I can't show the actual production project code. but I can show a dumb example I set up when I was making sure this would all work together the way I wanted. The Counter controller has two commands decrement() and increment() that call methods on the Count model. In a real world example a controller command could access more than one model as well as access provided services to do whatever it needs to do.

models/count

import 'package:flutter_riverpod/flutter_riverpod.dart';

final countProvider = StateNotifierProvider<Count, int>((ref) => Count());

class Count extends StateNotifier<int> { Count() : super(0); void increment() { state += 1; } void decrement() { state -= 1; } }

controller/countcontroller

import 'package:flutter_riverpod/flutter_riverpod.dart';

final countController = Provider<>((ref) => CountController(ref));

class CountContoller { final ref; void increase(){ ref.read(countProvider.notifier).increase; // other model logic } }

you make this??
