Has anyone had problems with ImageVector being remembered incorrectly? I’d like to know if this is a bug in rememberVectorPainter() or if I’m just doing something silly. See thread for details 🧵 ➡️

Consider the following code:

val icon = if (selected) MyIcon.Selected else MyIcon.Normal
val color = if (selected) Color.Green else Color.Black
Icon(
    modifier = Modifier.size(48.dp),
    imageVector = icon,
    tint = color,
    contentDescription = null,
)

MyIcon.Normal and MyIcon.Selected are both `ImageVector`s with identical `Path`s but different line stroke widths, and the name argument provided to the builder is different for each of them too.

The problem I’m having is that code doesn’t update the icon when the selected variable changes. The colour updates as expected but the image itself doesn’t, it continues to remember the Normal version 🤔

I’ve tested it in reverse too — if I start with the Selected version for initial composition and then switch to Normal, it doesn’t change

Maybe the problem is related to the selected boolean. Print it to check if it actually changes or paste the full code

That was the first thing I checked 😅 I’ve verified the boolean is all good, in fact I debugged and set a point to print the name field of the ImageVector and I see the change occur there
