How to display image from device library in React Native mobile app?

Issue

I am trying to implement a functionality where it allows the user to tap the "Add Photo" component and their device photo library pops up to add/choose an image to display. However, I am testing this and although my console.log(result) seems to be working & outputting fine it is not displaying the image, the component stays the same as I have upon startup (check image attached). Note, I am using expo with IOS simulator, I also wanted to ask if implemented correctly, is it maybe a simulation environment causing this to not display?

User Profile.js:

import React, { useState, useEffect } from 'react';
import { View, Text, TextInput, TouchableOpacity, Image, StyleSheet, ScrollView } from 'react-native';
import * as ImagePicker from 'expo-image-picker';
import Icon from 'react-native-vector-icons/FontAwesome';
import * as Localization from 'expo-localization';

const Profile = ({ route }) => {
  const user = route.params.user.user;
  const [username, setUsername] = useState(user.username);
  const [password, setPassword] = useState(user.password);
  const [email, setEmail] = useState(user.email);
  const [phoneNumber, setPhoneNumber] = useState('');
  const [profileImage, setProfileImage] = useState(null);
  const [showPassword, setShowPassword] = useState(false);
  const [joinedDate, setJoinedDate] = useState(null);
  const deviceLanguage = Localization.locale;

  const pickImage = async () => {
    try {
      const result = await ImagePicker.launchImageLibraryAsync({
        mediaTypes: ImagePicker.MediaTypeOptions.Images,
        allowsEditing: true,
        aspect: [4, 3],
        quality: 1,
      });
      if (!result.cancelled) {
        setProfileImage(result.uri);
        console.log('Image picker result:', result);
      }
    } catch (error) {
      console.log('Error picking image', error);
    }
  };  

  const handleSaveChanges = () => {
    console.log('Updated Data:');
    console.log('User Name:', username);
    console.log('Password:', password)
    console.log('Email:', email);
    console.log('Phone Number:', phoneNumber);
    console.log('Image:', profileImage);
  };

  useEffect(() => {
    (async () => {
      if (Platform.OS !== 'web') {
        const { status } = await ImagePicker.requestMediaLibraryPermissionsAsync();
        if (status !== 'granted') {
          alert('Sorry, we need camera roll permissions to make this work.');
        }
      }
    })();
    
    const currentDate = new Date();
    const formattedDate = currentDate.toISOString().split('T')[0];
    setJoinedDate(formattedDate);
  }, []);

  return (

I tried debugging and this is the output for console.log(result) on line 28:

Image picker result: Object {
  "assets": Array [
    Object {
      "assetId": "99D53A1F-FEEF-40E1-8BB3-7DD55A43C8B7/L0/001",
      "base64": null,
      "duration": null,
      "exif": null,
      "fileName": "IMG_0004.JPG",
      "fileSize": 2321139,
      "height": 1668,
      "type": "image",
      "uri": "file:///Users/besabunjaku/Library/Developer/CoreSimulator/Devices/B3DC7595-6F7F-44A4-874E-B96D527973B3/data/Containers/Data/Application/83A2BCEE-AB17-4A5C-AC82-012BC9617172/Library/Caches/ExponentExperienceData/%2540anonymous%252FHalaFinds-9c96a55d-e687-44f0-afcb-48668cf9406a/ImagePicker/02AB4D6E-AFFA-4E06-9B22-5CA87261A85A.jpg",
      "width": 1668,
    },
  ],
  "canceled": false,

Solution

The result contains the Array named assets, but you treat it as the Object, hence it's cause problem, to fix it, just use:

setProfileImage(result.assets[0].uri);
