Why do you initialize the local state with the props.question ? You don't have to do such a thing. Your render() method is use the local state which was one time initialized with the redux store values in the constructor. After that even your siblings are update the store, there is no reason to update the UI since you don't directly use the values from mapStateToProps , instead you use local state which was initialized when the component class is created. Let the actions\dispatchers to update the redux store & use the props.question directly in render() method. In handleClick you are not dispatch new values to the store. It is just update the local state. Instead of doing that, you should ca

You have two main options here, useContext and redux . If you don't have any complex logic and don't need a global state that should be shared across your whole app, go with useContext , otherwise you should use redux who is more complex to implement. The main goal of useContext is to avoid prop drilling, the kind of situation where you pass props between many components. So you wrap all the components that should access the state with a context provider and can get this state from any component who is wrapped by the provider, please read the docs [LINK] to learn more about the useContext. Another option is redux, who is much more complex and probably you will need at least one week to under

This works I believe. I added a button to log your state before and after the change so you can verify that it works. Feel free to remove it, of course. import React, { useState } from 'react'; import { StyleSheet, Text, View, FlatList, Button } from 'react-native'; import ItemList from './itemList'; import Card from '../components/card'; import { globalStyles } from '../Styles/globalStyles'; export default function home({ route, navigation }) { const [list, setList] = useState([ { title: 'Kishal', body: 'asdasdd', reserved: true, id: '1', }, { title: 'Kishal', body: 'asdasdd', reserved: false, id: '2', }, ]); if (route.params) { for (let i = 0; i < list.length; i++) { if (list[i][id] === ro

You only can use the useDispatch hook from a react component or from a custom hook, in your case, you should use store.dispatch() , try to do the following: import { configureStore } from '@reduxjs/toolkit'; import userReducer from './userSlice'; // following the docs, they assign configureStore to a const const store = configureStore({ reducer: { user: userReducer } }); export default store; Edit : i also noticed that you are trying to dispatch a function that is not an action, redux doesn't work like that, you should only dispatch the actions that you have defined in your reducer, otherwise your state will be inconsistent. So first of all, move the fetchAuthUser to another file, like apiCa
