@jezell @dersimolus We can't switch to these by default because these are not supported by oldest supporter browser versions.
We could do it under a flag though.
English
@mraleph @dersimolus Ah, @dersimolus's fork appears to be a bit behind, will make a custom 3.13 fork because the new standalone mode is great. Really would be nice to get a fix merged for this though @mraleph, it's probably going to prevent standalone mode from being very useful.

Having to downgrade wasmtime because dart WASM exception handling still ships legacy exception behavior that got deprecated over a year ago is lame @mraleph.

I am having FOMO - great lineup!
I had to skip this year - but dont repeat my mistake and grab your ticket!
Flutter & Friends@FlutterNFriends
We're proud to present the full speaker lineup! 📢 Hybrid AI, Flutter Desktop, Accessibility for 1M users, GenUI, Marionette MCP, 3D, Enterprise Architecture, Monetisation... these are just a few topics of our diverse agenda! 🤯 Full list and tickets 👉 flutterfriends.dev

Is this the first Flutter implementation running on top of Skia Graphite + WebGPU? Sometimes if you want it done, you just have to do it yourself... or ask Codex to do it for you.

@birjuvachhani Dart uses V8's regex engine with JIT disabled (because we can't JIT on iOS so that makes regexp perform the same way on all platforms). We could theoretically enable JITing on platforms where it is supported.
English
Did you know that Dart Regex compiled for web is 6x faster than compiled for Dart VM?
I was porting Oniguruma C lib(regex engine vscode uses for tokenization on TextMate grammer parsing) to Dart and did a benchmark on few things!
Learning a lot about Regex implementations!

@KrTirtho @alexmercerind In the last year build_runner performance should have improved by significant margin. Are you still seeing 5+ minute rebuilds? Then file bugs and ask @__davidmorgan__ to look at it.
English
@alexmercerind Agreed. And Dart team are still unable to solve code generation.
In 2026, waiting for build_runner to compile for 5-10 minutes is honestly an experience kinda unacceptable.

@mahersafadii That's not what you think it is. There is no agreement to add full shared memory yet. (As in sharing mutable dart state between concurrent threads of execution). This is a set of features bridging some of the gaps between threads and isolates without removing isolation altogether

Looks like shared memory multi-threading coming to Dart is really soon, only 11 issues are open out of 40 regarding the implementation of it github.com/orgs/dart-lang…

Few unplanned free evenings in Sofia. Anybody I know who wants to meet for a beer?

@ASalvadorini @RydMike > Sure but it's not gonna happen. The Dart team already stated it many times.
I don't think we actually did state that anywhere. Appeal of such feature (e.g. automatic synthesis of hashCode, equals, toString) is pretty clear.
English
@RydMike Sure but it's not gonna happen. The Dart team already stated it many times. The community doesn't own the code, they do and they know better.
IMHO it's a very stupid attitude when devs talk about Dart badly because it doesn't have data classes 🤷♂️
English
All true, well argued and nice, BUT I’ll play the other side. Having data classes in the core lang like in Kotlin and Swift is nicer, then everyone uses that, making code bases more consistent, agents knows it better, no arguments about which approach to use #DartLang #FlutterDev
Alessio Salvadorini 💙@ASalvadorini
So let's once and for all have a small thread about data classes in Dart, a feature the community requests often. My point here is that they are not needed to be at the language level, as you can have immutability already in many different ways + sealed classes 🧵⬇️⬇️⬇️

i was reading the SQLite source
and found that DELETE does not actually shrink the database file
deleted pages are placed onto an internal freelist inside the file
new inserts reuse those free pages before growing the database again
the file itself only gets smaller when you run VACUUM
delete everything from a 1GB database and the file is still 1GB until you compact it
English
@TrisH0x2A @vedr4j do you have a link or full font name?
cause the only nova font I can find looks nothing like this.
English
@felixge I was assuming that ping would happen on the CL - I don't see any there.
Next step after that is to assign a different owner :)
English
@mraleph No response, which is why I'm casting a wider net 🙈.

If anybody with connections to the V8/Chrome team is reading this, my colleague Attila is trying to find a reviewer for a patch to improving profiling.
Many thanks in advance for any leads 🙇🏻♂️

Мои дети научились кататься на двухколёсном велосипеде в пять лет. Всё потому что у них была неэффективная траектория обучения: сначала трёхколёсный велосипед с приводом к переднему колесу, затем велосипед со страховочными колёсами, и только потом, когда казалось, что они уверенно крутят педали, страховочные колёса я откручивал и учил кататься без них. Собственно, этот путь я запомнил с моего детства и его придерживался.
Сегодня бегал наперегонки с трехлетней девочкой (ну ладно, ей уже скоро четыре), которая весьма уверенно педалит на двухколёсном велике. Спросил родителей — конечно же она начинала с беговела ещё в два года. Страховочные колёса ей и не потребовались. Много таких историй.
Не повторяйте моих ошибок, в общем. Беговел — тема. Мне казалось, что это странная и ненужная штука, но я был неправ.

"initialization-order-fiasco" – are you trying to embarrass me, AddressSanitizer?
English
@tagir_valeev Частая проблема ещё в том что детские велосипеды ужасно тяжелые. Бывают 14-16 кг. Для ребенка который и 25 не весит это гигантские нагрузки, легкий фанерный или алюминиевый беговел лучше.
И велосипед потом нужен легкий. Лучше меньше трети веса ребенка. Есть хороший рынок б/у.

@ASalvadorini @AymenMak84548 I think most of the stuff in the linked issue has landed under experimental flag and we are in discussion to remove the flag...
though I am not sure how it helps in this particular case.
English
@AymenMak84548 @mraleph do you have any estimated timeline for that to land? 🙏😇☝️☝️☝️

Dart must easily be the most versatile computer language out there. 🎯 * Runs as a scripting language (like Python) * Compiles to kernel code (like Java’s bytecode) * Compiles to native code (like Swift) * Compiles to JavaScript (like TypeScript) * Compiles to WASM (unlike TypeScript) * Has sound null safety (like Rust) * Stateful hot reload (like no one else - Erlang maybe?) * Runs on virtually any platform (like C/C++) In addition: * Has great developer tooling * Interops easily with other languages * Has an outstanding UI framework (Flutter) * Nicely mixes with native UI components * Is really easy to learn and work with Today, I learned that the full compiler, analyzer, and tooling can even run on a web page. Mind blown. 🤯 What else did I miss?
