I made an early draft of a form library called Former that is inspired by Formik.
One of my favorite react libraries is formik. It is an elegant form building library that drastically reduces boilerplate for keeping track of values, form validation, and form submitting. As far as I know there isn't anything similar in the Flutter world, so I tasked myself to make one. I would really appreciate feedback from the community!Featuresdisable entire formdeclarative form validationno more controllers/manual tracking of valueseasy error handlingExampleFirst off, some simple example code.The form:``` part 'my_form.g.dart';class MyForm = _MyForm with _$MyFormIndexable;@Formable() abstract class _MyForm implements FormerForm { String username = ''; String email = '';@FormableIgnore() String ignored = '';@override Future<void> submit() { // TODO: implement submit return Future.value(); } } ```Consuming the form,MaterialApp( title: 'Former example', home: Scaffold( body: SafeArea( child: Former( form: () => MyForm(), schema: () => MyFormSchema( username: StringValidator() ..min(10) ..max(50), email: StringValidator()..email(), ), child: _Form(), ), ), ), );...and the _Form widget:Column( children: [ FormerTextField(field: MyFormField.username), FormerError(ofField: MyFormField.username), FormerTextField(field: MyFormField.email), FormerError(ofField: MyFormField.email), ElevatedButton( onPressed: () { Former.of(context, listen: false).submit(); }, child: Text('submit'), ), ], );Behind-the-sceneAs you may already have noticed, this library relies on code generation to provide the flexibility of formik. The library will generate three things:A class that makes the form "indexable" via the bracket operator.An enum class that contains all the fields of the form to avoid magic strings.A schema class that lets you specify the schema of the form.Behind the scene, everything is being keep tracked of with a ChangeNotifier which is provided by a ChangeNotifierProvider. Every widget under the provider can access the form via Former.of(context). That means, apart from the built-in widgets that are provided by Former, you can make your own form widget that consumes the form.Githubformer_genformerIt is still very early in the development stage, so features are not at all complete.Again, I would really appreciate feedback from the community, so no matter how critical, just bring it on!

Looking for flutter mentor!
Hello everyone, I am new to flutter and looking for a mentor to guide me in my learning journey. I have good experience with Python and got amazed by cross platform application development capabilities of flutter and started learning it.I would like someone to talk to, ask basic-dumb flutter questions, discuss projects- implementation approaches, share/exchange code knowledge, review my code.I am open to connecting with other flutter learners for collaboration. Please feel free to comment or send a DM if interested.

Flutter Dev on M1 MacBook or Mac Mini
Hi everyone. I'm about to purchase a Mac of some sort for the sole purpose of building, testing and deploying an app for IOS. The bulk of the development will be done on other systems while testing for Android & Web, so day-to-day use is not something I care much about.The current plan is to pick up a Mac mini (M1) with 8Gb of memory (cheapest option). Just wanted to see what the community thinks before moving in on with the purchase. Here are a few things I'm wondering.Do you have issues running Android Studio / building flutter apps on M1 Macs?Should I go for 16 Gb of memory? Is the performance on an 8 Gb M1 horribly slow or unable to complete builds?Any other thoughts?

I recently updated my project from v1.22.6 of Flutter SDK to v2.0.6. But I am not able to build the iOS build.
Recently, I have migrated my project from v1 embedding to v2 embedding in flutter and since migration, I am facing an issue of build creation for ios. Whenever I start project building on pod install command it give me an error.​[!] Invalid `Podfile` file: no implicit conversion of nil into String.# from /Users/cbindia/Documents/mpa_app_test/ios/Podfile:57# -------------------------------------------# unless File.exist?(copied_framework_path)> FileUtils.cp_r(File.join(cached_framework_dir, 'Flutter.framework'), copied_flutter_dir)# end# -------------------------------------------​I tried all the different ways mention in GitHub like removing Podfile and Podfile. lock. Updating version, just one thing is not checked like deletion of ios folder and use flutter create which I can't do in the project because it may give conflict for the app on bitrise.Any help appreciate it. If Flutter team can point what step need to done

AR Core on Flutter vs on native Kotlin
I will be working on a open source project with a Museum over at a my country and we are looking into creating an AR or VR experience to view artifacts and sceneries in a virtual enviroment. I am a React/React Native developer and support for AR and VR is not good imo or atleast I have not found a library yet. I've been thinking on going native with kotlin and AR Core and further down the line learn Swift, but I just found out flutter has a plugin for AR Core, so I was wondering what are your opinions or how has your experience been when working on AR or VR apps using Flutter?

Is there any way of getting 4 space indent in Android Studio ?
2 spaces indent is just too small for me, I can't follow the code.From version 4 they removed the custom formatter, and now even the workaround that I found here: https://youtrack.jetbrains.com/issue/WEB-41628 isn't working anymore.Whomever came up with the idea of forcing everybody in the world to use their preferred formatting style can go sit on a cactus, because they are a pretentious asshole.I read the "reasoning" behind it, and it's BS. If you want all public code to be the same, enforce the formatting on packages submitted to pub.dev.But for my own private code that will never be made public, I should be able to use whatever the hell formatting style I want.This makes me so angry and frustrated I might drop Flutter/Dart altogether like a bad habit despite having spent about 2 years on it, and having developed a mobile app and a desktop app so far.And the answers from the guy from JetBrains don't help, either, acting like yet another pompous asshole.All this could have been avoided by enforcing the usage of TABs and letting each dev decide the size of the TAB. That way repository code can be the same but it can look different in each IDE.It blows my mind that so many devs are for spaces instead of TABs, when TAB is the interface, and the spaces are the implementation. Use the interface, then define your own implementation.

Spotify SDK or MusicKit on Flutter
Warning - non programmer probably asking basic questions 🙈Hi guys,I am the owner of a native iOS app, MusicHub. MusicHub currently uses the Spotify API to pull information, in future I will want to implement its full SDK so the users can play music through the MusicHub.I also want to create MusicHub on android and I have just discovered Flutter. It seems awesome!I’m just wondering if anyone has had any experience with either the Spotify SDK or Apples MusicKit to pull song information and play music on both iPhones and Androids? Does it work?Any thoughts or advice before I hire a dev would be greatly appreciated. Thanks
