson(json);

  static const toJsonFactory = _$MultipleOrganizationResponseToJson;
  Map<String, dynamic> toJson() => _$MultipleOrganizationResponseToJson(this);

  @JsonKey(name: 'data', defaultValue: <Object>[])
  final List<Object>? data;
  @JsonKey(name: 'meta')
  final MultipleOrganizationResponse$Meta? meta;
  static const fromJsonFactory = _$MultipleOrganizationResponseFromJson;

  @override
  String toString() => jsonEncode(this);
}

Notice final List<Object>? data; should in fact be final List<Organization>? data;
My assumption is that something goes wrong because of the type: "array". Because if we look at the swagger snippet below:

...

"SingleOrganizationResponse": {
        "type": "object",
        "properties": {
          "data": {
            "nullable": false,
            "allOf": [
              {
                "$ref": "#\/components\/schemas\/Organization"
              }
            ],
            "description": "entity|class:OrganizationPlatformApiEntity"
          },
          "meta": {
            "type": "object",
            "properties": {
              "count": {
                "nullable": false,
                "type": "integer",
                "example": 123,
                "description": "int"
              }
            },
            "required": [
              "count"
            ]
          }
        },
        "required": [
          "data"
        ]
      },
...

it reproduces a an expected (& correct) dart file:

@JsonSerializable(explicitToJson: true)
class SingleOrganizationResponse {
  const SingleOrganizationResponse({
    required this.data,
    this.meta,
  });

  factory SingleOrganizationResponse.fromJson(Map<String, dynamic> json) =>
      _$SingleOrganizationResponseFromJson(json);

  static const toJsonFactory = _$SingleOrganizationResponseToJson;
  Map<String, dynamic> toJson() => _$SingleOrganizationResponseToJson(this);

  @JsonKey(name: 'data')
  final Organization data;
  @JsonKey(name: 'meta')
  final SingleOrganizationResponse$Meta? meta;
  static const fromJsonFactory = _$SingleOrganizationResponseFromJson;

  @override
  String toString() => jsonEncode(this);
}

As you can see, because the type is not array but object, it generates the correct type: final Organization data;.
So I presume something goes wrong when the type is array.

To Reproduce

using the folowing build.yaml:

targets:
  $default:
    sources:
      - lib/**
      - swagger/**
      - $package$
      - pubspec.yaml
    builders:
      swagger_dart_code_generator:
        options:
          input_folder: "swagger/"
          input_urls:
            - url: "https://api-dev.guestway.io/swagger/swagger-platform.json"
          output_folder: "lib/generated/"
          separate_models: true
          ignore_headers: true
          cut_from_model_names: apiPlatformV1
          override_equals_and_hashcode: false
          use_path_for_request_names: false

it will reproduce the issue explained above.

Expected behavior

final List<Object>? data; should in fact be final List<Organization>? data;

No additional context needed (I think). Happy to provide more if needed of course :)
