New post on /r/flutterdev subreddit: Firebase Cloud Messaging - How to effectively use `onBackgroundMessage` callback? I'm fairly new to Flutter and mobile development so maybe some basic knowledge is missing and my question might seem illogical.I am trying to come up with a reasonable way to use `onBackgroundMessage` callback. The documentation states that the callback can be top level function or static method. This means it has no access to members of a class (when using static method) and can basically access other code via global scope.I might have application architecture where I'm passing instances (singletons) to Flutter widgets of services that might do network requests and update application state. Let's say I want to process data push notification while app is in background. Maybe the notification contains some payload, like event name. I do HTTP request with some payload, some data is returned to me and I want to update my application state with the results. To me it's basically not possible as I might already have services for fetching remote data instantiated as classes, for state management I might be using `flutter_bloc` so I need access to `context` to update my "BLoC".I think I get the point that there are limitations in place to abuse bad behaviour. Apps should not be doing stuff in background or maybe very conservatively. I assume that the background process runs in isolate and it's easier to release resources in dart code when it's just a function?How do people process data in background then? You would at least want to store data coming from data push notification somewhere. I can only think of one way. Creating a class that is instantiated via `factory` constructor where I could store such data so it would have its own internal state. With that I could get a reference to my singleton instance inside the callback and call some method. However I am using dependency injection in my code already and creation of singletons is handled in different way. June 02, 2021 at 07:27AM by ondrejsy https://ift.tt/3ifksN5

New post on /r/flutterdev subreddit: Simple app for reading EU Digital COVID certificates in Flutter - WIP Hey,I recently got my certificate for vaccination, but I wasn't able to read the QR code from it. I know that there is an official app in progress, but I wanted to see how difficult it is in Flutter. It took me just few hours, hovewer, it's really basic app right now. It should work on Android and iOS, and I would like to support web as well. If anyone wants to use it or to add translation, feel free to. I want to add verification of the QR code, as well as more informations, but as simple PoC, it works just fine.If anyone wants to learn more about EU certificates: https://ec.europa.eu/health/sites/default/files/ehealth/docs/digital-green-certificates_v1_en.pdfAnd here are some examples of QRs: https://dgc.a-sit.at/ehn/testsuite​And here is my app: https://github.com/lepsi-city/vacito, it's not on Store yet. (and I am not sure if there will be any market for it, after the offical apps get released, which should be in few days.) June 02, 2021 at 05:05AM by pilsen_plex https://ift.tt/3papaNw

New post on /r/flutterdev subreddit: How stable is the flutter web? I read that with flutter 2.0, flutter web has hit the stable milestone. I'm going to be working on a project that primarily runs on mobile apps, but I'll still be needing a website with all functionality. People who have used flutter web, how was your experience with it? What were the major problems you faced and are they any better now? June 01, 2021 at 06:53PM by CaptainFerb https://ift.tt/3uIwlhb

New post on /r/flutterdev subreddit: My first published package: mutable_notifiers It's a small utility piece, but something that I found I needed/wanted in my own projects that I finally decided to pull into its own package.I found myself wishing that I could "turn off" ChangeNotifiers/ValueNotifiers while I updated several things at once, and then just call notifyListeners() once at the end.MutableChangeNotifier and MutableValueNotifier provide that option in a minimal little package. Check it out if you've ever wanted something similar.https://pub.dev/packages/mutable_notifiers June 01, 2021 at 07:02PM by dljens https://ift.tt/3fFiZy7
