Is there an equivalent to 
View.setVisibility
on Composables? I’d like to hide a Composable when needed but not just change its opacity because this means it still catches onClicks!
I found some kind of solution, not one that I really like I must say:
Copy code
var modifier = Modifier.fillMaxSize()

        modifier = if (showProgress) modifier + Modifier.noTap().drawOpacity(1f)
        else modifier + Modifier.drawOpacity(0f)

Don't add it to the tree then? You can do that with a simple if. Unless I'm not understanding what you want to achieve.

I thought the idea of visibility in compose is not rendering it in code
Copy code
if (showProgress){
  ProgressDialog(...)
}

That's the cool part of being declarative :D

Yes, it seems that 10 years of non-declarative UI molded my brain to think in a certain way 😂

So far I was doing it exactly as stated above, not adding it in the tree. That's the equivalent of 
gone
, out of curiosity what about 
invisible
?

I still don't get it. Would someone help clarify for me please? It's already in tree. How to remove it then?

simply use the snippet I put above, @composable functions define the components on every recompose

Composable's have the ability to recompose by design. If you don't need the view to be present simply don't add it to the tree like others have stated :)
