Currently, I have paid for the book review app and listened to the bloc lecture first. There weren't many lectures on Bloc among the status management packages, so it was helpful to be able to listen to good lectures for free. The slightly disappointing part is that I don't know if it's because you explained what you did on YouTube as a free lecture, but the content you wanted to convey was good, but the lecture felt a little unorganized. I felt like it took a lot of time to fix errors or fix things in the middle rather than convey the content, so I felt like I couldn't focus on the bloc content. Of course, doing this process together is helpful, but it felt like it deviated slightly from the purpose of the lecture.
