Creating Widget as a local variable?
I myself prefer to separate everything into its own StatelessWidget. However, I came across some code that initialize the widget as local variables and then use it. While I do not like it, but I am struggling to find a reason of why we shouldn't do it.``` class MainWidget extends StatelessWidget { final _firstText = const Text('first text'); final _secondText = const Text('second text');@override Widget build(BuildContext context) { return Column( children: <Widget>[ _firstText, _secondText, ], ); } }

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.

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.March 28, 2020 at 12:39AM by satvikpendem

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
