- Hi there!
In this video I'll make you a complete introduction to Dart Functions. You'll learn everything you need to know regarding named & anonymous functions (known as lambdas & closures), all types of parameters a function can take (positional & named). You'll also get a brief over the scope of a function and lexical closures.

the double brackets ()() hint at the end of the video is neat 👌
Thank you so much, brother, I am glad you observed it! 🌟
Thanks
Very very good tutorials. I bet you have read some Dart documentation that even Dart creators haven't read yet :)
Haha, thank you so much, man! ✨
Bullseye! 🎯
Amazing 👏.
Bro can suggest some books on Dart and flutter?
Not to speak for him, but I think "Dart Apprentice" by Jonathan Sade & Matt Galloway looks like the best book on Dart itself.
@@davidowens9597 Thanks man
I am a javascript dev.I am learning Dart.And honestly so far,your course playlist is just amazing.I've found so many Dart courses on youtube.But most of them just scrace on the serface.You really consider your viewers as a dev who are learning Dart as there 2nd or 3rd langguage.
I've one recommendation.Please make the font-size a bit larger as it's really hard to see the text.
I have a question too.you are referring the lamda as a closer too.I am not sure,are all lamdas are closer in Dart?Like in javascript,a scoped function is only a closer when it enclosed it's parrent's local variable.Otherwise it not act like a closure.In this video,the lamda function in map is not enclosing any parent local variable,it justi run bassed on arguments that are given by the parrent function-in this case it the map function.Please make it clear.
Thank you
At 4:16 and 4:39 you say: "a type of void". But the 'void' seems to be a different animal on the Dart type hierarchy tree. Is it a class? Can you instantiate an object out of it? We know that 'void type' cannot hold any values (not even a null?). So is it a primitive? (Like in C language) So what gives.
Anyway, this is an exquisite course. Thank you for all your hard work!!!

Thanks, brother! ✨
Thanks, but please consider dropping the periodic "please subscribe" pop-ups - it's very distracting.
yet another great tutorial with clear, detailed and easy to follow. Keep helping dart programmers. WCKD!. 1000x👏
Thank you so much, brother! ✨
