Course Description

Do you want to build a real-world, scalable multi-vendor mobile app using Flutter and Node.js, complete with online payments?

In this course, you’ll learn full-stack mobile development by building a complete multi-store (multi-vendor) application from scratch, using Flutter for the frontend, Node.js and Express for the backend, MongoDB for data storage, and Stripe for secure online payments.

This is not a demo or a basic CRUD app. You’ll build a production-style application with real business logic and advanced features used in modern e-commerce and marketplace platforms.

By the end of this course, you will have a fully functional multi-vendor mobile app with:

  • Flutter mobile app (Android & iOS)

  • Node.js + Express backend

  • MongoDB database

  • User authentication and authorization

  • Multi-store / vendor management

  • Product and category management

  • Shopping cart and checkout system

  • Stripe payment integration

  • Order and payment tracking

  • RESTful API integration

  • Clean, scalable project architecture

You’ll learn how to build modern mobile UIs, structure scalable projects, connect the frontend to backend APIs, implement authentication and user roles, integrate Stripe payments, and handle real-world app flows like checkout and orders.

This course gives you practical, production-ready skills you can use for jobs, freelancing, or building your own apps confidently and efficiently.

The instructor stumbled over his words numerous times, speech was hard to understand, he backed track over explanation like he really did not understand the concepts but was reading from something written on paper

By Abhinandh B on 4/1/2025

The course is not beginner friendly and also the tutor sometimes misses important contexts about the topic which I had to use chatgpt to understand. If you have some experience in making own backend projects and want to upskill then this course is definitely worth it.

By Nazrul Islam on 8/31/2024

I am thoroughly enjoying this course Macualay is an outstanding tutor who explains every line of code clearly while writing and provides a helpful summary at the end. The teaching style is engaging and informative ❤️‍ I have no complaints and highly recommend this course to anyone looking to master of Flutter with Node.js and Express

By Abdoul Diop on 8/29/2024

this course by Macaulay Famous . I couldn't be more impressed! From the very first lesson, it was clear that he is not only knowledgeable about the subject matter but also passionate about teaching.The course material was well-organized and comprehensive. Each module built upon the last, making complex concepts easy to understand. I particularly appreciated the real-world examples that helped clarify theoretical points.

By Mark Zeiger on 7/25/2024

Macualay does a really great job of explaining everything. I took a course in Flutter and MongoDB previously and the API was quite complex. Macaulay's explanations and code were much easier to understand. One small comment: Don't end the video milliseconds after the last word. Give it a couple of seconds so that we can finish the section without having to rewind the video. Otherwise you're doing great.

By Ritik Prajapati on 7/10/2024

First of all, I am loving this course. I can say, without any doubt, that Macualay is a great tutor explaining each line while writing and also giving a summary of the whole code at the end. But I have a question, I had to learn node.js and express in flutter but I had very limited time and when I purchased this course, this showed only 12 hours course but now I see that the tutor is continuosly adding new videos almost daily. Again clearing myself, I have no complaints from the course, I just wanted to know how long this course approximately might get. It would be really helpful if you could just respond to my query.

By Custódio Serafim Langa on 7/6/2024

Até agora, está excelente. Esta tem sido uma experiência ótima para mim. Tradicionalmente, trabalhei com desenvolvimento web, e este é o meu primeiro contato com o desenvolvimento mobile. O curso tem sido muito didático e fácil de acompanhar.

By Kingsley Otedjere on 6/26/2024

His teaching method made even the most challenging topics easy to understand and follow. By using clear examples and practical applications, the tutor ensured that each lesson was accessible and engaging. He is patient and thorough, taking the time to address any questions and reinforce key points. This approach helped students grasp the material more effectively and gain confidence in their understanding of the subject.
