In this video we take a look at the Dart 2.6 extension method syntax. We look at the various concepts behind the syntactic sugar and their purpose.

Hi Thanks Tensor Flow. I didn't understand the part about toJson/fromJson. What is the advantage of using extension over using factory methods in Person class?

I was really looking forward to this feature (I missed it from C#),
Have you tried running C++ code with dart:ffi?

Calling them "static extension methods" is greatly misleading as it implies that the method attached to the type would be a _static_ method rather than an _instance_ method. This terminology is probably a carry-over from the C# world where extension methods are defined using the `static` keyword, but Dart has no such requirement so there's no reason to refer to extension methods that add functionality to type instances as "static extensions" and doing so just leads to confusion.
(Implementation-wise, these extensions are probably pre-compiled into static methods themselves, but that's an unimportant distinction for the average developer.)

Thanks for explanation! I have some issues though with extensions. I am trying to define some extensions in a separate file within my project. Then when I try to use the extensions in another file, which is even in a separate package, the compiler complains that it can't find the extension... I tried manually importing the file where the extension is located but it doesn't work either, any ideas? THanks!
