Dart Functions - Introduction to Functions 

Johan, you explain things very clearly. Thank you and greetings from Texas.

Currently taking a dart course and got stuck at functions, grateful I found this tutorial.

I can't believe how much I have learnt. I really like your approach. Before I started this playlist I knew nothing about coding. I am the one explaining to my friends now. 😆 Thanks Johan

Gorgeous Voice!! You are a best teacher. Always respect🙏

Best teacher so far. Thanks for sharing your knowledge

very nice course collection especially for review Flutter/Dart experience .Thank you Johan and Huge Thank you for your easyly understandable English :))

thanks you very much

Can someone please recommend a website where I can practice coding in Dart. Thank you!

hey thank you for the great tutorial, it is really helpful! I was getting one problem with this example and it is about nullable types. my function is not working. I also tried ?? and !, ? but I always see the same error. calculateDiscount says "The body might complete normally, causing 'null' to be returned, but the return type, 'int', is a potentially non-nullable type. Try adding either a return or a throw statement at the end." I tried add try, catch but it does not looks work. Thank you. Does anyone faced this issue?

how about to use import dart:io?

👍
