I bought this while looking for a course that covers both Flutter and Firebase. It was a bit difficult at first because I was new to providers, so I studied the basics of providers and finished it quickly. I'm going to listen to it n times... But I think I need to study providers more to fully understand it..ㅜㅜ First of all, I like that the sound quality is clear and consistent. The text is also neat and readable. And I liked that the instructor explained the reason why the code was done this way while writing it. I also liked the way the code was improved. Since it was an Insta clone course that could implement basic CRUD operations, I think I could use it to create any app. Overall, it was a neat, thorough, and clear course!
