Although you don't need the MainModel it might help if you wanted to add more models in the future? I think the following should work. Try and change the class for mixin and extends to on in the models that aren't Main Model.
Main Model
import 'package:scoped_model/scoped_model.dart';
import './posts.dart';
import './user.dart';
class MainModel extends Model with UserModel, PostsModel {}
Posts Model
import 'package:scoped_model/scoped_model.dart';
import '../models/post.dart';
mixin PostsModel on Model {
List<Post> _posts = [];
List<Post> get posts {
return List.from(_posts);
}
void addPost(Post product) {
_posts.add(product);
}
void updatePost(int index, Post product) {
_posts[index] = product;
}
void deletePost(int index) {
_posts.removeAt(index);
}
}
User Model
import 'package:scoped_model/scoped_model.dart';
import '../models/user.dart';
mixin UserModel on Model {
User _authenticatedUser;
void login(String email, String password) {
_authenticatedUser = User(id: 'xxxxx', email: email, password: password);
}
}
from scoped_model.

I don't get why you need the MainModel at all. Isn't it enough to nest the models in each other?
new ScopedModel<UserModel>(
model: new UserModel(),
child: new ScopedModel<PostsModel>(
model: new PostsModel(),
child: myApp,
),
);
from scoped_model.

- mixin ProductModel on Model {}
- mixin UserModel on Model {}
- class MainModel extends Model with UserModel, ProductModel {}
Try out this. It worked for me.

Can you post some code? You can't mixin a Model because to mixin a class, it has to extend Object.

Thanks for the reply @passsy . Appreciate it!
So I guess I try to mixin 2 models to each other which is not allowed right? Any idea what I have todo different? Just call Model on the main model and keep the other 2 as class only?
Please keep in mind I changed Products to Posts, just a renaming.
Main Model
import 'package:scoped_model/scoped_model.dart';
import './posts.dart';
import './user.dart';
class MainModel extends Model with UserModel, PostsModel {}
Posts Model
import 'package:scoped_model/scoped_model.dart';
import '../models/post.dart';
class PostsModel extends Model {
List<Post> _posts = [];
List<Post> get posts {
return List.from(_posts);
}
void addPost(Post product) {
_posts.add(product);
}
void updatePost(int index, Post product) {
_posts[index] = product;
}
void deletePost(int index) {
_posts.removeAt(index);
}
}
User Model
import 'package:scoped_model/scoped_model.dart';
import '../models/user.dart';
class UserModel extends Model {
User _authenticatedUser;
void login(String email, String password) {
_authenticatedUser = User(id: 'xxxxx', email: email, password: password);
}
}
from scoped_model.
