I am speechless. Thanks to the @FlutterDev and @firebase teams for supporting me and patiently listening to my inputs. We did this together 🚀
Congrats to Flutter #GDE @ulusoyapps on the dev keynote shoutout! 👏
Great to hear a Flutter and Firebase app mentioned on the #GoogleCloudNext stage.

After Turkey's February 2023 earthquakes relocated local businesses to container markets, finding essential services became difficult.
A volunteer team paired Flutter, Riverpod, and @Firebase to build @hatayiyasat with live directory maps and alerts → goo.gle/4yysrsZ
ALT Two smartphones display the Hatay'ı Yaşat app: a dark patterned welcome screen with a red button and a bright sign-in page, conveying a polished, modern tone.

Pro subs, here you go! Give Argon a try.
We’re rolling out Gemini 4 Argon in Antigravity to paid Google AI Pro subscribers today. Demand has been incredible and we've scaled capacity deliberately to get here. We’ve rolled out a separate weekly-only Argon quota for Pro on top of the existing Gemini bucket for 3.8 Flash so you have the best of Gemini for all your tasks.

I have no dog, but I feel like I should install the app and just take myself out for walks and build my #vikkeland and just call it #mikkeland 😂 If you walk a dog regularly, go check this out - pretty darn cool 😃
Just generated this promo video for #vikkeland with Gemini #argon and I've to admit it's funny 😅 👇 👇 👇

I asked Codex to roast my app’s feature screen using a design plugin. It proposed a redesign, then let me add comments directly to the mockup and request changes, just like in Figma. What a time to be a solo indie developer!

Cagatay implemented an animated app theme switcher with Gemini 4 Argon in just a few minutes.

I have been testing Gemini 4 Argon in my @FlutterDev Finish it project using @antigravity. Here is my showcase:
I loved @_Kavsoft’s theme switcher interaction with SwiftUI, so I gave it a Finnish Lapland twist with Aurora theme in Flutter 🇫🇮❄️ All rendered in a single custom canvas.
Implemented with Argon, only in couple of minutes.

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.

It's incredible to see what our community is already creating with Gemini 4!
Here is the Lapland reference poster I dropped into the prompt to guide Gemini 4 Argon 🇫🇮👇
Zero image assets in the final build. Gemini broke down the color palette, the layered snowdrifts, the cabin perspective, and the aurora curtains into cached Path geometry and hardware radial shaders in Flutter.
I love how the @antigravity previews embedded in the chat. It is interactive, and gives a great visual insight among alternatives before implementation.
However, although being embedded in chat is good, it should also be possible to view it in a separate window full screen to interact because scrolling up down within the frame is not helping for evaluation. @peterfriese

I missed Mehmet Ali’s talk at @FlutterconWorld but cant wait for the recording. Vibe once, run everywhere 💙
Why rebuild your Flutter app's design in SwiftUI just to put it on a watch?
With flutter-watchos the watch app is Flutter too. One codebase, and live state sync over WatchConnectivity.
Apple Watch was the last place Flutter couldn't go.
