I did some initial research into how to measure layouts, but that doesn't seem relevant here, as I have the chicken vs. egg problem of needing a Window in order to render layouts that I want to measure... I think?

I saw that Windows allow you to pass in Dp.Unspecified as a way to auto-measure its size, so I was thinking of using that by doing an initial dummy render, but that didn't seem to work. (I used a "firstFrame" boolean, rendering the dummy text area, then set "firstFrame" to false, but it seems that that happened so quickly that the window, when measuring itself, used the composables rendering in a later frame). Anyway, that also seems like a hack...

What I'm looking for I guess is a Composable that I can call within an

application

that can take a font, some text, and give me the size of that text in

sp

or

dp

units.

Nevermind, I think I figured out how to do it with

SubcomposeLayout

based on this answer https://stackoverflow.com/a/70508246/17966710 in combination with Dp.Unspecified.
