In Text, is there a way to specify the minimum text width in terms of em?
I have a composable that displays a number and an icon. I want the icon to not move when the amount of digits in the number changes. The maximum amount of digits is 3, so I would like to somehow specify the width of Text to be 3 em.

Sorry i do not know if this is possible but you could use a Row and than add a Modifier.weight(1f) to the Text. The row should have a Modifier.preferredWidth(10.dp) or something like that (dependent on your font).

[Julius Marozas]

Yeah, I got it working through trial-and-error. But it would be more convenient and font-agnostic if I could specify something like Modifier.preferredWidth(3.em.toDp()) (similarly to 10.dp.toPx()).

Turned out that is possible:
with(DensityAmbient.current) { 3.em.toDp() }

I’m sorry, I tried it out and it results in java.lang.IllegalStateException: Only Sp can convert to Px 😕

@Denis Ismailaj, check this message https://kotlinlang.slack.com/archives/CJLTWPH7S/p1612638156434300?thread_ts=1612009094.039300&cid=CJLTWPH7S. It uses TextDelegate (that's an internal API, afaik). You need to set Constraints you need. It's another question how to convert ems to px
