Aside from setting IntrinsicSize.Max on the Row height and using fillMaxHeight on the Divider within it, is there another way to make the Divider fill the maximum height of a Row that contains other Composable elements with dynamic heights such as Text? I can’t use IntrinsicSize.Max since I’m using BoxWithConstraints within the Row, which is not allowed in Compose(will get a RuntimeException).

That is one of the primary uses for intrinsics.

And this restriction is one of the reasons to avoid BoxWithConstraints as much as possible.

In my case, it’s a little bit complicated. But I do need to use BoxWithConstraints to get the max width then do some calculations… So I thought getting rid of IntrinsicSize.Max and to achieve same effect using another way.

[Zach Klippenstein (he/him) [MOD]]

Are you composing different things based on those calculations?

[lesincs]

So I give this maxWidth manually to Coil ImageRequest, so it can load network images with proper dimensions. And why Coil could not figure out the size constraint itself is because I put the Coil Image as an InlineContent of a Text, so the constraints is fixed from the PlaceHolder not parent Composable. I am basically implementing a markdown display feature that an image might be inserted inside a text. The idea is once the image is loaded successfully, I can reset size of the PlaceHolder so it can display the image properly. 😅

[Zach Klippenstein (he/him) [MOD]]

Yea, I don't think you need BoxWithConstraints for that

[lesincs]

Any other way I could get the maxWidth right away without using BoxWithConstraints? I actually thought of other solutions such as getting the width from the Modifier.onSizeChange{} callback. But I am afraid this would be after some frames and it might too late as I basically need to pass that maxWidth limitation immediately to the ImageRequest .

[lesincs]

My current solution for getting rid of IntrinsicSize.Max is I am using Modifier.onSizeChange{} to get the maxHeight of `Divider`'s sibling Composables and then set the maxHeight to the Divider itself. It works 😅

Why do you need to pass those constraints in manually? Coil's docs say AsyncImage already does this itself, and there seem to be ways to get even more involved if you need (ConstraintsSizeResolver)

[Son Phan]

Could you try replacing Row with ConstraintLayout instead?
Link the `Divider`'s top and bottom to the parent's top and bottom, then add height = Dimension.fillToConstraints should work.

[lesincs]

@Son Phan wow, I just tried and it does work. Nice! And I just realised I have not used ConstraintLayout for ages!🤣

[lesincs]

Why do you need to pass those constraints in manually?

In a normal layout I don't need to and Coil can figure it out by the constraint from parent. But in my case the image is wrapped in an InlineContent and then passed to the Text - so now the constraint becomes the PlaceHolder size of the InlineContent which is not ideal because the size of PlaceHolder is hardcoded initially and usually pretty small.

Couldn't you just pass a custom SizeResolver then?

That's exact what I am doing now. My code to build the ImageRequest is like:

val request = ImageRequest.Builder(context)
                    .data(inlineImage.url)
                    .size(Dimension(maxWidthInPx), Dimension.Undefined)
                    .build()

The size(...) in the chain creates a custom SizeResolver under the hood. But here I need the maxWidthInPx is which coming from BoxWithConstraintsScope.constraints.maxWidth ...
