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 flutter.dev/wasm 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.

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. 😎github.com/flutter/flutter/c…

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!

DartPad is now running with #Wasm (if you're on a Chromium browser) dartpad.dev/?sample=sunflowe… It's actually a cool hybrid: the host app is wasm, but we still use JS for the user-compiled code. (Also the updated Sunflower demo is so cool!)

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...

Read the thread for the link. An impressive effort. Already shared with engineers on the Dart team. We're digging in her a LOT. This is great inspiration!
📣 I just published an RFC for a new Serialization Protocol for Dart.
Its the outcome of over three years working on dart_mappable, lots of feedback from devs and lots of research.
I've made a Flutter Forum post about it. Please give it a read and let me know your feedback. 👇
