Hi Guys, I got an interesting question about jetpack compose margin. As we can implement margin using padding or Spacer; Is it better to use padding instead? I said that because I now each composable is passed through compose, layout, drawing steps and I thought setting padding is just done on layout phase of that composable but Spacer will be passed in 3 phases separately. And Spacer creates extra Layout. Am I right?!

It's very unlikely that there is a significant performance penalty for using Spacer. It's not an Android View, and is very lightweight

Spacer does typically make for better reusability in components. There were some good convos about this a while back (like a year ago+) if you search this url in the chat history you'll get some details, but then again this blog post pretty much nails it. https://mxstbr.com/thoughts/margin/

Spacer

is very deliberate; if you want to add space between something, then do it explicitly with a component that's made for it, rather than exploiting the padding/margin of something else.
