Starting from Dart v3.11 the workspace definition will support globs! Thanks to Sigurdm for implementing it, it will make our root pubspec files so much cleaner and more reliable. 💙

I love the Flipper Zero so much! 😍
Like today I needed to flash my router and didn't have a USB-UART converter, and of course Flipper Zero covered that use-case, just like it covers a million other weird use-cases I throw at it. It really is the best hackers Swiss army knife!

The current follower count and the Flame logo makes my GitHub profile look pretty metal. 😄

Remember friends; make sure that you and everyone you like adds this to analysis_options.yaml after updating to Dart 3.8.0 so that we make it the de-facto standard, even though it is not default. 😄
I have not heard a single good argument for not preserving the trailing commas.

If this works well, it is revolutionary for Flutter (and iOS) development! Especially for us Linux folks. 😍

Really looking forward to the new Null-aware elements feature that is coming with the next Dart version that is bundled with Flutter!

Quite happy with the Flutter loader in the end of this video.
Thanks to @lohnn.bsky.social for the inspiration!

Have you seen the new Dart static access shorthand feature? It's now in the main branch. 😍
Thanks to @remirousselet.bsky.social for showing it to me.

Are you still doubting Flutter?

Haha apparently a really obscure paper that I was a co-writer of in 2015 is in there too. 😆

A long time since I created a new Effect for Flame, this is the RotateAroundEffect which will be released in the next version.

I finally had time to complete the last puzzle that I had left on #AdventOfCode 2024, great job all the folks that did their best to finish them all on the Dart leaderboard! 😍
Congrats to @hari07.bsky.social that won this year! 🥳

Sometimes you just find these real hidden Dart extensions gems! ✨
Today I found this StreamExtension for parallelism in Melos, which makes it super easy to run a stream in parallel (can easily be used together with isolates too):

`stream.parallel((input) => // Your computation);`

Check out this awesome Flame game that was just released; Idle Horizons (links in the comments)!
I love to see when people build such polished games with Flutter & Flame. 😍

I very rarely take pictures or videos, but I just found this gem on an old harddrive from when I was hitchhiking through Canada a few years ago and decided to try out another mode of transportation. 😅
I have never felt so free in my whole life.

Since transitive dependencies are counted, most of the downloads come from these three packages, but I think dart_mappable will grow a loooot in the near future. Seems like it is becoming the default in many project stacks. 😃

Apparently I'm now top 11 for open source contributions on GitHub in Sweden for this year! It's a real honor being just two positions away from Daniel Stenberg (curl), which undoubtedly is one of the biggest open source profiles in Sweden. 😊

Let's aim for top 10 in 2025!

Dear Santa, please don't give us union types, teach the people how to use Sum types instead. 😅

From Dart v3.7.0, local variables and parameters named _ are non-binding so you can declare them as many times as you want in the same scope without collisions! 😍
Foo(_, this._, super._, void _()) {} main() { var _ = 1; int _ = 2; list.where((_) => true); }
