Answer 1

faker is deprecated first remove your old package

npm uninstall faker

then get a new package

npm install @faker-js/faker --save-dev

and import it like this

import * as faker from 'faker';

import * as faker from '@faker-js/faker';

check here for more info

Answer 2

npm install --save-dev faker@5.5.3

this will solve the issue

Answer 3

import { faker } from '@faker-js/faker';

//single random user profile generator
function randomProfile() {
    return {
        userId: faker.datatype.uuid(),
        username: faker.internet.userName(),
        email: faker.internet.email(),
        avatar: faker.image.avatar(),
        password: faker.internet.password(),
        birthdate: faker.date.birthdate(),
        registeredAt: faker.date.past(),
    }
}

//define a method to generate users up to 'max_size' amount
const profile = function (max_size) {
    const  users = [];
    for (let index = 0; index < max_size; index++) {
        users.push(randomProfile());
    }
    return users;
};

// actually generate 10 random user profiles & load them in 'users_group' variable
const users_group = profile(10);


const Home = () => {
  return (
    <View style={{flex: 1, backgroundColor: '#fff'}}>
        <StatusBar hidden/>
         {/* out of the 10 user profile generated use the avatar(Image) of the first user*/}
        <Image source={users_group[1].avatar} />

         {/* out of the 10 user profile generated use the second avatar(Image) of the first user*/}
        <Image source={users_group[2].avatar} />
        <Text>Hello{profile.avatar}</Text>
    </View>
  )
}
