_this.store.getState is not a function about redux-persist

1. the return value from persistStore is persistor not store. So your code should look more like:

import createStore from './redux/configureStore'
import {persistStore} from 'redux-persist'
const store = createStore()
const persistor =  persistStore(store, {storage: AsyncStorage})

1. You can pass in a whitelist of reducer keys like so:
   const persistor = persistStore(store, {storage: AsyncStorage, whitelist: ['reducerA', 'reducerB']})

Great! Would I pass down the store as well as the persistor object to my provider? So basically the persistor object would only persist the keys you put in the whitelist array? @rt2zz

 <Provider store={store} persistor={persistor}>

One more thing, Is it possible to pass a persisted store down to my child the <Provider component?

The following store={store} is just parsing down my default reducer, instead of the persisted one?

<Provider persistor={persistor} store={store}>
    <Routes store={store} /> // This will parse down my default store
  </Provider>

no need to pass persistor to provider. I would recommend reading up more on how react-redux works. Basically if you want access to state you use should using connect. redux-persist will not affect anything about react-redux.
