Is there a way to ensure that a composable would always be square? So that regardless what the size of its content, the Width or Height would always be equal?

I tried:

modifier.layout { measurable, constraints ->
    val placeable = measurable.measure(constraints)

    val wrapperWidth = placeable.width.coerceIn(constraints.minWidth, constraints.maxWidth)
    val wrapperHeight = placeable.height.coerceIn(constraints.minHeight, constraints.maxHeight)
    val size = wrapperWidth.coerceAtLeast(wrapperHeight)
    layout(size, size) {
        placeable.placeRelative(0, 0)
    }
}

But I am only altering the position here since I already measured the placeable. Any hints?

Modifier.aspectRatio(1f)

Aspect ratio seems to completely consume all the space though...

[allan.conda]

Not really, we use it for thumbnails

[allan.conda]

One of the dimensions should be defined I think

[allan.conda]

it has to relate to something

[allan.conda]

wrapContent() works too if I remember correctly

[allan.conda]

I think it takes the bigger side and matches the other

[allan.conda]

We use it in combo with `fillMaxWidth`or weight, wrapContentSize. It really depends on your use-case

[Archie]

doesn't work unless you define the width or height or else it fills the whole space... your thumbnail probably have defined width or height thats why

[Archie]

the problem is that I can't define the width or height as it needs to adjust to its content...

cc @Adam Powell I think maybe this would require multi-pass layout, which is prohibited?

[allan.conda]

@Archie I see, I got the difference from your use case

[Archie]

@jim I'm also thinking if SubcomposeLayout would be the best fit for this usecase? I haven't really tried not really sure.

Did you tried this? :

Modifier.preferredHeight(IntrinsicSize.Min).aspectRatio(1f)

[Archie]

@Timo Drick, it would work. That assumes that the largest dimension is Height... If the bigger dimension is Width, then it will fail.
