Flutter Riverpod provider widget not rebuilding

This is my code:

class MealsNotifier extends Notifier<List<Meal>> {

@override
  List<Meal> build() {
    return userMeals;
  }
  updateList(List<Meal> meals) {
    state = List.from(meals);
  }
}

final mealsProvider = NotifierProvider<MealsNotifier, List<Meal>>(() {
  return MealsNotifier();
});

In Categories class I have:

final meals = ref.watch(mealsProvider);

In EditMeal class I have:

ref.read(mealsProvider.notifier).updateList(userMeals);

My app structure is Categories -> Meals -> MealDetails -> EditMeal

After I'm done editing the meal, I expect all these widgets to rebuild since Categories has the ref.watch method.

Edit:

Migrated to Notifier. Still the same issue.

Using the debugger, state is being updated, but nothing rebuilds.

Given the current details, there's no issue in the update mechanism itself.

Check that userMeals argument is updating before passing it.

If Meals is a List of widgets make sure their configuration (params) are enough for Flutter to differentiate between them, otherwise consider using a ValueKey for each one with a suitable value.
