Is there some helper function for when you want to display a drawable resource (ID) but don’t know whether it is a vector drawable or a bitmap?

In my use case, I have a drawable resId which is sometimes overridden by a vector resource, and sometimes by a bitmap.

sounds #compose-android specific

painterResource() should work with vectors and bitmaps, just not other types of drawables

[ephemient]

if you need support for all types of drawables, there is accompanist-drawablepainter

Thanks @ephemient So, I’ve just converted my icon: ImageVector args to icon: Painter and that seems to work well. It seems easy to convert from various image types to Painter. e.g. Icons.Outlined.MailOutline to rememberVectorPainter(image = Icons.Outlined.MailOutline) and resource id painterResource(id = iconResId) so when declaring composables, seems better to accept Painter than ImageVector or resource ids, right?

[ephemient]

painter is more general, it can be a gradient or a wrapper like https://kotlinlang.slack.com/archives/CJLTWPH7S/p1678201069992749?thread_ts=1678194581.293459&cid=CJLTWPH7S

Right, yes. When we look at the Icon composables they all call through to the one that takes a Painter, so yes that seems like a good general option,

Fun fact: painterResource detects whether the resource ID is a vector vs bitmap simply by checking whether the path ends in .xml!
