Flutter Intermediate Part 2 - Practical App Development - US Stock App (with Clean Architecture)

Clean Architecture, Now in Practice!
The key to developing a high-quality Flutter app 👍

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.

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
