I have

Box(modifier = Modifier.heightIn(min = 40.dp)) {
  Canvas(modifier = Modifier.fillMaxHeight()) { ... }
  OtherContent()
}

and Canvas composable doesn't fill 40.dp, and is 0.dp in height actually. If I swap heightIn with height(40.dp), then it works.
How do I make it so that child either fills 40.dp or more if total Box height ends up to be larger (due to OtherContent)?

[Lucien Guimaraes]

have you tried requiredHeight(40.dp) instead of height() or heightIn() ?

[dimsuz]

hmm. it would still not permit content to be larger than 40.dp. But you gave me an idea to try requiredHeightIn 🙂

[dimsuz]

...and it didn't work! (at first I thought it did, but forgot to delete height modifier)

[Lucien Guimaraes]

Sorry I wanted to say heightIn() but you already tried it without success 🤔

[Lucien Guimaraes]

did you set .heightIn(min = 40.dp) or just .heightIn(40.dp) ?

[dimsuz]

first, but they're equivalent in case of min 🙂

[Lucien Guimaraes]

you sure it's the same ? In the doc it's set as Unspecified by default

[Lucien Guimaraes]

@Stable
fun Modifier.heightIn(
    min: Dp = Dp.Unspecified,
    max: Dp = Dp.Unspecified
) = ...

[dimsuz]

I mean specifying name of the first argument doesn't change semantics of the call, min will be set to 40.dp

[Lucien Guimaraes]

ah my bad, I misunderstood

[Lucien Guimaraes]

the issue must be related to fillMaxHeight() in your Canvas then, if you replace it with heigh(40.dp) is it working ?

[dimsuz]

yes, but that's not my intention. I want the canvas to fill the whole box height, see my original question. Box might be bigger than 40.dp

[Lucien Guimaraes]

I just wanted to know if it was working with height(), so here the issue must be related to Canvas being unable to know the height of your Box. So you might need to go through intrinsic measurements

[dimsuz]

Heh, but I mentioned that it works with height in my initial message.
I'll try to check if intrinsics will help me.

[dimsuz]

Nope, If I put height(IntrinsicSize.Max) on a Canvas, this doesn't help either...

[Lucien Guimaraes]

Heh, but I mentioned that it works with height in my initial message.

I though it was for the box modifier, not the Canvas

Nope, If I put height(IntrinsicSize.Max) on a Canvas, this doesn't help either...

If I'm not mistaken the IntrinsicSize should be used in your parent Composable, not your children Composables

[dimsuz]

But I want my Box to be 40.dp or larger if content is larger. I can't put intrinsic modifier on it.
