since painterResource throws exception for some drawables and we can't write try/catch in @Composable functions, how can I work around not crashing my app?
painterResource calls loadVectorResource who calls loadVectorResource

private fun loadVectorResource(theme: Resources.Theme, res: Resources, id: Int): ImageVector {
    @Suppress("ResourceType") val parser = res.getXml(id)
    if (parser.seekToStartTag().name != "vector") {
        throw IllegalArgumentException(errorMessage)
    }
    return loadVectorResourceInner(theme, res, parser)
}

It crashes for an image such as this

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="<http://schemas.android.com/apk/res/android>">


    <item>
        <shape android:shape="oval">
            <solid android:color="@color/colorBardeenBrand" />
        </shape>
    </item>

</layer-list>

We'll, that isn't a <vector> resource, so the crash makes sense

[Fabio]

not to me
painterResource also loads things that are not vector

[Fabio]

so what's the alternative? I could copy/paste the code for the private/internal functions and modify it to inflate shapes into bitmap and pass it to Image but wondering if there's an alternative

[Fabio]

btw in other situations I could at least catch the exception, but is there something equivalent for @Composable ?
as a side note, if there's any docs/blogs/vlogs about the try/catch decision I'd be interested in reading it

You can use DrawablePainter from Accompanist https://google.github.io/accompanist/api/imageloading-core/imageloading-core/com.google.accompanist.imageloading/remember-drawable-painter.html

I'm away from computer now Australia timezone) but will def stop there.
Btw I've been using accompanist coil, curious to know why there's no network error placeholders? This is the exact use case I'm working here.
I'll dive in accompanist GitHub issues by Monday btw

There is, you just need to use Coil’s API to do so. https://github.com/google/accompanist/blob/main/sample/src/main/java/com/google/accompanist/sample/coil/CoilBasicSample.kt#L90

works like a charm! thx @cb
It was a bit confusing because I can't remember seeing that in the docs, but the lib is super awesome. Btw we're going live with it on our app with -coil and -pager this week 🙂 , image placeholders are just the cherry on top

Awesome! 🦜
