Which design pattern to use in app ?
I was actually trying to make a complex app, in which one state depends on another and so I used bloc pattern for that, now I facing very difficulties in implementing some of its features, So can someone suggest which design pattern is best for making a complex app somewhat like Flipkart.

Apps that convert designs to code.. Has anyone tried supernova studio?
Came across a macOS app called Supernova that allows users to "Convert designs into native mobile apps". What's the catch with apps like this? Is that saying that you can design an app and turn it into a fully functional iOS app without knowing a substantial amount of Swift? I think code gen would be helpful for a lot of the UI.​Has anyone tried supernova studio? (supernova.io)

Any IOS Developers Convert to Flutter?
I know iOS developers are passionate about their ecosystem and all things Apple and was wondering if any have made the leap to Flutter. With SwiftUI coming out I figured it might not be that many that use Flutter, but it will be interesting to know.

Why is TextEditingController always used in Stateful widgets?
While reading the flutter documentation, I came across this article that shows how to handle changes to a text field. What I found interesting is that in this and all other articles regarding TextEditingController, the TextEditingController is always used in a Stateful widget regardless of whether that widget needs to be stateful or not.What is the reason that TextEditingController is always used with Stateful widgets?

Toggled button with neomorphic design
Hi all,​Just discovered this new design and decided to give it a shot,​I managed to create a round widget as a button, on press it goes down,https://imgur.com/gallery/3xt7WY9​I used a linear gradient to create the effect while down and boxShadows while up. However the LinearGradient doesn't create the exact same effect as the shadows.https://github.com/Germain-L/flutter_neumorphism/blob/master/lib/widgets/round_button.dartHere's the code for it.​The issue with this implementation is that the linear gradient creates a curved effect when the button should be flat. What are your thoughts on this design?

Struggling with animation in Flutter. Help!
Hey all!My team recently contracted a team to build us an app and the developers have built it in Flutter. We'd like polish the app by animating a few elements but this seems to be a sticking point. Our friend is a brilliant animator/illustrator but primarily only works in After Effects and since he's doing this for us as a favour its a bit of a tall order to ask him to learn a whole new software package, Flare, to do the animations.So my next port of call has been Upwork and Fiverr but there doesn't seem to be a whole lot of designers on there who are familiar with Flare. It's also a bit difficult to sift through search results for 'flare' on Dribbble and Behance since its such a common word.Can anyone eitherPoint me in the right direction of where the flare animators are hiding (website, subreddit, etc) orTell me how we can best reliably our After Effects animator? We've looked at using Lottie + Body Movin but unsure how reliable this is.Super grateful for any help!

Is anyone using Ryzen here?
I'll be upgrading my PC soon. Thinking of going for Ryzen 7 2700x, now wondering if it would play nice with the Android emulator. My worry is that because the emulator depends on Intel HAXM, so if I go for Ryzen, the emulator would be too slow to use.Is anyone using Ryzen + Windows, how is the emulator's performance?Just for the record, I'm not gonna change to Linux. My work requires .NET's WCF, so I'm stuck with Windows.

Function returning Widget vs instantiating custom Widget
Say I'm refactoring the boilerplate "counter" app. And I extract the following body attribute into a function:

class _MyHomePageState extends State<MyHomePage> { int _counter = 0; void _incrementCounter() { setState(() { _counter++; }); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar(title: Text(widget.title)), body: _bodyContent(context), floatingActionButton: _mainButton() ); } Center _bodyContent(BuildContext context) { return Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ Text('You have pushed the button this many times:'), Text('$_counter', style: Theme.of(context).textTheme.display1), ], ), ); } 

Why / when would I do that, rather than, say, create my own stateless Widget, a la:

// ... body: BodyWidget(_counter), // ... class BodyWidget extends StatelessWidget { final int counterValue; BodyWidget({this.counterValue}); @override Widget build(BuildContext context) { return Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ Text('You have pushed the button this many times:'), Text('$counterValue', style: Theme.of(context).textTheme.display1), ], ), ); } }

I recently spoke with someone who’s been working in the industry for a while and he said it was important for me to learn native development even though I already have a good handle on Flutter.What do you guys think?

Need help in adding PayPal plugin in flutter
Hi everyone,I am a beginner in flutter app development.Knows just very basic of it, learning reading other's code over GitHub and stack overflow.I am currently working on an app with requirement of PayPal integration, currently using https://github.com/DeligenceTechnologies/Braintree-Payment-Gateway-for-Flutter plugin for that. Up until this is working fine, the only issue i am facing is when the webview opens and the PayPal page loads with a button showing "Proceed with sandbox purchase". When i click that link instead of redirecting back to the app screen the app crashes and the device connection is lost.One more thing i have noticed is that the log shows that the "payment is successful".You can check my flutter doctor vI have been debugging this from the past week but having no progress, any input will be appreciable.Thanks and Regards.
