You will develop a basic contact application using Flutter. Your app will allow users to add new contacts, edit or delete existing ones, and all data will be stored on Firebase. Additionally, you will create a login$/$logout system that enables users to sign in and out of the application.

Features:

Adding Contacts:

Users should be able to add new contacts.

First name, last name, and phone number are mandatory fields for each contact.

The email address is an optional field.

Removing Contacts:

Users should be able to remove contacts from their list.

Firebase Integration:

All contact data will be stored in Firebase.

The application should be designed to synchronize with Firebase.

User Login$/$Logout Operations:

Users should be able to log in and log out of the application.

Login will require email and password verification.

Sign Up and Forgot Password:

The login page will include a sign up option for users to create new accounts.

There will be a forgot password option for users to reset their passwords if needed.
