Is it possible that 
imageFromResource
does not work in 
repo
?
I added a drawable but that always return 
null

is it a bitmap or a vector? at the moment it only does bitmaps

the old fashioned 5 .png files 😄
Oh, actually, it also has a 
xml
for 
anyDp
Can this be the problem?

I'm agitating for something 
Drawable
-like in compose but without `Drawable`'s regrets
not there yet though 🙂

Removing the 
xml
files now won’t crash the app 😄

the current situation with vectors being handled at composition time makes things awkward

@Adam Powell Drawables without all the things that make them more like widgets would be fine

Yeah exactly
Model observation should give us nearly everything we need in terms of smarts where it's needed

Invalidation for changes stays implicit, if something in a drawable is backed by 
@Model
then that value changing will trigger redraw

how is this related to getting a 
null
value when there’s also a 
xml
for 
anyDp
?

Same with any kind of preferred size being read by the composable that lays out and draws it
Just that we can unify vectors and bitmaps so you don't have to see this distinction
One resource load that just works

Oh, I see, it was an internal discussion 😄

imageResource
blindly tries to decode a bitmap which is why you get null
An XML is not a bitmap

Luca Nicoletti

11/19/2019, 4:21 PM
Yeah I know that
My question was more: why is it retrieving the 
xml
file alongside all the ones available

It was the variant of that drawable selected for your current configuration
Android resources treat the two as equivalent in terms of identity
And compose isn't currently set up to play as nicely with that as it needs to be
