React Native useContext hook returns Undefined - react-native

Question

I am new to react native and context Api so any help would be really appreciated. When I start the app I see undefined is not an object _useContext.appUser error. Below is my code.
App.js
import { AsyncStorage } from 'react-native';
import { NavigationContainer } from '#react-navigation/native'
import AuthStackNavigator from './src/navigators/AuthStackNavigator'
import { LightTheme } from './src/themes/light'
import UserTabsNavigator from './src/navigators/UserTabsNavigator'
import AuthProvider from './src/auth/AuthProvider'
import { AuthContext } from './src/auth/AuthProvider';
export default function App() {
const [loggedIn, setLoggedIn] = useState(false);
const { appUser } = useContext(AuthContext);
console.log('context object' + appUser);
useEffect(() => {
AsyncStorage.getItem('user').then(userString => {
if (userString) {
setLoggedIn(true)
}
}).catch(error => {
console.log(error);
})
})
return (
<AuthProvider>
<NavigationContainer theme={LightTheme}>
{loggedIn ? <UserTabsNavigator /> :
<AuthStackNavigator />}
</NavigationContainer>
</AuthProvider>
);
};
AuthProvider.js
import React, { useState, createContext } from 'react';
import { AsyncStorage } from 'react-native';
export const AuthContext = createContext();
const AuthProvider = ({ children }) => {
const [user, setUser] = useState(null);
const loginUser = () => {
const fakeUser = { username: 'Test' }
AsyncStorage.setItem('user', JSON.stringify(fakeUser));
setUser(fakeUser);
}
const logoutUser = () => {
AsyncStorage.removeItem('user');
setUser(null);
}
return (
<AuthContext.Provider value={{
appUser: user,
login: loginUser,
logout: logoutUser
}}>
{children}
</AuthContext.Provider>
)
}
export default AuthProvider;
I would really appreciate any help here. I have been struggling with this issue for a while now. I am kinda stuck here.
