I first studied Flutter through a book and immediately signed up for an intermediate course, and as expected, it was so, so difficult. I was following along well, but I felt that my overall concept of Flutter was very immature, starting with the generalization part using OOP, so I realized the need for repeated review. I think that if I acquire this part firmly, then there will be a lot of growth in programming in general, not just Flutter. Thank you so much for creating such a useful lecture. I think that the Flutter community in Korea is growing because you create such great lectures! Since I started getting started with Flutter through Code Factory's YouTube videos, books, and lectures, I will continue to look forward to good lectures and always cheer you on while I am using Flutter!! Thank you so much!!!
