const, final, dynamic, var... when and why? | Dart & Flutter tutorial

One of the first things explained in most tutorials is the declaration of variables. In Dart, you could declare those with const, final, dynamic, var, and by using the type itself; but what are their differences and when should we use each one?

In this video I'll try to define each of them and give you some tips to know which one to use depending on the context.

Thanks for your video. I have a quick question. Const is compile time, does that mean better performance? (even if minimal). Or do you recommend using final for constants.
