How can I set a preview placeholder for a Coil image? It lacks an alternative to
tools:src
. The Accompanist version had a
previewPlaceholder
. But after Compose support moved to the Coil library proper, it was removed. Are there any solutions?

According to the Coil documentation you need to set
placeholder
within request builder scope.

That's something different,
placeholder
sets the image visible in the app during loading, not a @Preview replacement image.
s
No, it is also working for Preview. Please, read the doc first https://coil-kt.github.io/coil/compose/#migrating-from-accompanist
previewPlaceholder is removed. ImageRequest.placeholder is now automatically used if inspection mode is enabled.

I know the placeholder image is visible in Preview. But I don't see how that solves my problem. Like I said, I am looking for something like
tools:src
in ImageView or
previewPlaceholder
in the previous version of Coil. They don't affect the app, unlike what you are suggesting. I don't want my placeholder to be visible at runtime.
s
Oh, I see. AFAIK, it doesn't exist for Coil.
You can workaround it with if (LocalInspectionMode.current) { // set your placeholder image }

That could work, thanks.
