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

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 😅

Why?

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/

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 :|

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

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

Darf ich mich damit dann höchst offiziell als "Prompt Engineer" betiteln?

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

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

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

01.12.2024 15:22 👍 1 🔁 1 💬 1 📌 0

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).

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())

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())

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...
