Freezed (Package of the Week) 

Code generation in dart is janky and terrible. It's not the same as language features.

yeah, even the fact that they announced Freezed as Package of the Week it is not even funny. There shouldn't be such package for "modern language" as Dart at the first place

Sometimes code generation takes too much time

Code gen is fully headache

I have worked on some projects using freezed as suggested by my team colleague and i found it really pain while dealing with states between immutable freezed classes and what i like about freezed is it's saves us from running into bugs by showing errors in line editing thats all rest is so tiring and complex work and a lot of generated codes with multiole files and 80% of those generated codes are not even used most of the time ahh its really terrible experience fr me and its not flexible you have to use .copyWith or create new var and assign the freezed values to the new then only you can modify the values really pain .

the answer is reflection but flutter will never support that

Totally agreed. Sad to see that instead offering stable solutions Google team offers such ugly unprofessional hacks

@@giorgospapadakis7613 may I ask why it will never happen?

Couldn't say more accurate, man. Long story of using codegen in Java tough me that it's not the thing you want to have around in any environment.

@@giorgospapadakis7613 what’s reflection? Noob here. I could just Google on it. Then reflect on it. Nah I think I know what it is but curious the benefits on this

Indeed amazing time saving tool.

Good to know, I'll give it a try

Way better idea

I have the tutorial video in my channel

Thanks! I don't know how I could have missed such an extension.. It even works with Equatable package.

i have the same thing in mind.

Try its Out Its Also Provide Unions

@@dolbysoundsofficial9323 wow. Cool.

@@dolbysoundsofficial9323 Unions? does thst mean equality? like the Equatable package?

You're just listing your variables and add a few self-explanatory annotations. Not a lot of boilerplate in my book.

I personally use Freezed a lot and I can say that its nothing compared to the benefits it provides

@@vaibhavdangayachvd I also don't know what alternatives they are talking about other than not using Flutter at all 😅

Kotlin data class is so simple. Coming from Android, this seems too much to learn for a simple data class.

@@abhimanyu.n14 Dart feels like I was pushed back to Java . I miss Kotlin so much

Remi's Work is Great ✌️

Remi is a living legend. He inspires me.

The damn problem is that he doesn't get a penny from any of thise

Does that exist?

me too pal

@@michasengotta2295 Data class Extension

That's the best solution. You don't wait build runner everytime. İt's time saver

What it your class changes?

Could you please share the link?

@@kirill4531 similar extension is available for VS Code too if that's your preferred IDE

@@sampathnarayanan3229 do you happen to know if something similar is available for Android Studio?

@@kirill4531 Dart Data Class

Still a fair criticism, it's ok just wanting data classes

You can issue this command only once `flutter packages pub run build_runner watch` and it will watch for changes in generation files and rebuild everything upon every save.

Why can you not use 'extends' with it though?

@@michasengotta2295 I am not sure of why, but it clearly says in the documentation of freezed that it does not support inheritance. I also tried it anyways and it results in a lot of errors. Not sure of what caused this, since I don't know that much about the implementation details of freezed, but it is a thing.

@@wish8047 ok that sucks. Thanks for the heads up, I was about to use it, but now I'm not so sure..

Ça sera compliqué de l'utiliser avec hive je crois

No, it also adds sealed classes and unions, which are extremely powerful and yet to be added natively to dart

YAHH ITS LIFE SAVING ...!!

This is called a "redirecting constructor", and it means that all of the relevant implementation can be found within the class that appears on the RHS. In Freezed's case, this entire class definition is part of the code Freezed will generate for us :)

Had no idea Dart supported reflection!

Why that emoji??

@@hamzabarry7880 cuz its freezed and I like it) nothing more. :)

This is a crutch for absent reflection.

@@koldoon3279 that confused me more than i was before lol

I don't see any mention of this in Freezed's docs. While not exactly the same, you can always use `myObj.copyWith()` to set the "late" value, or you can use @unfreezed to use mutable classes instead.

I have no fn idea why they didn't use Kotlin as the default. It was sitting there ready to go. Already used on Android. Can't think of a single bennifit of selecting Dart over Kotlin. I wonder whose pet project Dart was?

Are you high? Rewriting 10 probably 20000 lines of code in a completely different language Also how much more do you want of that JVM? Its hard to debug, super slow & has huge memory consumption If a hybrid large framework flutter directly runs on this, it will just gonna ruin the native performance of flutter

If it used Python that would be awesome, but it would probably be too slow

Please stop, dart is perfect

Use Dart Data Class Generator VS code extension to get rid of this package and headache. There is a video about the extension in my channel.

why?

@@keithbacalso9433 Boilerplate, heavy maintenance, hard to replace etc

why?

It is not that new. Anyway, we could get nice DSL written in Dart, but got hardcore general purpose OOP hell.

That would require refection which would make tree-shaking and small binaries impossible.

@@francisgeorge7639 true but this things need to consider before even they release dart from day one. I think dart introduce lots of issues including multithreading and isolate even if it is fairly new language. Look at kotlin, how beautiful language is data class,coroutine etc P.S just saying

I've seen people argue that dart's flutter version (native dart has reflection) makes sense for front facing code. Seeing people complain of the web load speed could be argued either way: even with no reflection they couldn't get it small enough, or that it's still good enough as a web app even if too large for a web site.

@@francisgeorge7639 Bullshit. Lots of other languages and platforms solved this problem somehow and dart team also can, but this decision looks rather like some conflict with their ideology - I can't find another explanation.

@@koldoon3279 Why would I bullshit you? That's the explanation they have given themselves. And it makes sense to me.

It was that or "Let it goooo"

@@remirousselet6867 Let it go it is then! Better than a typo...
