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), ], ), ); } }

Is it necessary to know how to know native development (swift, kotlin, etc) to be a competitive candidate for a team?
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.

On-device object recognition and image analysis/processing
Hi guys, I want to ask what are the possible ways to implement this?Basically I want to use the phone's camera to capture two images and recognize from those images if they contain a specific object. The images will be captured in a controlled environment (i.e. specific distance, lighting, etc.) There is also a comparison between the images, and identify if the captured objects are the same or not.What I have in mind is to use TensorFlow Lite and train a model for object detection, and then use this package tflite. And use OpenCV for the comparison, but I don't think there is a complete implementation of this in Flutter.
