No. We will write Cloud Functions in TypeScript.
If and when official Dart support is added to Firebase Cloud Functions, I'll update the course to reflect that.

Course Overview
If you need a backend for your Flutter app, Firebase is the most obvious choice.
Firebase makes it easy to authenticate users, write data to a remote database, and run server-side code securely. And you get scalability and great performance out of the box, without breaking the bank.
But once you start building large-scale apps, things get complicated and you may ask yourself:
- Do I have the right architecture in place?
- Am I structuring my data correctly?
- How can I run complex queries efficiently?
- Are my security rules correct?
- How should I handle errors?
- Will I get a massive Firebase bill and go bankrupt?
In other words - how do you know if you’re doing it right?
Sure, you could read all the docs and watch a ton of tutorials on YouTube - but those often take shortcuts or use examples that are too basic and don't give you the full picture.
As a result, you’re left to learn the hard stuff by trial and error, and that takes ages!
But there's a faster way.
And I can speed up the process for you, by packaging up all my Firebase knowledge and experience into this course.
It's time to
Learn Firebase
This in-depth course will teach you how to create real-world apps with Flutter & Firebase.
Start with the Basics, Then Dive Deep
We'll kick off by building a simple full-stack app that covers Firebase Auth, Cloud Firestore, basic security rules, and the latest Firebase UI packages.
Then, we’ll go deep and build a complex eCommerce application, complete with backend integration using Cloud Functions and 3rd party integrations like Stripe and Algolia.
Along the way, we’ll cover key topics such as:
- Firebase setup with the FlutterFire CLI
- Authentication flows and role-based authorization
- Data modeling, security rules, and CRUD operations with Cloud Firestore
- Queries, indexes, pagination, caching, and offline support
- Image uploads with Firebase Storage
- Firebase Local Emulator and Cloud Functions with TypeScript
- Firebase cost analysis and optimization
- Firebase Extensions and 3rd party integrations (Stripe and Algolia)
- How to securely store client-side and server-side API keys
- Deployment via Firebase Hosting
Course Format
The course contains a variety of code-along videos, along with diagrams and illustrations to help you understand the concepts, as well as full source code, written notes, and additional resources that you can reference later.
Here’s what my past students had to say: 👇
Loved the course and got a lot out of it.
Especially appreciated how Andrea doesn't just show you the "right way" to do things from the start. He shows common errors and pitfalls and how to get around them, and eventually end up at the "right way" with a better understanding of how to actually get there in your own projects.
The course also has a healthy balance of code-alongs for relevant portions and provides you with updated project files throughout, so you don't have to spend hours manually going through every single line of the project.
I finally finished Andrea's two main courses. It is hard-core and very intensive; unlike the other introductory courses, Andrea's courses are very clear and hit the objective directly.
Most importantly, the quality of the code is very high and is also based on the most updated SDK versions. Just looking through the code makes me feel very pleasant.
It's only my first time going through the code; I'll do it more times and try to finish the app, not following the course closely.

Intended Audience
Who is this course for?
This is an intermediate to advanced-level course about Flutter & Firebase, and you need to be already familiar with Dart, Flutter, GoRouter, and Riverpod to make the most of it.
We’ll start by building a simple full-stack app so you'll get comfortable with the basics even if you never used Firebase before.
Then, I’ll give you a detailed walkthrough of the complete eCommerce app that was covered in the Flutter Foundations course. And we’ll turn it into a full-stack app, using the Firebase Dart packages on the frontend, and Cloud Functions with TypeScript on the backend.
When adding new features, I'll include most of the UI code beforehand so we can focus on what matters most: learning Firebase.
While this is not strictly required, I recommend you take the Flutter Foundations course before proceeding to this one.
FAQ
Frequently Asked Questions
How much does the course cost?
The Flutter & Firebase Masterclass costs $129 (unless a promotion is ongoing).
Will you offer discounts in the future?
From time to time (e.g. Black Friday) I offer discounts, however these are very infrequent.
If you want to get value from the course, your best option is to buy today. If you're not satisfied, you can get a refund within 30 days of purchase.
Should I take the Flutter Foundations course before this one?
While this is not strictly required, I recommend taking the Flutter Foundations course before proceeding to this one.
If you wish, you can buy both courses together on the checkout page.
Can I buy all three courses as a single bundle?
This is the second course in a series of three:
- Flutter Foundations Course
- Flutter & Firebase Masterclass
- Flutter in Production
Once the last course is published, you'll be able to buy all three as a single bundle.
But for now, you can buy the first two courses together on the checkout page.
How long is the Flutter & Firebase course?
This course is 12 hours long.
Is the course up to date?
Yes. The course was last updated in April 2025 and is compatible with the latest versions of Flutter and Firebase.
I'll continue to keep it up to date in the future.
Will this course cover all the Firebase products?
Firebase is a big platform that includes many different services to build, release, and monitor your apps. And it would be hard to cover them all in a single course.
So here’s a list of topics that are not planned for this course:
- Firebase Remote Config
- Firebase Dynamic Links
- Firebase Cloud Messaging
- OAuth providers (Google, Apple, Facebook etc.) and advanced authentication features
I will, however, cover some of these topics in future articles or courses.
Will you cover any backends other than Firebase?
This is not currently planned, though I may create additional courses for other backends in the future.
We will design the Flutter codebase with good separation of concerns, making it easier to adopt a different backend if desired.
Will this course cover server-side Dart?
What about payment providers other than Stripe?
Stripe and RevenueCat are the only payment processors with good support for Flutter on iOS, Android, and web.
Since we'll build an eCommerce app to sell physical products, Stripe is the ideal choice.
I may cover other payments providers as part of separate courses in the future.
What if I get stuck? Can I ask questions?
Yes. You can ask questions on the course Q/A in the Discord server. I answer most questions within 24 hours.
Will I get a completion certificate?
Sure do! Once you complete the course this will be issued to you automatically.
I'm a student / I can't afford the course / I live outside the US/EU / do you support Purchasing Power Parity (PPP)?
Unfortunately PPP is not supported by my course platform. If you'd like to request a discount, please fill this form.
Can I gift the course to someone else?
Yes! Here are two simple options:
- During checkout, enter the recipient’s email address. They’ll receive the welcome email and access to the course. Note: They’ll also get a copy of the invoice, including the last 4 digits of your credit card (if paying by card).
- Purchase under your own email, then email me with the recipient’s name and email. I’ll transfer the course access to them. Note: This option keeps your invoice private, but it might take up to 1–2 business days for me to process.
I bought the essentials package. Can I upgrade to the complete package?
Sure - email me at courses@codewithandrea.com and I'll send you a coupon that you can use to upgrade to the full package.
