Request to enhance the documentation

[dilipagheda]

Hello,
I am trying to use redux in my project and going through documentation. One thing I found bit confusing is to understand the method signatures and what each parameter do and how it is used.
I was wondering if it can be added in the documentation.
Thanks
Dilip

And I'm struggling to work out how to write a reducer that updates a part of a (immutable) state. For example, this is not enough just to update the filters part of the state:

class AppState {
  final List<Resto> restos;
  final Filters filters;

  AppState({@required this.restos, @required this.filters});

  factory AppState.setFilters(filters) => AppState(filters: filters);
