How can I use redux persist for only one reducer not for navigation reducer in my react native application?

问题

I am using Redux persist to persist my store for reducers. My application has two reducers Navigation and User Reducer.I want to persist only user state but I have to persist both states according to this syntax of redux persist.

          import {persistStore, autoRehydrate} from 'redux-persist'
          const store = createStore(reducer, undefined, autoRehydrate())
          persistStore(store)

the reducer that I have passed in the create store is the object of combine reducers.

Problem: The problem I am getting through this is when I exit my app, as the navigation state is also persist now, my app opens the same page from which I exited my app.

I am using navigation experimental with redux in my app and want to persist only user state.

redux-persist v5

Set the blacklist/whitelist in the PersistConfig, and use it in persistCombineReducers (the 1st param):

const persistConfig = {
  key: 'root',
  blacklist: ['navigation'],
  storage,
}

const reducer = persistCombineReducers(persistConfig , reducers)

redux-persist v4

persistStore can have an optional config object as the 2nd parameter. In the config object, you can define a black list of reducers to ignore, or a white list of reducers to include (and ignore the rest). Both accept an array of reducers' key names.

You can blacklist the navigation (or whatever yours is called) reducer:

persistStore(store, { blacklist: ['navigation'] })
