This is the clearest demonstration of classes and constructors in all of recorded history.

Net Ninja: declares that he won't explain the basics of programming Also Net Ninja: explains the basics of programming

For anyone who is confused around 21:30. They added a new keyword "late" in 2.12 which is now necessary to put before String and int under class User. Should look like this: late String username; late int age; Late means that the variable is not called until it is referenced for the first time

The fact that you put out this level of quality content for free is mind-boggling to me

The best demonstration of classes and constructors on youtube. And the best accent, too. Please keep the good work on.

I've been a c++ and java guy for two years, and it feels like that dart is just a baby of both. And the way you explained it, felt damn easy.

The video is 27 minutes but feel likes its omly 2 minutes ...you are really a ninja in tech...awesome class explanation

Flutter added a whole lotta new stuff with 2.0 including Null safety that doesn't let you initialize types with a null value. So if you wanna get rid of that, uncheck the Null safety feature in Dartpad in the bottom-left

i had to pause this video to take a moment to write this comment, great stuff man thank you very much for providing such premium content for free.

I think this video was before the 'late' keyword was released in dart 2.1. That is why I keep having errors in the class scope. In Dart, we use the late keyword to declare variables that will be initialised later. If you're having errors in 21:09 , just add 'late' before your two variables in the class scope. Thanks!

You are extremely eloquent, my friend! Clear and concise. Very excited to see where this course goes!

Going through this now in 2021 and noticing for part 3 that the User Method Function doesn't work unless you make the String and int nullable by adding a ? after String and int. Apparently this is because Dart 2.12 introduced Null Safety. Figured I'd comment since I ran into this problem and this was how I solved it to get the same results.

A quick rundown on Dart basic types, classes, constructor functions and even inheritance. What a gold mine of knowledge inside a 30 min long video! Best Dart primer I've seen among all internet content, ever!

Dude, this intro was loaded, I understood very well mixing my arduino-c++ and JS coding skills, Again thanks this series. Greetings from Tanzania 🇹🇿

I've never seen anyone explaining about classes, method and inheritance this much clearly. 👏👏👏👏

You are explaining in the simplest form .I dont think any one will be able to simplify than this.Even a person doesnt know basics of programming can understand .Thank you so much.

Definitely the clearest explanation about the basics of programming, even you are not into Flutter you can still watch this video to understand the logic of programming.

These videos are great. I come from 10+ years of writing Python and these videos are helping me understand syntax differences between Python and Dart. I feel like Im finally starting to have the ability to read Dart code without feeling lost in the syntax.

This helped me so much not only with learning to use flutter, but also with my understanding of object oriented programming in general. Thank you!

i started in ionic and its a hardcore learning curve on every tutorial ive watched. while this one is so step by step THANKS A LOT.

Thank you very much. I started React with your videos. Now am almost an expert in React. Built a project using React and Relay Modern. Now I am starting my first steps in Flutter with you. Thanks again!

Cleared most of Classes and Objects concepts in just few minutes. JazakAllah! Nice content!

I know this is 4 years old, but just wanted to say that I've brute forced learning java and C# for Unity for a few years and no tutorial I've seen has explained the basics of coding as well as you have in this video. Things I've been told, like just writing like Void or adding to define the data type of a List, I've always just nodded as others have skipped over explaining what they actually do. This video alone has just made so many things I've memorized as necessary, but never understood, just click in my brain with comprehension. Thanks so much for making this series. Excited for the rest! Cheers!

the way of EXPLAINING is very-very cool, awesome. Precise and to-the-point. Loving it.

I just can't believe that you will start this series. I'm expecting a fully functional app after this beginner series. Thanks for quality content

You are AMAZING! They way you teach basics of classes is simply PERFECT!

The best and the simplistic tutorial I have ever come across. Thanks a lot!

My flutter installation was successful, and all the checks passed. Now I can finally follow this tutorial and code 🎉

This is awesome. I believe this should be a standalone dart crash course. Really helpful.

Hey, Shaun! You are already a legendary net-ninja. Thanks for you being around us.

Much Love from Kenya..Its a great Joy to find your tutorials.

Really, that’s the first time ever I really, REALLY understood classes. Thanks a lot

it's kind of beautiful how intuitive this is

For the first time, I understood class completely. Thanks for this free tutorial. :)

Omg.. I've been struggling to understand class in Javascript and php. This is the first time it all make sense. Thanks a lot!

i love the way he is providing all of this for free, when he could actually make us pay for such a quality teching! thankyou so much

Just started to learn Flutter, for a project. Super awesome content ! Top notch in each and every aspect of what a quality content should be. Thanks for the Series, Ninja !!

Very clear tutorial, I will remember how you explain classes and constructor and use it when someone wants to understand those topics

you simplified the class and object topic so smoothly and so easity. great tutorial

In all my years of programming, this 27 min video finally clarified the concepts of classes and objects for me. You're the real Ghost of Tsushima when it comes to programming and explaining things.

i have never seen a teacher like you. thank you. wow wow wow
