This is my error:

• How to solve this error and where is my error I don't know where I do a mistake

• I'm doing a project like an example but it is it gives me an error

• can you give me the suggestion on where I do a mistake and where something happen wrong

• I'm adding redux dispatch and using useSelector in a class component with react native I'm trying to do many solutions but I don't understand properly how to do redux in-class component with react native

Issue

The code in your store.js file is a bit wonky.

1. There is no named configureStore export.
2. A store reference is exported, but it's an odd self-referencing amalgam of createStore and a custom store configurator function.

import { createStore, combineReducers } from 'redux';
import countReducer from './Reducers';

const rootReducer = combineReducers({
  count: countReducer
});

const configureStore = () => {
  return createStore(rootReducer); // <-- calls createStore again??
}

// This is the only export, but it oddly is passed the
// configureStore function instead of the Redux arguments
export const store = createStore(configureStore);

Solution

It's probably best to just create and export the store with the root reducer function.

import { createStore, combineReducers } from 'redux';
import countReducer from './Reducers';

const rootReducer = combineReducers({
  count: countReducer
});

export const store = createStore(rootReducer);

Import store and pass to the Provider component.

import { AppRegistry } from 'react-native';
import React from 'react';
import App from './Redux/App';
import { name as appName } from './app.json';
import { Provider } from 'react-redux';
import { store } from './Redux/store'; // <-- import named export store

const RNRedux = () => (
  <Provider store={store}>
    <App />
  </Provider>
);

I think I should understand your problem.

You make the same name of two components (APP), and you can change one component or screen.

Try this code in your store.js

import { createStore, combineReducers } from 'redux';
import countReducer from './Reducers'
const rootReducer = combineReducers(
    { count: countReducer }
);

export const store= createStore(rootReducer);
