Hello. This is Oh Jun-seok.
I'm announcing the release of a new course.
This course is a short-form format that quickly delivers only the essential points in brief lessons.

The standard that divides the levels of Flutter expertise in practice,

It's the 'environment separation strategy'

Switch environments using only build targets without modifying a single line of code

Break free from the hassle of manually modifying code and the risk of deployment accidents,
and master systematic environment management using Build Flavors and Get_it.

"If you've built a solid foundation through my previous courses, now it's time to experience 'real-world speed'. No lengthy explanations needed. In 2 hours, your project will be perfectly isolated by environment, ready for deployment with just a single mouse click. Short, but the most efficient course in your development career"

Choose 70 minutes of essential practice instead of boring theory

Instead of a long-winded lecture, you'll take away just one solid technique that you can immediately apply in the field: '3-Step Build Separation'.

Flutter, get-it, n8n, Docker usage to
environment-specific independent builds and DI applications - covering practical essentials.

10-Second Coding with AI (Antigravity)

If you have the specifications, Antigravity AI minimizes code typing.

Switch instantly between development, validation, and production environments without modifying a single line of code,
and design the entire process of building your own test server.

'Server-Independent' Development Environment Using n8n and No-code

The time spent waiting for backend developers is too precious. I introduce the tools of a 'complete developer' who combines n8n and AI to build and validate their own Staging server.

Complete your environment setup with pure Dart alone,
and finish with terminal execution in VS Code to complete your practical development experience.
