The detailed explanation was good. But this lecture doesn't seem to be for beginners. I learned a lot and listened well.

I took both the KakaoTalk and Instagram courses. I thought there would be a lot of overlapping content, but it seems like the instructor put a lot of effort into including new things to learn in each course. Thank you for the great courses.

I listened to it all the way through the first time, and followed it from beginning to end the second time. Overall, it was a clean source without any unnecessary details, so it was a great lecture to study and I was able to learn a lot. However, one thing that is disappointing is that despite being a Flutter lecture, it is only available for the Android version. If only this part could be improved, I am confident that it will be an excellent Flutter lecture that includes almost all the functions related to chat. Thank you for your hard work preparing the lecture.

          Previously, I had only made several simple apps with Flutter, but I always felt like something was lacking. This time, through the chat app creation lecture, I was able to implement app functions that can be used in real life, which was very helpful. I had a hard time because I didn't know how to use riverpod, but I was able to study while watching the lecture and thinking about how state management is used. If you are a beginner in Flutter and are stuck, I would definitely recommend this lecture!!
