This is not just a good dart tutorial. This is a good introductory video for any programming language. The way you teach is very easy to understand for beginners. I admire that in you!!

i dont understand this part:
final person1 = describe
final person2 = describe
why are you assigning the describe function to person 1/2 and then printing them, when that is what the return function is for?

This is a very good video. I hope to see more of these tutorials. I have been searching online for a good Dart 2 tutorial but there is none. It would be great to touch the advanced topics as well and bring some real example why and when you need to use these features.

Hi, please teach about asynchronous programming in dart

[coalachaos]

IN CASE you have null safety on you have to type: String describe({String? name, int? age, double height = 0.0}) A couple of things have changed with the newer versions. Still, Dart is nice enough to tell you the issue. ;)
