Is there a way to provide some `@Preview` placeholder feature? For instance if I'm creating a custom `Painter` and I want to provide a preview for that?

Example: I've a QRCode to be generated and I want to provide a preview that look like a QRCode without actually running the code to generate it

There’s no way to magically replace the content of an arbitrary composable. I think you’d have to write a separate fake QR code composable and use that in your preview.

I suppose Coil and any other libraries for image loading have the same problem with previews

It is actually possible:
```if (LocalInspectionMode.current) {
  // inspection mode (preview)
}```
