The watermark is shown when screenshots are sent by users, thus recipients can easily search for the app

Jonas Uekötter @uekoetter.dev · 07/07/2025

True, but the element is also not meant to be seen or interacted with during app usage. It's only meant to be seen on screenshots 😅

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!

Shouldn't it default to `numberOfProcessors - 1` since one isolate is the one running and thus can't be used for other computations?

New Flutter hotfix just dropped

Virtually every app also depends on the *_plus packages and a surprising amount of apps also doesn't have any kind of error monitoring integrated. That's kinda wild to me.

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.

The current indicator for an app using Flutter is that it's not 120hz on my Nothing phone ☹️

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.de

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!

I'm personally a huge fan of 69 or 420

Yeah, I assume creating those passes should work. But as said, since I don't have access to the hardware, I'm unable to test it :|

Jonas Uekötter @uekoetter.dev · 05/12/2024

If you try it, I would love to know whether it works or otherwise help you figure out the issues.

Jonas Uekötter @uekoetter.dev · 05/12/2024

Creating NFC should work. The new iOS 18 NFC passes are not supported since Apple hasn't released any documentation about them. I haven't tested NFC passes though since I don't have hardware to do so

That's super interesting to see

Yes, I'll still be working with Flutter. Although I wouldn't mind doing (a bit more) native development

Yesss, the next gig is already lined up. Stay tuned for the announcement next week or so haha

After 3 years of working at MediaMarktSaturn, Europe's largest electronics retailer, this month will be my last at the company. It's time for new challenges next year.

You will not get any information. Yeah, it's super annoying

020

Jonas Uekötter @uekoetter.dev · 01/12/2024

In the end this allows you to know from where your users are coming, not just which deeplinks they like to open the most

111

Jonas Uekötter @uekoetter.dev · 01/12/2024

That's a different thing. The code snippet is not about retrieving the deeplink, but the referrer link. So e.g. if you open "example[.]com" in your app from a Google search, you'll get a link to the Google search page (aka what the browser sets as referrer).

111

Jonas Uekötter @uekoetter.dev · 01/12/2024

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...

class ReferrerObserver with WidgetsBindingObserver {

@override
Future<bool> didPushRouteInformation(RouteInformation routeInformation) async {
final referrerInfo = await Referrer().getReferrer();
// TODO: Track the data from referrerInfo
return false;
}
}

// Add the observer somewhere
WidgetsBinding.addObserver(ReferrerObserver())

There's also another one bsky.app/profile/did:... but it doesn't really work out. People apparently want to call tweets on this site flutters?

Jonas Uekötter @uekoetter.dev · 30/11/2024

You should try resting on a work day

Jonas Uekötter @uekoetter.dev · 30/11/2024

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

Sometimes I feel like colds and other health issues always creep up on you as soon as you get some rest

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. github.com/Yalantis/uCrop

Surprisingly, I actually arrived on time in Italy. I still don't understand how that worked out, but I'm happy it did

Jonas Uekötter @uekoetter.dev · 28/11/2024

What have I done to deserve this curse? 😭

The story goes on! I've gone through the boarding check, but the doors of the airport won't open, so we can't get out of the airport into the plane.

Jonas Uekötter @uekoetter.dev · 28/11/2024

But somehow I'm still on time?!

Jonas Uekötter @uekoetter.dev · 28/11/2024

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

Jonas Uekötter @uekoetter.dev · 26/11/2024

At the same time experienced devs are unlikely to switch because it also got harder for them. So their supply is declining

020

Jonas Uekötter @uekoetter.dev · 26/11/2024

I don't think it's a tooling problem. Maybe it's more of a supply/demand thing. Companies want experienced devs due to the harsher economic, but due to the ZIRP era there are huge amounts of early career devs that got promised easy jobs? I'm just guessing here tho

220

Jonas Uekötter @uekoetter.dev · 26/11/2024

That's probably on a company checklist: experienced dev = 5 years of experience in technology x. And then they didn't bother to look up how old that technology is
