Flutter Stateful or Stateless?
I tried to create a simple form to validate user input data.

class UserForm extends StatelessWidget { final _formKey = GlobalKey<FormState>(); final TextEditingController usernameController = TextEditingController(); UserForm({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return Form( key: _formKey, child: Column( TextFormField( controller: usernameController, validator: (value) { if (value == null || value.isEmpty) { return 'Please enter something'; } return null; }, autovalidateMode: AutovalidateMode.onUserInteraction, ), ElevatedButton( onPressed: () { print(usernameController.text); }, child: const Text('Check'), ), ), ); } } 

When I type something and delete it after, I get the error message Please enter something under the textfield.​I saw an official demo example with a form validation here: Build a form with validation | Flutter .Now, my question is: why do we need a StatefulWidget for a form, if the error message gets displayed in a StatelessWidget. The value of TextFormField is changing, not the custom form widget I created.​Can somebody explain me when to use stateless and when stateful?

Your app Terms of Service
Hey guys,I'm trying to integrate Twitter auth/share into my app, but it appears to require a link to my apps TOS, which I currently don't have. Is there a small amount of TOS that is acceptable (ie. I store your email address because we need it for the user, but if you delete your account everything is removed), or what?TOS generators seem to want $50 or more, which is great except for my app is meant to be free, and I'm already trying to figure out how to pay for the Apple store.Any suggestions?

App Logic in repository or Bloc?
So this is something I have been struggling with. In my app I am using a UI -> Bloc -> Repository -> Provider -> Data pattern. Currently my provider just handles fetching the data and my repository class is doing some additional logic. My question is, should that additional logic really be moved into Bloc vs the repository? All my Bloc does is react to status changes from my Repo and wait for the UI to send a login/logout event which it then calls on the repository.​Example: LoginProvider: Pass the data to our backend.Repository: Call provider to actually trigger login and also store the received token to a secure Hive storage and add the authenticated value to a stream.Bloc: Read the stream from the repository and react to changes in that stream.UI: Listens to the Bloc for changes in the State (status from repo and user) and also add the Login event on button press.

My First Full Flutter App
This is the first time I make a ffull flutter app. although it does not use the internet but it still has a large code base and I refactored many parts of it from scratch until I reached a somehow state of satisfaction with it (I still have alot of optimal patterns to learn like coding without side effects...).​Anyway the app records, plays, and edits sound (using FFMPEG package for editing the sound).I will link the code on github here and you can fork/clone the repo and run the app. I havn't test it on ios, only android. Feel free to give me feedback about the organization of the code it will be much appreciated. The UI is not my concern now as the code cleanness is the greatest deal ever and once that is done everytthing else follows.
