Some say Dart is bad. I like it for one big reason, language-level meta-programming. Make your own language features!
I feel like I haven't seen this topic discussed before, so I'm discussing it now. I see people who say they dislike Dart due to how verbose or Java-like it is; that it doesn't have the latest features likealgebraic data types / sealed classes / tagged enumsexhaustive pattern matchingnon-nullable types (before Dart added them)higher-kinded typeshooks (like in React)and so on. However, what Dart has that is missing in many languages, even the most popular ones, is reflection, either at compile or run-time. Basically, the language can introspect its source code and can create new classes or functions. What this means practically is that you can create any language-level features that you think are missing from other languages. Sure, it's a little clunky with compiled classes and .g.dart files, and sure it may not be as powerful as Lisp or Haskell, but most people aren't even coding in languages with such features. Javascript has this somewhat with Babel plugins but you won't see most people using them to a large extent.So if you want the features above, some of them have their own packages, like freezed (ADTs, pattern matching), flutter-hooks, dartz (Haskell-like functional programming with higher-kinded types, monads, immutable data structures), and so on. Obviously if these were all language-level features rather than community packages, it would be better, but sometimes the community can do it better. As well, a language can't have every feature under the sun as it would become too bloated, like C++, so at least this is a good alternative.This flexibility, along with the integrated package manager, JIT and AOT compilation to many different platforms like x86, ARM and even Javascript, and the rest of the developer experience is why I personally like Dart.

Function Widgets or Stateless/ful Widgets?
Is there anything wrong with this practice? We all know the boilerplate that comes with extending StatelessWidget.Lately I've been making platonic Widgets with functions using Builder. Is there anything wrong with this practice?

// Outside a StatelessWidget Widget myWidget(BuildContext context, String s) { return Builder(builder: (context) { return Text(s); }); } // ... in some StatelessWidget @override Widget build(BuildContext context) { return myWidget(context, "Hello World"); } 

It seems too good to be true. There has to be some incurred costs to writing Function Widgets. What do you think?

(HELP) How to constantly find a Modal Bottom Sheet's y position?
I have a showModalBottomSheet widget popup and I want to find it's position constantly so I can use this information to animate the border-radius.I don't think this is the best way to do this. It seems I can do this with the animation controller for the bottom sheet if I can get the value for that but I'm not sure how to do that either.I have tried finding the position using a RenderBox but it seems it can only be called once not with every frame.​I'm a beginner with Flutter and Dart so I apologize if this is trivial lol

A Dart/Flutter package for easy validation.
I few days ago I published my first package: https://pub.dev/packages/verifyIt's a pure Dart package to do validations. Validations can be created in many ways and are easy to combine.I also think it's a great fit for validating bloc states for example.The API is very functional and flexible all done with extensions and typedefs. Give me your thoughts about it!
