Flutter This is a lecture that opened the door for those who are just starting out and want to do something at the beginner level. If someone who doesn't know Dart or Flutter's logic is listening, it might be difficult because it goes by too quickly and the explanations aren't detailed, but this lecture doesn't seem to have been made for beginners in the first place. It seems to be a very suitable video for those who already know Dart or Flutter's logic. It's made very simply, but you'll learn a lot about backend API integration and other useful functions for actual use.
