I'm using ConstraintLayout. Can anyone tell me if I need to specifically set the width of BottomNavigation or is there a way to make it fill the parent (Modifier.fillMaxWidth() does nothing)?

Edit:
performMeasure in ConstraintLayout.Measurer does this

state.width(if (constraints.hasBoundedWidth) {
    Dimension.Fixed(constraints.maxWidth.value)
} else {
    Dimension.Wrap()
})

I'm guessing it would have to call Dimension.spread() in order for it to work in my case or am I wrong?

I haven’t played with ConstraintLayout yet, but it looks like you need to set something like bottomNavigation constrainHorizontallyTo parent inside a ConstraintSet

@maciejciemiega My constraints are all set

val constraintSet = ConstraintSet {
            val bottomNavTag = tag(bottomNav)
            val viewsContainerTag = tag(viewsContainer)

            <http://viewsContainerTag.top|viewsContainerTag.top> constrainTo <http://parent.top|parent.top>
            viewsContainerTag.bottom constrainTo <http://bottomNavTag.top|bottomNavTag.top>
            viewsContainerTag constrainHorizontallyTo parent

            bottomNavTag.bottom constrainTo parent.bottom
            bottomNavTag constrainHorizontallyTo parent

        }

then 🤷‍♂️ 😞

Maybe it’s not working until https://android-review.googlesource.com/c/platform/frameworks/support/+/1169988 is released?

Oh yeah, that would make sense, I guess I have to wait for dev09 😅 Thanks for finding it!

Yep, setting dimensions is not possible in dev08, but should come in the next release 🙂
