is this Compose idiomatic? to convert this:

@Composable
fun Example() {
    Row(modifier = Modifier.fillMaxWidth()) {
        Text(
            text = "Left",
            modifier = Modifier.weight(1f),
        )
        Text(
            text = "Right",
            modifier = Modifier.weight(1f),
        )
    }
}

to:

@Composable
fun Example(
    left: @Composable (Modifier) -> Unit,
    right: @Composable (Modifier) -> Unit,
    modifier: Modifier = Modifier,
) {
    Row(modifier = modifier.fillMaxWidth()) {
        left(Modifier.weight(1f))
        right(Modifier.weight(1f))
    }
}

am asking because of passing Modifier to parameter `@Composable`s.
I want to hide Modifier.weight(1f) and I want everything using Example to have exactly 2 elements that occupy 50%/50% of space, without wrapping left and right into Box, for example, and applying Modifier.weight(1f) to Box container

TLDR: Consider creating custom layout

[Marko Novakovic]

I did but I want to avoid that too 😄, there is more to it than what I posted. what I posted is just a gist of it and it’s actually more complex which why I want to avoid writing custom layout

[Filip Wiesner]

This is my subjective opinion but this feels wrong and because you are asking this question, it probably feels wrong to you too.
You have no guarantees that your child will use the passed modifier so the other logical argument "_I want everything using Example to have exactly 2 elements"_ does not feel like good enough reason and it basically becomes just a Row wrapper

I would be interested in more information about why you want to avoid a custom layout?

[Filip Wiesner]

In your example the composable just divides two content lambdas into equal space but that does not seem like is worth the effort of having function for that. (subjectively)
Maybe describe your usecase more so someone can give you better answer than mine

(sorry for editing my messages constantly. I am still thinking about it 😄 )

without wrapping left and right into Box

Also curious for the reason for wanting to avoid that as well?

[Marko Novakovic]

@Filip Wiesner yes it feels wrong 😕. left and right should support layouts like Column, for example, and than (depending on what left and right are) alignment changes. it should support top and center vertical alignment etc. maybe it’s just too late and am overly complicating this in my head 😄

[Marko Novakovic]

@Alex Vanyo I was worried about performance and I was lazy to go through docs and remind myself how Compose handles it 🙂. and it felt wrong, not as wrong as passing Modifier back to parameter `@Composable`s but still wrong

now that I typed it out I see how stupid it is, I won’t delete it for context sake

[Filip Wiesner]

Rubber-ducking is the best way to prototype. You are welcome 😁

[Marko Novakovic]

yeah 😄 thank you 😁
