(Re-filming class review) I watched the newly uploaded 2022.11 video in one day. As expected, it was so informative without a moment of boredom. Above all, I am very grateful for the changed firebase connection and DB data manipulation method, implementing email authentication with firebaseAuth, uploading images with firestorage, etc., and even the iOS build error resolution method. You always help me easily adapt to new changes, and as a lecture purchaser, I am touched by these AS videos. Haha Thank you. It was really helpful as an Android developer. I am very satisfied because I think I reduced my Flutter learning time several times through the core usage of various widgets, problem-solving methods, and the instaclone example and firebase integration that are highly complete despite being an introductory course. I should go to the intermediate level right away. Haha I highly recommend it because there is no reason to go back and forth.
