Is it possible to stop an async function abruptly in the middle of execution ?
In my Flutter Web app ,We calling a Future returning function that have some strings processing and also API calls .My need is, I need to stop a async function abruptly in the middle of executionI tried options like CancelableOperation ,CancelableCompleter and Timer...But these classes don't cancel the future itself, rather create wrappers like things where you can use to imitate the cancellation behaviour.That is , The future is still running calling APIs and getting response and processing the response and finally returning resultBut I need to stop the async function without executing even the next line or any inner callbacks, after being cancelled .Is it possible ?

Classic non-configurable CSV parser suitable for most use cases. Pretty fast parsing.
CSV parser (fast_csv) as a result of use of the parser builder.
I don't know why, but the generated parser is about 2.9-3.5 faster than the handwritten csv parser.
Can be used with Flutter.
Allows a bit of configuration - specifying a field separator (when using the extended version of the parser).
But in this case, it will parse the data no faster than a 2.9 times compared to the parser from the csv package.
When parsing large amounts of data, you can speed up parsing by a few seconds. This may be relevant for Desktop Flutter applications.

Does flutter_riverpod support something like this out the box?
Noticed you have to create an army of final variables to reference to the ref.watch method which can grow quickly. So I wrote the following, but i'm wondering if this solution is already supported out the box (and where can I find it) and if not can this be improved any?

class ProviderCollection<T> { final Map<dynamic, dynamic> _items = {}; void add<T>(dynamic name, ProviderListenable<T> provider) { if (name is! String && name is! Enum) { throw Exception("Name must be of type String or Enum"); } _items[name] = provider; } T get<T>(dynamic name) { return _items[name]; } } 

Example:

final providerStack = ProviderStack() ..add<Counter>("counter", ChangeNotifierProvider((_) => Counter(0))) ..add<int>("counter2", StateProvider((ref) => 0)); void main() { runApp( const ProviderScope( child: App(), ), ); } class App extends StatelessWidget { const App({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return const MaterialApp( title: "Example", home: HomeScreen(), ); } } class HomeScreen extends ConsumerWidget { const HomeScreen({Key? key}) : super(key: key); @override Widget build(BuildContext context, WidgetRef ref) { StateController<int> t = ref.watch(providerStack.get("counter2").state); // Counter t = ref.watch(providerStack.get("counter")); return Scaffold( appBar: AppBar( title: const Text("Hello"), ), body: Container( child: Center( child: Text('Counter ${t.state}'), // child: Text('Counter ${t.count}'), ), ), floatingActionButton: FloatingActionButton( onPressed: () { t.state++; // t.updateCount(); }, ), ); } } class Counter extends ChangeNotifier { int count; Counter(this.count); void updateCount() { count++; notifyListeners(); } }

Is there anyway to code with flutter android studio on a figma design, and please don't tell me that i have to use flutter ui because i don't have the time to code the design again.
Actually it's a university project where the groupe was divided into two binomes, one for design and one for coding, the binome design chose to work with figma, and it's the coding turn and it's been a while we since we were trying to code again and we have no time to do the design with flutter ui. Thank you.

Have you ever felt that when you are working on a project you kinda get confused about what to do? Which one should I do first? I always get that so I built a small task manager app that lets you create 5 tasks and set a time for it. The default is (60 mins.). And vola! Work on those tasks.

Firestore filtering and pagination
I have a realtime value list which I am paginating by passing last id of the object,​var eventDoc = _firestore.eventCollection.orderBy(FieldPath.documentId).limit(pageSize);​if (startAfterId.isNotEmpty) {eventDoc = eventDoc.startAfter([startAfterId]);}​In my bloc I have a list of subscriptions for each page,is there any good way to additionally filter this data, for example by name and then return paginated result?

Desktop App Idea - Is Flutter a viable option? [Opinion Based Question]
Hi, I just discovered Flutter and would love to give it a try.I’m planning to build a “secure” app, that will try to ensure credibility.
What I mean by that - I want it to check how many output displays are currently connected, persist fullscreen mode and disable (or catch) any Alt+Tab action (loosing focus from the app). Apart from that one of the main parts would be webcam recording and its processing (probably using some libs). Also I would love it to recognize when it’s running in VM.The catch is, I want it to work on Windows, Mac, Linux. I realize it will require a lot of native code, but also Flutter could save me a lot of work (at least I think), since the app should have several screens with forms, some logic around that, communication with rest api and so on.So the question is. How good is Flutter with such heavy native code requirements?From what I understood from docs, I can use Channels to execute native code, but that seems fishy to me since it’s asynchronous, so I’m worried it won’t be stable and consistent.I’ll appreciate any input to the topic, mainly from more experienced people.Thanks a lot! ^_^
