Hi everyone, I'm facing this issue, but I've not found a good solution to that:

/Users/ctrltech/StudioProjects/Tmaterials/shared/src/commonMain/kotlin/com/geekpastor/shared/ui/components/singleComponents/AppBar.kt:67:35 Unresolved reference 'painterResource'.

As you can see, it's happening in commonMain module, and I've tried to find a multiplatform library for resources, but it seems to not be stable each time I have tried to install it, it causes other issues. Doo you have ay other solutions that you could suggest me???

Something might be wrong with your setup or configuration? I'm using painterResource with no issues at all at commonMain, this is my import:

import org.jetbrains.compose.resources.painterResource

[Excellence kawej]

What have you installed as a library?

[Pavlos]

compose-multiplatform = "1.8.2"


composeMultiplatform = { id = "org.jetbrains.compose", version.ref = "compose-multiplatform" }

[Excellence kawej]

I've already installed it, so the only thing I've to do is to import it, isn't it???

[Excellence kawej]

Should I install composeMultiplatform as a plugin or a library???

[Pavlos]

Yeah I've also installed that plugin, and created a multiplatform project via Android Studio which also pre-installed a lot of things.

You also need to setup the multiplatform resources if that's not already the case, see https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-multiplatform-resources-setup.html

My plugin, either for IntelliJ or Android Studio, looks like this. Is it the right one???

[Pavlos]

Yes that looks correct I think

[Excellence kawej]

okay...

[Excellence kawej]

thks...

[Excellence kawej]

So now i'm trying to install the composeResources library

[Excellence kawej]

That is the result I get after installing all things

Image(
    modifier = Modifier
        .fillMaxWidth(0.4f)
        .fillMaxHeight(),
    painter = painterResource(id = Res.drawable.ic_launcher_foreground),
    contentDescription = "Logo de l'application",
    contentScale = ContentScale.Crop
)

Unresolved reference 'Res'.

[Adrien de Sentenac]

If you cannot import Res, try adding this in your build.gradle.kts:

compose.resources {
    publicResClass = true
    packageOfResClass = "your.package.name.resources"
    generateResClass = always
}

Then you should be able to import it with:

import your.package.name.resources.Res

See https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-multiplatform-resources-usage.html#customizing-accessor-class-generation for details.

Also, you're using the wrong painterResource, you should import the one from compose multiplatform:

import org.jetbrains.compose.resources.painterResource

which takes a resource as parameter, not an id.
