Let's get started with a question
What is Firebase?
Firebase is a set of hosting services for any application. It offers NoSQL and real-time hosting of databases, content, social authentication, notifications, or services, such as a real-time communication server.
Let us have a glimpse of Firebase 🔥, and all the tools and services that it provides :
:: Build Better Apps — Firebase lets you build more powerful, secure and scalable apps with the help of firebase functionalities like Cloud Firestore , ML Kit , Cloud Functions, Hosting , Authentication , Cloud Storage , Real Time Database enhancing the app quality and monitor performance .
:: Improve app quality — Firebase gives you insights into app performance and stability, so you can channel your resources effectively using functionalities like Crashlytics , Performance Monitoring , Test Labs .
:: Grow your business — Firebase helps you grow to millions of users, simplifying user engagement and retention using it’s functionalities like In-App Messaging , Google Analytics , A/B Testing , Predictions , Cloud Messaging(FCM) , Remote Configuration , Dynamic Links , App Indexing

FIREBASE AUTHENTICATION:
Firebase Authentication is a service provided by Firebase that allows you to authenticate users who use your app. It supports a variety of authentication methods, including email and password, third-party providers like Google and Facebook, and even phone numbers. Firebase Authentication makes it easy to add authentication to your app and manage the users who are signed in. It also provides a number of security features, such as password hashing and firewalls, to protect your app and its users.
Yes, it is possible to use Firebase Authentication with Flutter. Firebase provides a plugin for Flutter that makes it easy to use Firebase Authentication in your Flutter app. To use Firebase Authentication with Flutter, you must install the firebase_auth package from pub.dev and configure your app to use Firebase. Once you have done that, you can use the Firebase Authentication API in your Flutter app to authenticate users and manage their accounts.
FIREBASE AUTHENTICATION:
We will also learn how to use the firebase auth service to perform authentication. We will cover authentication using the following providers:
- EMAIL PASSWORD AUTHENTICATION[ Signup, Sign in, Verify the user’s email and Reset the password]
- PHONE AUTHENTICATION [OTP]
- GOOGLE AUTHENTICATION
- TWITTER AUTHENTICATION
FIREBASE REST API AUTHENTICATION:
We will also learn about how to integrate firebase auth REST API with our flutter apps. We will use the provider state management helper to manage the app’s state. We will explore the following feature:
- Sign up and sign in
- Save user data to local storage
- Auto Logging in user
- Update user name and photo URL
- Forget password
- Change password
- Logout
- Exception handling
FIREBASE CLOUD FIRESTORE:
Firebase Cloud Firestore is a cloud-based NoSQL database provided by Google as part of the Firebase suite of services. It allows developers to store and query data in real time and provides a number of powerful features such as automatic scaling, offline support, and real-time data synchronization across multiple devices. Firestore is designed to be easy to use and integrate into a variety of different applications, and it is often used as the data store for mobile and web apps. It supports a variety of data types, including strings, numbers, booleans, and even complex objects and arrays.
Firebase Cloud Firestore is a powerful, flexible, and scalable database for mobile and web app development. With Firestore, you can store and query data in real-time, and make your app more responsive and offline-friendly. Some of the key features of Firestore include:
- Realtime data synchronization: Firestore automatically synchronizes data across all connected devices in real-time, so your app always has the latest data.
- Offline support: Firestore allows your app to continue working even when the user’s device is offline, and it automatically synchronizes any changes made while offline once the device is back online.
- Automatic scaling: Firestore automatically scales to support large amounts of data and high traffic, so you don’t have to worry about performance as your app grows.
- Easy integration: Firestore is designed to be easy to use and integrate into a variety of different apps, and it provides libraries and SDKs for popular platforms such as Android, iOS, and the web.
These features make Firestore a powerful and convenient choice for storing and managing data in your app.
In this module, you will learn about the CRUD operation using the cloud firestore database.
- Read the data from the cloud firestore database.
- Write the data from the cloud firestore database.
- Delete the data from the cloud firestore database.
- Update the data on the cloud firestore database.
FIREBASE REAL-TIME DATABASE:
Firebase Real-time Database is a cloud-based NoSQL database provided by Google as part of the Firebase suite of services. It allows developers to store and query data in real-time, and provides a number of powerful features such as automatic scaling, offline support, and real-time data synchronization across multiple devices. The Firebase Real-time Database is designed to be easy to use and integrate into a variety of different applications, and it is often used as the data store for mobile and web apps. It supports a variety of data types, including strings, numbers, booleans, and even complex objects and arrays. The key difference between Firebase Real-time Database and Firebase Cloud Firestore is the way data is structured and queried. While Firestore uses a document-oriented data model, the Real-time Database uses a more traditional hierarchical data structure. This means that the Real-time Database is better suited for certain types of data, such as large collections of small objects, while Firestore is better for others, such as complex nested objects.
- Realtime data synchronization: The Real-time Database automatically synchronizes data across all connected devices in realtime, so your app always has the latest data.
- Offline support: The Real-time Database allows your app to continue working even when the user’s device is offline, and it automatically synchronizes any changes made while offline once the device is back online.
- Automatic scaling: The Real-time Database automatically scales to support large amounts of data and high traffic, so you don’t have to worry about performance as your app grows.
- Flexible data model: The Real-time Database uses a document-oriented data model, which allows you to store complex data structures and query data using a powerful and flexible query language.
In this module, you will learn about the CRUD operation using real-time database REST APIs.
- Read the data from the real-time database.
- Write the data from the real-time database.
- Delete the data from the real-time database.
- Update the data on the real-time database.
Realtime database vs Cloud Firestore:
Here are some key points to consider when comparing Firebase Realtime Database and Firebase Cloud Firestore:
- Data model: Firebase Realtime Database uses a JSON data model, while Cloud Firestore uses a more flexible, document-oriented data model.
- Performance and scalability: Firebase Realtime Database is optimized for high-write workloads, while Cloud Firestore is optimized for complex queries.
- Pricing: Both databases have a free tier and paid tiers with pricing based on usage.
- Use cases: Firebase Realtime Database may be a good choice for applications that require high-write performance and can benefit from the simplicity of a JSON data model, while Cloud Firestore may be a better choice for applications that require complex queries and can benefit from the flexibility of a document-oriented data model.
- Other factors: Other factors to consider when choosing between the two databases may include the specific requirements of your project, the size and complexity of your data, and your overall goals and objectives for the application.
