In classic object-oriented programming, you have regular classes, abstract classes, and interfaces. Of course, Dart has its own take on interfaces, but that's for another tutorial... Somewhere in the shadows though is lurking another kind of an animal. Mixins! What are they for and when should you use them? Let's find out.

I love these dart basics videos ... please do more bruv
I will!
Nice one! Between the two of us we'll probably cover everything in Flutter for developers to build production ready apps 😁
I definitely hope so!
You two are awesome... I learnt 0 to building apps in flutter from both you guys....😁😁

"Now, this is entirely possible, which should not be possible because... it's stupid"
I lost it there. That was just hilarious for some reason. Great tutorials. Great explanations that keep things relevant, to the point, and are easy to follow and understand. Keep up the good work.
I like this teacher, very patient, never tired of explanation.
I love this style of tutorials! Super simple to understand and great use of examples with the occasional hilarious dry commentary. Thank you for taking time to explain so clearly to dart noobs like me and keep up the good work! :)
I'm happy you like this format!
You have a unique talent for keeping the right pace. The quality of content is amazing. I am looking forward to learning more about Dart and Flutter in the coming days and weeks. I am sure your content will be of great help to me in my journey. Thank you very much.
You couldnt have a chose a better example. Really loved the explanation.
You have a great knack for explaining tricky concepts in a simple way - great video
I'm so glad I came across your channel. Very high quality videos, which have been very useful in developing my current Flutter app
Thanks man. Your flutter tutorials are enjoyably clear.
This is nice. For self taught beginner programmers like me who last coded in pascal an eon ago, these videos do come in handy. Please do more of these if you can. The community salutes you.
Thank you sir this got me more clear on classes and mixins.❤❤❤❤
Best 13 minute video ever.
Now finally understood when to usr mixins😌.
All thanx to you man🙏🏻✌
One of the best explanation for mixins!!
Great content! Really helped me grasp the concept of Mixins. The examples were perfect. Keep up the good work!
Awesome!!! I learned a lot about birds! ;-) Really!
Top Notch quality tutorial man. Hat's off to you. I understand every f**king thing.
Makes sense 🙂. Thank you for this very nice tutorial.
Thanks, easy to understand your explanation.
Very nice examples thank you ❤❤❤❤❤❤❤❤
simply fantastic explanations
concise and clear.
fantastic explanation! keep them coming!
Just awesome .
You are awesome, high quality content, thanks!
Great tutorial !
thx clear explanation
But my doubt is we CAN implement too? And do it multiple in case of interfaces. And each class can provide their own implementation with that behaviour method. Then why mixins? I understand the need for composition, other languages do ir too.
Exceptional tutorial! 🥇
Amazing content!
Nice tutorial nice explanation with mixin and on...😍😍😍😍
it's really like the trait in scala
Oh crap! My scoped model pattern with multiple mixins and one AppModule suddenly makes sense!
Thanks Nice work
helpful ❤️
it seems u got good knowledge about birds then flutter 😅
please do more dart andplayslist
Please make a video that explain the factory constructor 🙏
When would you use a mixin instead of an interface? Are they interchangeable? Or is more of a semantics issue? "Mixin is just something the object can do, Interface is a contract, something you know the object will do" ?
you are amazing
Thx for the video. BTW, only female mosquitoes, and only when producing eggs, are the ones that sucks blood.
Great video! What microphone are you using for your videos? The sound quality is amazing!
Thanks! I use Rode NT-1A, most of my previous videos used Auna Mic 900B
11:00 Hi! Just trying to complement here: I think it should be a good moment to say that peck() may have had chirp() as a dependency injection bc not all birds can chirp!
Awesome
Well explained 👍
I'm glad it helped you!
This video is so funny 😂
Nice animal this Swallow thing is. Is it a mamal?
if two mixins have same method name then how can we call the desired method
is mixing used for only methods or they can be used on properties too
I watched a video recently about why OOP is from the devil. And this pretty much demonstrates this. It seems you can do the same functionality in procedural code using just functions without any classes. If you have a fly that needs the functionality of buzzing and a mosquito that needs the same functionality you can just pass them as an argument to a 'buzz' function. And you won't have the luggage of object chains dragging behind you. In this example, you need a class for a fly, a class for a mosquito, an abstract class for flying insects. Not to mention other classes like flying animals that can buzz or whatever else.(I know this is done specifically for this example to illustrate the use of mixins, but those examples do exist in real life) And you need to think about this hierarchy constantly. How come it's not better to have a simple struct that houses the raw data of the fly or bee or whatever you want. Have a simple function 'buzz'. And pass that struct to this function without any classes involved.
Beauuuutiful
Wait a second, Abstract methods can not have a return body how is your can ? ( pls answer I am very confused now )
may I know., what is you theme though?
Thanks for the video. Can a mixin be available to multiple classes? (means multiple classes can be used with "on" keyword ?
Pecking on Bird, AirBorneInsects{ ... }
This is how we need our college to teach us.😅
is it a good idea to make an entity component systems where each component is a mixin?
Hey awesome brother ! anyone from Tenerife and working on flutter or wants to learn how to do it? Hola! Alguien vive en tenerife ?
is it possible for mixin to have an inherited variable? i it in a test in the same file, but i move the mixin in a separate file - it can't see the mixin variable ??
What font are you using in your vscode?
why cant we just do like :-
abstract class Bird extends AirborneInsect {
void chirp() {
print('chirping');
}
}
Reso, no more lessons on Kotlin?
thanks. What software do you use to make these videos (ie. how do you add the swallow pic and the talk bubble)
Premiere Pro for editing and OBS for recording.
I think you forgot to delete void flutter() from abstract class Bird even when it is with Fluttering. There is duplication, right? 09:19
Oh, of course I forgot!
It's called Traits in PHP world!. Mixins = Traits😆 PHP Guys...
The same thing in Groovy
1:44 what a method name! 😂
Mixin = merging
