How to Make your own widgets????
So now I am an Intermediate flutter developer. I have used Material Design and Cupertino Design so far. I tried to use the new Fluent App design but it was a bad experience(this package has poor documentation). So what if, I need to design my own Style of Ui, how can I design my own designed widgets ??? I use illustrator/figma/xd to design. How to make the graphics work for flutter? How does this custom design thing work?

During the pandemic we all got used to online events (thank you WiFi!). The main advantage of online events is being able to participate from your home, office or deckchair. BUT in person events have the major advantage of face-to-face interaction and sandwiches made by someone else.
Flutter Heroes, happening on 11 March, will be both an online and in person event.

Flutter Google Group should be fixed or retired
I belong to the Flutter Google Group flutter-dev.It is essentially a ghost town. Very few postings, a few a day.There is even a recurrent (several times in one day) spammer who has never been blocked.I guess I'll just leave, but it should be either at least rid of spammers or closed down or at least not recommended on the Flutter site.

I have seen $ before class names in dart/flutter. What purpose this "$" symbol serve in these below packages.There is a code in this package rx_bloc. How is a class extending itself with a $ sign?
class CounterBloc extends $CounterBloc{}And why is this auto_route package using a $ to extend another class
class AppRouter extends _$AppRouter{}Please someone explain it ?

Why are InternetAddress.lookup('') requests not shown in the Dart Devtools Network Profiler?
I was looking to a package that checks if the device is really connected to internet. I found this one: flutter_network_connectivity and it works fine.Looking into the code I saw that this package uses InternetAddress.lookup('<custom website>') to check the connectivity.So I expected it to make http requests visible to the network profiler, but this actually doesn't happen.Anybody knows the difference between InternetAddress.lookup('') and a normal GET request?

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.
