I had the AI write a quick little tool to batch-generate images (house.png, tree.png, etc.), and it’s surprisingly handy for jumpstarting new projects. Any failed ones can just be regenerated. Should I publish it, or is it too basic?

Looking for something dead simple like this. A pluggable system to prompt the user for actions, such as rating, subscription, feature wishes, virality pushes. Ideally with some guards to prevent double calls. Is there a package for that, or should I cobble something together? #FlutterDev

When AI gets the coding job done, it’s great. When it doesn’t, you’ve wasted time and money and learned nothing in the process....

I love me some aliases to speed up my workflow 🚀 >podfix comes in handy quite often for those pesky "The sandbox is not in sync with the Podfile.lock..." errors. 👀

New Vibe Cook update 🍳🌈 Turned the favorites section into a full history. Now there’s just a little toggle for favorites. Also, a few people asked if the AI recipes are actually good. I’ve cooked a few and was genuinely happy with them. Though, I mostly use it for recipe inspiration.

Just dealt with another round of missing analytics events using go_router and NavigationObservers, I decided to write down a quick list of fixes. 🫡 Nothing too complicated, but I forget them every damn time. christopher-marx.de/blog/go_router_…

No, you can't just add FirebaseAnalyticsObserver and be done with it

Reworked the onboarding on my new project. Quite happy with it.

I will forever hate CORS. 😩 And I am still torn on AI generated code. On the one hand it generated a working CORS preflight middleware for my #dartfrog backend. ....on the other hand it had an edge case bug that cost me roundabout 2 hours to find.

I write a lot of empty function stubs for later use, and my new way of abusing #dart, is using @Deprecated instead of TODO, so I get a lint warning when I accidentally try to call unfinished code. 🥸

Funny. I just encountered this bug in a menu app of a cafe: github.com/flutter/flut... Anyone who operates a Flutter web app should update to Flutter 3.27.1 otherwise users on newer iOS Versions can't scroll. (Unless users are Flutter devs and try scrolling with 2 fingers 🤡)

Is there a service like featurebase, where users can suggest and vote on new features for #flutter apps? @verry.flutter.community and I were talking about it and afaik there are only web implementations. I know there are some good feedback tools like wiredash, but nothing like the above.

Starting to plan my #flutterdev year 2025. I will definitely go to Fluttercon Europe & Flutter and Friends. Any other events I can't miss?

Touching a #Flutter project from the past using Hive. Good old times :)

Anyone using Make, Zapier, n8n and other quick automation tools? Or are you guys writing up your own automations because you can code?

#flutterdev life is way better when you embrace slivers from the start. I end up rewriting too many ListViews, too often....

I am dealing with a dart project that has to deal with a lot of different paths and expected error states. A functional approach seems to makes sense for me here. Time to swallow the functional programming pill. 💊

Hey #flutterdev people, add more sauce to new widgets entering the screen. 🥫 It's easy. Code: gist.github.com/ChrisMarxDev...

I am at a point where I put anything I type out more than once in my terminal aliases. E.g. alias flbuild="flutter pub get && flutter pub run build_runner build --delete-conflicting-outputs" alias podfix='cd ios && rm -f Podfile.lock && pod install --repo-update && cd ..'

I really enjoy dart_frog with Cloud run. After the initial setup, I now have a quick way to whip up any small backend services that I might need in my side projects. And cloud run is still really cheap.

Whenever I spot code like this in a client project, it puts a smile on my face. It’s so easy to add a small transition animation and make the project look just a little bit nicer.
