我在 React Native 中的商店遇到了一些問題。我在我的文件 store/index.js 中配置了 store。我將它導出，然后導入 App.js。來自reducer的動作被正確執行，記錄器在瀏覽器調試器中顯示動作，但有一個問題“函數未定義store.getState()。當我在瀏覽器控制臺中輸入“store.getState()”時，我得到一個問題“store未定義”。我不知道可能有什么問題：/感謝您的幫助！我的文件存儲/index.js：import { createStore, combineReducers, applyMiddleware, compose } from 'redux';import { default as mailReducer } from './Mail';import { default as authReducer } from './Auth';import { navReducer } from './Navigation';import { logger } from 'redux-logger';import { composeWithDevTools } from 'redux-devtools-extension';import { combineEpics, createEpicMiddleware } from 'redux-observable';import { middleware as navMiddleware } from "../navigation";const rootReducer = combineReducers({    points: mailReducer,    auth: authReducer,});const initialState = {};const store = createStore(  rootReducer,  applyMiddleware(logger));export default store;我的文件 App.js：import React, {Component} from 'react';import {Platform, StyleSheet, Text, View} from 'react-native';import { createStackNavigator, createAppContainer } from "react-navigation";import { default as NavigationComponent } from './navigation';import store from "./store/index.js";import { IntlProvider, addLocaleData} from "react-intl";import messages_pl from "./formattedMessages/pl.json";import locale_pl from 'react-intl/locale-data/pl';import { connect, Provider } from "react-redux";addLocaleData([...locale_pl]);global.Intl = require('intl');const messages = {    'pl': messages_pl,};const initialState = {};export default class App extends Component<Props> {  render() {    return (      <Provider store={store}>        <IntlProvider locale="pl" messages={messages["pl"]} textComponent={Text}>          <NavigationComponent  />        </IntlProvider>      </Provider>    );  }}
