All lectures must be started with this one. Don't waste money by paying for other lectures such as Flutter, Tass, and Nest. Just finish with this one. The lecture quality is high and the Q&A is really good. The only regret is that there are not many lectures. That's why the quality is good every time a lecture comes out. Like the person below, I trust and watch Code Factory. I predict that in a few years, it will probably become independent from Inflearn.
