[ODM] Get list of references

[ianmaciel]

I think this is related to @AirborneEagle question on #7475 (comment) but it wasn't understood.

Is there a way to create my models where I have a list of references in Firestore?

In Firestore I have:

Collection People:
- name (String)
- active (bool)

Collection Projects
- name (String)
- active (bool)
- people (Array of references -> each is a person)
- - '/people/xsiuhuhfs'

On my Dart code, I have my model:

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:json_annotation/json_annotation.dart';
import 'package:cloud_firestore_odm/cloud_firestore_odm.dart';

part 'project_model.g.dart';

@JsonSerializable(explicitToJson: true)
class Project {
  Project({
    required this.name,
    required this.active,
    required this.people,
  });
  String name;
  bool active;
  // Here is the problem, I don't have a List of person. I have a list of _JsonDocumentReference!
  List<Person> people;

  factory Project.fromJson(Map<String, Object?> json) =>
      _$ProjectFromJson(json);
  Map<String, Object?> toJson() => _$ProjectToJson(this);
}

@Collection<Project>('projects')
final ProjectCollectionReference projectsRef = ProjectCollectionReference();

Is there a way to convert this to reference?
