Flutter app development ,
Robust with clean architecture 📲

These days, with the increase in Flutter developers, it is not easy to find cases where actual projects are developed with proper architecture . For example, when using the popular GetX library, it is not uncommon to write code that has a dependency on GetX in all layers, such as manipulating the Context in the data layer because of the excessive freedom. In this case, it is difficult to maintain the code, and it tends to become a crude application that is difficult to modify or test functions.

In this lecture
Applying clean architecture
Let's develop a practical US stock app .

Those who are looking at this lecture are those who have taken my lecture 'Flutter Intermediate - Clean Architecture' or those who have equivalent knowledge. In response to the request of students who wanted to cover more real-world examples, I have created a series called 'Real-world App Development' that goes one step further than the last lecture where I covered two examples. I hope this will be an opportunity to learn how to use Provider to restrict freedom and maintain a clean architecture.

Processing data other than JSON
For those who are wondering what to do

In this lecture, we will cover a practical application development example while applying clean architecture to a Flutter app. Clean architecture is

  • 1️⃣ Framework independent
  • 2️⃣ It is easy to test
  • 3️⃣ It is easy to modify or add functions.

Therefore, it can be said that it is an essential concept for developing good apps.


US stock information app
Make it yourself 🛠️

5 features implemented in the app ✨

  • Read US stock information as CSV, parse it, and display it in a list
  • Once loaded, the list is stored in the local DB and used as a cache.
  • Parse JSON data for details
  • The graph is implemented by drawing it directly with a custom painter.
  • Apply Material 3 theme and switch between dark and light mode depending on system settings

After attending the lecture...

  • ✅ You can better understand app development using clean architecture.
  • ✅ You can get a feel for processing data other than JSON.

Check out the Q&A ! 💬

Q. Can I take this course if I don’t know the clean architecture theory?

No, I recommend you take the 'Flutter Intermediate - Clean Architecture' course first.

Q. I am a current Flutter developer. Will this be helpful to me?

If you found the pre-course 'Flutter Intermediate - Clean Architecture' helpful, this course will definitely help you too.

Q. It seems like this lecture doesn't use UseCase, but isn't UseCase essential for clean architecture?

Yes. If there are few functions, Repository is enough instead of UseCase. If you want to try writing UseCase, please do it as homework and share Github. I will review it.

    After watching all the existing Flutter lectures in Korea, I found no lecture that explains Clean Architecture more easily than this one.

      Just like the previous Clean Architecture lecture, it was very informative because it was full of technologies that are really necessary for practical work. I used Hive for the first time and applied Material 3, and the last part where I drew a graph directly using Canvas was really necessary. When developing with Flutter, I tended to take it easy because I depended on libraries a lot, but this lecture made me think that I should make something if I don't like it. It won't be easy, though. Haha. And every time I finish the lecture, I feel motivated to develop. Haha. Please continue to provide lectures that make me feel like I'm learning from a friendly, top-notch senior for a new company project~ Thank you!!!

        Not only was the lecture good, but the communication was also good. Questions were always answered quickly.

          The last lecture was good, but this lecture is also the best. Sometimes when I do Flutter, there are parts that I have to draw myself, and this lecture scratched my itch well. And it's great because it comes up with things I didn't understand well in practice. The part about applying Material 3, which was recently released, was also a great help to people like me who like recent stuff. After taking the lecture, I come back and review it whenever I have questions, and it's great.
