Flutter web performance with getx

Question

I'm using getx state management for flutter. I read a few articles (blog.codemagic.io, itnext.io) that explain that we shouldn't use methods for widgets because you can save CPU cycles and use them with a const constructor to make rebuild when only needed and much more benefits.

My question is, Is it necessary to use classes instead of methods when I use getx?

Answer 1

The best way to figure this out is to actually dive into the code of GetX itself.

If you look at the Obx source code, you will see that Obx itself is actually a widget (with a const constructor, to boot). So, when you're typing Obx(...), you are not calling a helper method, but actually instantiating a widget class.

So, to answer your last question: no, to use GetX you don't need to do any extra class wrapping. Obx itself is already a Widget class with a const constructor.
