I'm guessing I'm not the only one who went from "Which Tesla will I buy?" to "My next car could be one of many EV brands – except Tesla" in a shockingly brief amount of time.

Hey folks! Kevin, product manager on Flutter and Dart here.
The layoffs were decided AT LEAST a couple of layers above our team and affected a LOT of teams. (I think I can say that). Lots of good folks got bad news and lots of great projects lost people.

If you haven't checkout for a couple of weeks, now is a good time. As of ~today, Flutter @ master can now compile (preview) Wasm that supports Firefox (Nightly).

We're sad, but still cranking on hard on I/O and beyond.
We know ya'll care SO MUCH about the project and the team and the awesome ecosystem we've built together.
You're nervous. I get it. We get it.
You're betting on Flutter and Dart.
So am I. So is Google.

See this BEAUTIFUL native application? It's not "native". It's a

#DidYouKnow
every release of

has passed ALL of the tests for EVERY product that uses these technologies at Google? It's sometimes gnarly for us, but it means external users of stable releases get that much higher quality.

@dart_lang
gift! I just release a v1 beta of package:googleapis – – 26 new APIs! I would *love* folks to kick the tires here. Especially for APIs that do file upload/download (think drive, storage, etc). Let me know if you have any problems!

Flutter and Dart were not affected any more or less that others. It was a tough day...tough week.
It was crazy to be seeing demos and new things working and discussions about new customers the same day we lost colleagues and friends.

On native (Dart) platforms 1 (int) != 1.0 (double). But they are identical in JavaScript (there is only one numeric type). We *used* to use this "quirk" to detect if Flutter was running in a browser. Not any more. 😎

Friendly reminder: while
@dart_lang
is amazing language for building beautiful UIs with
@FlutterDev
, it's also the language used for all of the dev-time tooling (analyzer, formatter, dev tools, JS compilers, language front-end) and services (, dartpad). 😎

Re
#FlutterFUD
- from my (awesome) boss.
With so much misinformation circulating about Dart & Flutter I feel a need to clarify. Facts:
- No strategy changes.
- No change in team size; some DevOps roles moving to new locations.
- 2024 roadmap continues.
Now I'll get back to the product!

I'm guessing 98% of Flutter Web users would gladly have this fix – and would like to know the current workaround. But I figured I'd fish for 👍❤️ reactions anyway. (FYI: reactions to are ALWAYS prefered over "me, too!" comments)

Hey Flutter web users: try out form auto fill with the latest release! Also, just try publishing a web app and look at the URL in the browser. Let us know if you see something different!
Flutter 3.13 is here! 🥳
The release includes:
🦋 Performance improvements for Impeller on iOS
🖇️ Deeper browser integrations
🌐 Accessibility enhancements for Flutter on the web
Plus many bug fixes! 🪲

FYI Flutter ecosystem folks (or any OSS ecosystem folks). Check out
@spydon
here. He's SUPER clear about how critical the issue is, but he's also SUPER polite, avoids any finger pointing and quickly replies with details to help us dig in. Be like Lukas!
Any Flutter app with animations currently have a severe performance degradation in both Firefox and Safari (games are barely playable) due to a bug that has been known for 5 months. A cherry-pick with a fix was proposed, but denied due to being too large...

The new package:web is pretty crazy. We use Dart code + JS code (NPM modules), compiled to JS to generate Dart code (pkg:web /lib contents) that we then compile to JS (and WebAssembly).

Just had a deep dive on the future of dart2wasm (and, by extension, Flutter Web Wasm) + dart:html (and friends) + Dart-JS-interop + new Dart language features. 😳
It's like building a bridge.
No bridge: stable.
Completed bridge: stable
Building the bridge: careful balancing act.

Are you writing Dart code that generates Dart code? If you're NOT using, pkg:build (and friends) let me know! I talked to someone today and was super sad that they built their own file watcher and everything. We have TOOLs for this.

I can't WAIT to have an excuse to use Dart Record and Switch expressions like this: – SO COOL!
And it's statically enforced! The analyzer will yell if you miss a case. It's magic!

The engineers have been working so hard since the last major release of Flutter. So glad you're seeing these results!
Thanks for the outstanding work on the fixes
@yegorjbanov

Afternoon pondering/question: – Listenable, ValueListenable, ChangeNotifier and ValueNotifier – why not others? I could imagine wanting to share Dart code beyond flutter that uses things like Color, Rect, Size, Offset. Any others?
