SetList option gives me an error when writing a list of maps.

[delay]

Thanks for this great package! I am having one problem. I am getting an error when using setList to write a list of maps.

When I try and write to firestore and update a document with the setList option it gives me an error.

Unsupported operation: Value of type minified:b1 is not supported by Firestore.

I have a model that has a list of activities (a log of what the property has done)

class Property {
  String id;
  String owner;
  String email;
  List<Invoice> invoices;
  List<LogModel> activity;

  Property(
      {this.id,
      this.owner,
      this.email,
      this.activity});

  factory Property.fromMap(Map data) {
    return Property(
      id: data['id'],
      owner: data['owner'] ?? '',
      email: data['email'] ?? '',
      activity: (data['activity'] as List ?? [])
          .map((v) => LogModel.fromMap(v))
          .toList(),
    );
  }

  Map<String, dynamic> toJson() => {
        "id": id,
        "owner": owner,
        "email": email,
        "activity": List<dynamic>.from(activity.map((x) => x.toJson())),
      };
}

class LogModel {
  String id;
  String user;
  String message;
  int date;

  LogModel({this.id, this.user, this.message, this.date});

  LogModel.fromMap(Map data) {
    id = data['id'];
    user = data['user'] ?? '';
    message = data['message'] ?? '';
    date = data['date'];
  }

  Map<String, dynamic> toJson() => {
        "id": id,
        "user": user,
        "message": message,
        "date": date,
      };
}

 UpdateData propertyData = UpdateData();
  propertyData.setString("email", property.email);
  propertyData.setList("activity", property.activity);

  final ref = app.firestore().document('/properties/${property.id}');

  await ref.updateData(propertyData);

Thanks so much for any advice on how to handle this situation when it is a list of Maps.
