Hardware looks scary until you break it down into small steps. So I built an app that takes you through Arduino one circuit at a time.
Made with Opus 5.5

What if your iPhone and Mac were one screen?
Apple never made this, so we're building it
NameDrop, but between your iPhone and your Mac. Fastest and most satisfying way to share files
We might be cooking something crazy here

New review guideline from Apple
developer.apple.com/app-stor…
Things can lead to ban
- Tricking the review process or hiding dormant code
- Buying fake reviews or manipulating chart rankings
- Copying other developers' UI, icons, or brand names
Jev can be Flutter's friend. Try it for your products.
By now you've likely heard of Jev from @typesafeai, but have thought about using it with your #flutterdev tests? @yiichenhi has done a great write-up on the process and the amazing results of using Jev with your tests to keep them green. medium.com/flutter-community…

Mobile Use + Jev for audio = ULTRAFAST⚡️
10x faster and 20x cheaper than Gemini Live.
It's our Audio Action model, Thud.
Thud listens and then does. It has a pre-built list of actions it can take on every page and listens for that action.
It's 2026. We don't need to transcribe every voice command before spoon-feeding it to the AI. The AI is smart enough to just hear audio and do! It doesn't need text.
Do you have fried brain🤯?
AI was supposed to make us work less
I've never been this tired in my life
most days I have up to 10 agents running at the same time. one fixing a bug, one writing pages, one refactoring something I already forgot I asked for, 3 other I have no idea what they are doing but i suppose i ask it?
and I jump from conversation to conversation all day
compared to 5 years ago, I probably context switch 100x more
by the end of the day my brain is fried. completely toasted. nothing left, not even for the people I love
I call it the fried brain effect
thought it was just me but almost every founder I talk to lately says the exact same thing
we got superpowers, and somehow the pressure only went up. if you can ship 10x more, you feel like you have to ship 10x more. every single day
I don't have a solution
honestly I have no idea where this goes from here
anyone else feeling this?

Today, on Google Play we announced new ways we are evolving the Play Store for an experience that is unique to you and the content you enjoy most:
✨ Use Play to wirelessly install and run your own custom, vibe-coded apps privately on your device.
🔍 Discover apps effortlessly with Ask Play & Gemini
🎮 Dial in discovery with the all-new Game Finder & Gamer DNA

Gemini 4 Argon + @FlutterDev is cracked.
@antigravity built this car infotainment screen and driver cluster with Flutter Scene in a day. It's all one Flutter app. :)
The map uses real OpenStreetMap buildings in downtown Boston and a live route from OSRM. The x-ray chassis uses a custom material, and the brake discs glow as the car brakes. The car is a glTF model with working doors, hood, hatch, headlights, and paint options. The parking screen is a mockup of a 360 surround camera view.
No embedded engine, no native map SDK, no platform views, just vanilla Flutter with Impeller and built-in SDK features: Flutter GPU. 3D rendered by Flutter Scene, a complete 3D game engine for Flutter.
The app is 14,000 lines of Dart, with a center screen, a driver cluster, and a panoramic view of both.
No subscriptions, no paid seats, no royalties. Free and open source, forever. Flutter can just do it all.

Reverse engineered my AC, and vibe coded a lil status bar app so I don't have to find the remote every time.
No first world problem will remain unsolved in 2026.

Flutter on Apple Watch is now open to everyone.
Standalone or companion watchOS apps, pure Flutter widgets.
Create. Run. Ship.

iPhone AGI has been achieved 🔥🔥
An agent running entirely on my iPhone, with no computer connected or in the loop at any point, able to control absolutely anything on my iPhone.
✨ iPhone computer use ✨
Everything after the first message is an agent tapping and typing.

ChatGPT launched their version of Generative UI yesterday. We took it apart
tldr; the agent never write raw code. It emits DIL (a new language), the server compiles and streams it, the client renders it using a component set so that it feels native
Yii Chen retweeted
Good news, people! I just published another Flutter and #dartlang benchmark blogpost.
Have you ever wondered if it's faster to do
for (int i = 0; i < list.length; i++) { ... }
or
for (final element in list) { ... }
?
(It's the latter.)

Asked Opus 5.5 to make a video. One prompt, one reference link.
It built the 3D bricks, camera, music, SFX, subs and narration in code. It even listened back to its own voiceover to fix pronunciation.
My first reaction: “Wow"
Style inspired by @victormustar's LEGO video

Opus 5.5 designing LEGO 👀
I asked it to design a Microduck I can build with real LEGO pieces. It:
> designed it life-size using 1113 real LEGO parts
> verified: 3,204 connections, 0 collisions, every step buildable, centre of mass inside the feet 🤯
> made a 141-page LEGO-style booklet (237 steps)
> priced every piece in the browser and prepared the orders on BrickLink
Changed, changing
I am done with this shit. It is over. The state of engineering right now is horrible. It has been half a month since I started a new role at a big company. Nobody knows anything here. The specs, code, tests, PRDs, tickets, resolution of those tickets, reports, etc., everything is made by Claude Code. Nobody on my team likes this. They are being forced to ship as much as they can. I have heard multiple times from higher management that pushing code is not a bottleneck, so why are we slow? People are working 12 to 13 hours a day just to press enter. Nobody is reading anything. Humans in corporate are doing nothing on their own. Everyone, literally everyone, from an L1 to an L7 engineer here is doing the same thing. Talk to Claude. There is no sense of victory. Nobody is resolving bugs. In reality, nobody is thinking anymore. Everything is done by LLMs. It is so soul-sucking. I would not mind it, to be honest, if we were at least given the time to check out the code and see what is going where. But no, the goal is to just ship. No matter what happens.

What if agents could build your game graphics, and you could review every change in a git diff? 🤔
That's what I've been doing with the Rive CLI + RML in Betsy for our #FlutterDev feed mini games. Works much better than I thought it would. Next, taking it to real-time 3D🧵

v incredibly proud of our 2026 Google Summer of Code contributors! We just wrapped our 7th year mentoring for Dart & Flutter and the results are amazing. ✨
Highlights include:
- WebSocket support in DevTools
- C++ compatibility for FFIgen
- Native memory inspection in Dart DevTools
thank you to everyone who makes our OSS community so vibrant and welcoming 💙

Flutter had zero iPhone Duo support. Now it has a package. 🥳
foldable: hinge angle, fold posture, crease geometry and size classes, straight from iOS 27.1 to Dart. Safe on every non-foldable device too.

It doesn’t matter how good an AI model is if it can’t test its work quickly and reliably. That’s especially hard on mobile.
Traditional approaches rely on screenshots or the accessibility tree, making feedback slow and brittle. Agents can change code in seconds, then spend minutes trying to test it.
In our new mobile apps, business logic runs headlessly. Agents can inspect state, navigate, and act through a CLI in milliseconds, without a simulator. When they need to test the app, the same CLI drives the simulator directly.
The video is real time.
