Sorry, I don't know what you mean by vibration patterns right now

Our talk on Physicality in UX has been uploaded to YouTube! If you want to learn how to build physically driven interfaces in #FlutterDev check it out! If you just want to learn about motor and why you should use it, skip to 19:00 🏎️

liquid_glass_renderer is still progressing nicely! This is entirely rendered in #Flutter at 2.2ms/frame, no overheating or frame drops. It's still not ready for production, maybe I'll never call it that, but it's definitely cool to push what's possible :) Physics by motor btw!

Tim @i.madethese.works · 01/10/2025

By the way, motor 1.0 is out! I'll be sharing more here soon once my FlutterCon talk is uploaded. We cooked up a bunch of cool examples and visualizations to show why motor is the best choice for orchestrating your #Flutter animations right now

Is there any info on that engine you're working on somewhere? I was really looking forward to see what you came up with Well at least I won't have to be sad to miss one of the Toyota talks since we were speaking at the same time 🥲

Tim @i.madethese.works · 22/09/2025

NOOOO what? It was at the top of my list this year 😭 Is Joel also not speaking? Hope everything is fine!

I'm gonna post some of the stuff I've been posting on Twitter in the meantime, but please only repost what you would actually want to yourself 😅 But if you know of any experienced graphics programmers that could help me optimize my liquid glass shader let me know 👀

Tim @i.madethese.works · 22/09/2025

Okaayyy I'm gonna try to come back here! Don't tell @kerberjg.bsky.social that it's basically just for her posts 🌝

We might have the coolest #FlutterDev counter app 🤭

Tim @i.madethese.works · 15/04/2025

Also cute for loading spinners! (I'm tired of the same material spinner everywhere anyway 😅) #FlutterDev

Tim @i.madethese.works · 15/04/2025

Not yet, sorryy 😬 It's gonna be at one point, I promise! It's still a mess though (this is running on Mac as an external display right now, because shader compilation to metal is finnicky as hell 🙄)

Tim @i.madethese.works · 14/04/2025

#FlutterDev shaders and hand drawing are a super fun combination! Check out this y2k liquid metal shader ⛓️

The Springster Example website now lets you select the motion for most of the examples! This is a great way to feel the advantages of simulations in #FlutterDev yourself. Check them out here: whynotmake-it.github.io/rivership/#/... Can't wait for this prerelease to drop pub.dev/packages/spr...

Tim @i.madethese.works · 10/04/2025

To be fair, it's quite niche 😅 I had to verify it myself because I also wasn't entirely sure, but this test only passes with the .then implementation:

230

Tim @i.madethese.works · 10/04/2025

Bonus challenge then: What‘s an advantage of the former implementation?

110

Tim @i.madethese.works · 10/04/2025

okay, I'll come up with a harder one next time 🙄 😉

Tim @i.madethese.works · 10/04/2025

Another #FlutterDev quiz: There is a subtle difference between these two implementations. Which one of them is more robust and why?

240

Tim @i.madethese.works · 09/04/2025

Niche flutter question: is there any way to force flutter not to bundle the assets from a certain package (at build time based on environment var) Tree shaking the packages code is fine, but assets not so much #flutterdev

120

Tim @i.madethese.works · 03/04/2025

Not a single AI that I tested could solve this

Tim @i.madethese.works · 03/04/2025

#FlutterDev challenge: Fade between two widgets, but never let anything behind them show, provided both had full opacity. Parts that have 0.5 opacity in both should have 0.5 in the result. Conceptually, each pixel should interpolate its color values between the widgets.

Tim @i.madethese.works · 02/04/2025

I believe package:heroine is shaping up to be one of the best ways to build fullscreen Container Transform transitions. I wanna refine it some more, so it's a prerelease for now, but check it out! pub.dev/packages/her... #FlutterDev

Tim @i.madethese.works · 25/03/2025

One of the fun learnings from understanding the inner workings of AnimationController for the next springster update: Everything is represented as simulations internally, classic #FlutterDev animations are really just physics simulations that don't use the initial velocity

Astronaut Meme.
Astronaut 1: "Wait, it's all physics simulations?"
Astronaut 2 with the gun: "Always has been"

pub.dev/packages/spr... This might also be a nice baseline for the discussion on how to introduce springs to Flutter here: github.com/flutter/flut...

I just published an experimental update to the springster package and I would love some feedback on the API! The main goal is to support more than just spring simulations. I've tried to write it up nicely in the docs, but I'm not the best at it, so let me know if you see any issues ✨ #FlutterDev

My animated_to package now introduces “spring simulation” version of AnimatedTo widget, AnimatedTo.spring()! This enables physics-based animation when child updates its position, which means so smooth and natural! Try this by importing the latest version of 0.3.1! pub.dev/packages/ani... #FlutterDev

Tim @i.madethese.works · 26/01/2025

Fun fact: Heroine can also be used to very easily build high fidelity page transitions, similar to what material calls "Container Transform", including Gesture support! I'm planning to expand on that capability even further in the future, to make it more useful and customizable. #flutterdev

Es ist definitiv keine Wahl in der ich eine Splitterpartei wählen würde 🫣

Tim @i.madethese.works · 23/01/2025

Responded on the forum in more detail, but I've really been getting into spring simulations as a replacement for duration & curves (I've been talking about nothing else on here basically) Would love to see that in the framework at somepoint and would be glad to contribute!

010

Tim @i.madethese.works · 22/01/2025

I built a spring-simulated POC of the amazing animated_to #FlutterDev package by @chooyan.bsky.social today. Some things need to be ironed out still, but it took me 15 minutes to build using package:springster and works great already! PR: github.com/chooyan-eng/...

Tim @i.madethese.works · 22/01/2025

oh and #FlutterDev 👆 (I wish the Flutter News feed was smarter)

000

Tim @i.madethese.works · 22/01/2025

Also: if you used heroine in widget tests, you might have noticed that it didn't always dispose its Tickers correctly. That's fixed too! We also have around 60 x the test coverage from before 😅

Tim @i.madethese.works · 22/01/2025

✨ Heroine Update ✨ heroine 0.3.0 is here: pub.dev/packages/her... ⛓️ You can now chain ShuttleBuilders for more complex animations – see the video for a combined flip + fade animation 💍 Less jank: in a few cases a bouncy spring would jump a little upon landing – now it's buttery smooth

230

Tim @i.madethese.works · 22/01/2025

@tahatesser.com was right – golden tests using AnimationSheetBuilder are super fun! More transitions and higher fidelity coming to package:heroine soon btw 👀 #FlutterDev

Tim @i.madethese.works · 22/01/2025

It seems like a #flutterdev Widget can't reliably access, wether the route that it's in can be popped (see PopScope). ModalRoute.of(context) doesn't notify listeners when its popDisposition changes 🤷 Thus, I can't disable the dismiss gestures in Heroine when a route doesn't want to be popped...

Tim @i.madethese.works · 19/01/2025

Excited about this, I‘ve been wanting to look into it for Automotive prototyping, but haven’t gotten around to it!

120

Tim @i.madethese.works · 14/01/2025

Please stay! More people need to just commit a bit I think, and I wish we had some of your posts on here to drive discussions

020

Tim @i.madethese.works · 13/01/2025

I just read through the code for the first time, and you’re a genius for doing this in the paint phase. Absolutely brilliant solution, I feel like it‘s been hiding in plain sight 🤯 It should be quite straightforward to add spring simulations to this, I‘ll open an issue to discuss it!

Tim @i.madethese.works · 13/01/2025

If you‘ve ever wondered why your Flutter App feels sort of muddy and different on iOS, I bet this is a huge factor

I check this #FlutterDev issue probably once a week… I‘ve contributed to the Framework before, but I have zero engine XP so I haven‘t dared to take a stab at it. Whoever fixes this is gonna be my absolute hero(ine)! github.com/flutter/flut...

I can't even count how many times I've had to copy entire files from the framework into my codebase, because a class wasn't public... I agree, there should be more escape hatches

Tim @i.madethese.works · 13/01/2025

I‘ve always used package:sheet by @jaimeblasco.com for this, but when I saw the new Route Transition API in 3.27, my first thought was that now someone‘s gonna build this into Flutter. So so looking forward to this, it‘s been missing for so long!

The timing! I was just thinking about how to write golden tests for the spring packages. Thanks a bunch 🙌

I also like the fact that it’s not run by a billionaire megalomaniac that can use it to influence public opinion for his own benefit 🫥

If I started porting #FlutterDev implicitly animated widgets over to spring simulations as part of springster, which ones would you like to see first? (anything that starts with Animated)
