rudux with react-native dont work — (0, _combineReducers.default) is not a function

i made exactly same like in react app, but in react is working, in react-native doesnt work

app.js file

import React from 'react';
import { Provider } from 'react-redux';
import { store } from './redux/reducers/combineReducers'

var Stack = createNativeStackNavigator()
export default function App() {
  return (<Provider store={store()}>  // if i write store={store} error: undefined is not an object (evaulating 'store.getStare')


import { key} from "./reducerKey";

    import { combineReducers } from 'redux'
    export var reducers = combineReducers({
        storeKey: key,

reducerKey file

export var key = (state = 0, action) => {
    if (action.type === 'changeKey') {
        return action.playload
    else {
        return state


You didn’t create the store instead you are trying to export the reducer.

In the combinedReducers.js:

import {createStore, combineReducers} from 'redux';

const rootReducer = combineReducers({
   storeKey: key,

const store = createStore(rootReducer)

export {store}

Now in the App.js, you can use the store (without calling it):

import {store} from 'path/to/store';

// rest of the codes ...
<Provider store={store}>
// rest of the codes ...
