    I developed a deep love for your style of teaching.
    Even though I've learned enough to get my feet dirty with Dart, I'm reviewing Dart through your videos.🎉🎉🎉

    28:26 😮 I can't believe what I just heard. You can reassign final variable with the value of const variable but not the other way around.
    It's understandable, due to the fact that both types hold constant values, although final allows internal mutation.

    Even if I have done some micro projects in Flutter/Dart, because of the lack of constancy I have to study all over again.
    Really, those videos are very good, the way you explain is very clear and I understand what I'm doing.
    I've decided to keep a constancy, although small, of at least one hour a day to be able to improve/gain skills with Flutter and I've decided to upload it to my repository.
    Honestly, if there's a place to start, it's this course.
    Thank you very much!!!

    Quick nitpick for 8:21, in Rust variables are immutable by default and "const" is used for (global) values that can only be computed at compile-time and don't have one memory address associated with them, pretty much like "constexpr" in C++

    20:26 const v/s final:
    You can't reassign const variable or change the internal value of a const variable.
    For a final variable, you can change its internal value, but you can't reassign to it a new value after it's already been assigned.

      Hi. I don’t know how YT algorithms work but I believe they decide how often ads are displayed based on certain criteria because I cannot steer that unfortunately 🥲
