Description

In this lab you will be required to demonstrate your ability to create a React Native app with Expo to build an app that contains

basic authentication methods using Firebase. You need to setup your own firebase account with required functionality

$($authentication and database$).$

Use react$-$navigation to navigate between the screens.

Here's what your app should contain:

Requirement

The app's main screen should display a title, email, and

password text inputs.

The main screen also should have two buttons to either login or

register.

The register button takes the user to registration screen.

Registration screen contains four text inputs for first name, last

name, email, and password. There's also a button to register the

user.

The person's first name, last name and email should be saved in

the database is firestore$).$

The login button should navigate the users to Login screen.

The login screen displays a simple message containing user's

name. $($for e$.$g$.,$ Welcome, Nikhil $!)$

In the login screen, check internally if the user's email is verified.

If not, display a button to verify it$,$ which sends an email link

using firebase authentication.

React Navigation is used to navigate between screens

Write the full code for each file. Make it simple. Async Secure Storage NO NEED. Make sure to define a Main screen $($startup

screen$).$

Because the last solution has this error...

Invariant Violation: "main" has not been registered. This can happen if:

Metro $($the local dev server$)$ is run from the wrong folder. Check if Metro is running, stop it and restart it in the current

project.

"A module failed to load due to an error and 'AppRegistry.registerComponent' wasn't called., js engine: hermes
