Did you know you can hide things behind the dynamic island? This can be used to show easter eggs or your app name behind it that only shows up in screenshots. Super useful for growth hacking or debugging. If you use it, please show me what you used it for!

It's fascinating seeing what dependencies Flutter apps use via Flutter Shark app. Superlist for example uses native_dio_client and http_image_provider which are packages that I wrote. They also use dio and sentry_flutter, which contain a lot of code that I wrote.

I just found another somewhat popular Flutter app in Germany: The Finanzfluss app. It's a tool to analyze your networth, with a focus on stocks. It seems actually rather cool www.finanzfluss.de/copilot/
Finanzfluss Copilot: Portfolio Tracker für dein Vermögen
Verbinde deine Konten & Depots in wenigen Klicks. Analysiere deine Investments & behalte deine Vermögensentwicklung im Blick. Auch als App für iOS und Android!

Did you know that you can track referrer information for your Flutter app, if it was launched via deeplink from a browser?

It can be done with pub.dev/packages/ref...

Huh, apparently we can have custom feeds on Bluesky. Obviously there's Flutter custom feed bsky.app/profile/did:...

It's kinda funny how uCrop has this very memorable design, so that you can immediately tell that the BlueSky Android app uses uCrop for editing images.

I'm currently on my way to Droidcon Italy in Milan. So far
- my train to the airport was delayed
- the stop at the airport was cancelled
- despite that I arrived in time at the airport, however
- the airport temporarily closed the gate and nothing departed, but nobody knows why

I'm hearing from job seekers that it's hard to get a job and I'm hearing from hiring managers that it's hard to find the right talent. Not sure what the takeaway here is

All these discussions about the Flutter architecture guides are kinda amusing to me. It just shows that architecture is way more subjective than we'd like to admit. A good architecture is also adapted to the needs of the app, so such guides are just a starting point.

Today I got approached by a young guy at the train station in my small hometown, because he recognized the Flutter logo on my backpack. He wanted to ask me some questions about a software development apprenticeship. Unfortunately, I had to go but not without giving him my contact details.

I really dig the "domain as username" feature here, but it kinda feels weird having a different handle than on other platforms

TIL that iOS has an extra keyboard type for Twitter. Should we start a petition to rename it to Bluesky?

I've promoted my passkit packages to version 1.0.0. It's now rather complete, functional, stable and I do not expect big API changes.

You'll find them at

- pub.dev/packages/app...
passkit | Dart package
Pure Dart library which can create and read Apple's PkPass files (which are usually shown in Apple Wallet). Works on servers and in apps.
