A very good lecture that systematically organizes the full stack process across the whole and elements so that even beginners can easily follow it! The connection between the big picture and the detailed code is outstanding!!

This is a great course for getting started with Flutter! It's not just about using the grammar of the language, but it's also great because it covers planning and design elements when creating an app from scratch. I'm currently finishing up the front-end part, and as a programming beginner, I especially liked Section 10! This part gave me a chance to think about logic, so I've been watching it over and over again! I'm also looking forward to the back-end and database parts! Good luck to Janjaemi Coding, who I trust and take classes with~~

Thank you for the great lecture. As someone who gave up on learning Flutter several years ago, I was able to complete it after meeting a good lecture. As a semiconductor major who has studied only hardware for 35 years, the area I always felt lacking was software and full-stack design technology. I started studying to create a department server, but after going through the full-stack roadmap process, I think I will be able to implement various services than my initial goal. Please continue to provide good lectures.

What you will gain after the course

  • Learn the Basics of the Dart Language

  • Understanding the Basics of Flutter

  • Learn Basic and Intermediate Flutter Widgets

  • Firebase/Firestore Integration with Flutter

  • Building a Plausible Service with Flutter/Firebase/Firestore

A high-quality course that teaches you step by step, from Dart programming to hands-on Flutter projects

created by Dave Lee of Fun Coding.

The Dave Lee course by Fun Coding, chosen by Naver, Kakao, Line, Coupang, and Baemin for internal employee training

Based on the instructor’s own early experiences of failure and trial and error, this course is designed to help you learn and practically use Flutter, starting with no prior knowledge of it.

Flutter is recommended for people like these

  • Those who want to develop websites, apps, and programs for Mac/Windows PCs based on their own ideas as a small startup.
  • Those who want to learn the latest popular technologies as frontend developers
  • Those who want to get a job as a Flutter specialist developer
  • Those who want to build frontend skills to become a senior developer
  • Those who want to become full-stack developers

Flutter, developed by Google, lets you build web, mobile, and PC programs
all from a single codebase—and make them look great, too

👉 If you have experience with just one programming language, you can learn Flutter!
* If you have no programming experience at all, we recommend taking the Python programming basics course as well, following the full-stack roadmap at the bottom of this page!


Introduction to the Fun Coding Flutter Course and Its Advantages

  • 잘 정리된 문서를 기반으로 영상을 통해 설명합니다.
    • That way, after the course, you can quickly find and use the features you’ve learned whenever you need them.
  • You will learn Dart, Flutter's underlying language, by solving problems along with explanations to build a strong foundation.
  • 위젯마다 주요 사용법을 익히고, 엮어서 그럴듯한 화면을 만듭니다.
    • That way, you’ll get a feel for it, and the widgets you’ve learned will gradually become familiar.
  • Flutter 개발에 chatGPT 를 활용하는 방법까지 익힙니다.
    • By leveraging AI, you can create the code you want in Flutter much faster.

👉 Ultimately, we designed the course so that by the time you finish it, you’ll think, 'I can really use Flutter'.


The instructor incorporated the shortcuts discovered through numerous failures in their entirety.

  • 하나의 기술을 내 것으로 만들기는 쉽지 않습니다
    • Flutter is a new technology, so there aren't many resources available, and above all, it's unclear how to learn it.
    • Even after reading books or watching YouTube videos, it can still feel unclear—you may or may not understand it.
  • 그럴듯한 화면을 만드는 코드를 많이 본다고 익혀지지는 않더라고요!
    • Focusing on key code patterns and features
    • I found that you really learn it by breaking things down one by one and putting them to use!

👉 Follow the course in this order. Once you get past the halfway point, things will gradually start to click, and you’ll gain confidence!


We also explain backend features (Firebase) so that you can build a complete service with Flutter.

  • 하나의 서비스는 결국 프론트엔드와 백엔드 기술이 필요합니다.
    • Flutter is a frontend technology, so to build a complete service, you also need to learn backend technologies.
    • This course also covers techniques for using Firebase, a backend that pairs well with Flutter. You will also build a functional service.


Flutter development becomes much easier when you use ChatGPT.

  • The course also covers how to use AI in Flutter development.

👉 By building a solid foundation in Flutter through this course and leveraging AI, there’s no service you can’t create!

For those who want to learn development
systematically
, we also provide a full-stack roadmap.

  • IT technologies are interconnected, so you need to learn them systematically to gain practical proficiency.
  • If you’re finding it difficult to learn each IT technology from different instructors with varying levels of difficulty and curricula, or even casually through YouTube!

We have summarized the fastest, most up-to-date full-stack roadmap in a YouTube video. By referring to it, you can understand the roadmap to web/app development on your own in a short time.

👉 Try just one of the courses on the technology you’re interested in~ If you feel that it’s different, take them step by step in the order of the roadmap. The difficulty increases gradually, helping you effectively learn interconnected technologies.


I have been creating IT courses for eight years while working in the industry.
I create them with substantial content at a reasonable price.

Based on well-organized documentation, we explain everything through videos.
That way, after the course, you can quickly find and use the features you have learned whenever you need them.

  • All Flutter example code is provided as files.
  • You can refer to the Flutter documentation materials anytime in PDF format, like an ebook.
    (However, copying and downloading are restricted due to copyright concerns.)

Examples of polished screens and projects created within the course
(In addition, we create sample code for each widget and syntax element.)


Learn systematically
Dave Lee's roadmap from Fun Coding

Following this course, AI, development, data, and CS roadmaps you can learn according to your goals

IT technologies are interconnected.
By selectively learning connected technologies and adding AI to the mix, you can reach your goals much faster.

Every roadmap covers how to connect and use technologies together,
is designed to increase in difficulty from the beginner level to the expert level, and
is continuously updated over the years.

You’ll also receive a greater discount than when taking the courses individually.

    Thank you so much for the informative lecture. I am taking all of the lectures of Mr. Janjaemi Coding, including Infraon, and even on individual homepages, except for Java. They are really helpful. What are your plans for future lectures? Personally, I think that if I master the full-stack part and the data science part, the only thing left is IoT, so I would like to take IoT-related lectures as well.

      I don't think this lecture is aimed at completely conquering Flutter. However, I think it is a lecture that builds a solid foundation of Flutter in the shortest time possible and then shows you what to learn next. Of course, there are people who can make great apps by just listening to this lecture, but at least I wasn't like that. However, I think it is a lecture that lets me know what I lack and reduces the need to make efforts to fill in the gaps. For example, when I wanted to add a calendar to my app and read the table_calendar document, I didn't have to be confused because I didn't understand it at least. I think this was the goal of this lecture. I don't think this lecture is for people who think they can make everything with this lecture. However, if you are someone who can study step by step while listening to this lecture, I think there is no better lecture. For a total of 26 hours, I didn't know anything about Dart, but now I can read some API references and fill in the gaps. Thank you so much for the great lecture.

      As expected, he gives an interesting lecture. I find that his lectures are strangely easier to understand if I watch a similar lecture on YouTube before listening to them. I am not a professional or a major in this field, but I am listening to it as a way to broaden my horizons. Listening to coding makes me feel more logical. Since I don't go out for drinks often, I can listen to interesting lectures by drinking less alcohol~😊
