Is there a way to detect if your composable is being rendered as a Preview? Akin to `isInEditMode()` from standard Android.

Not sure if it works on Desktop but for Jetpack Compose you can use <https://developer.android.com/reference/kotlin/androidx/compose/ui/platform/package-summary#LocalInspectionMode()|https://developer.android.com/reference/kotlin/androidx/compose/ui/platform/package-summary#LocalInspectionMode()>

it's Android-only at the moment, but see no reason not to have it on other platforms as well

I wonder what’s your usecase? I don’t see a reason against it, but I have not thought anyone needs that before today :slightly_smiling_face:
Also feel free to create an issue at   <https://github.com/JetBrains/compose-jb/issues>

I am not saying it's a _good_ use-case, but I have a view that is using my service locator as part of rendering, and I suspect (am not sure) that this is causing the previewer to fail since it'd require the rest of the application running to instantiate that.

This is for a hobby project so I'm playing looser with the rules than I would for a work application :slightly_smiling_face:

(deleted some irrelevant info, I had to restart IntelliJ to get the Previewer working again)

Just confirmed via commenting out and back in that using my service locator while rendering causes previewing to fail.
All it's doing is resolving to a boolean, so I'd like to, in Preview mode, hardcode the boolean rather than using the SL.

```            if (!modVariant.mod(SL.access).isEnabled(modVariant)) {
                SmolButton(
                    modifier = Modifier
                        .padding(top = 4.dp)
                        .align(Alignment.CenterHorizontally),
                    onClick = {
                        GlobalScope.launch { SL.access.enableModVariant(modVariant) }
                    }
                ) {
                    Text("Enable")
                }
            }```
is the part that, when commented out, allows the Previewer to work.

I think you can create a @Preview wrapper for your actual Composable and pass the parameter from there. It looks simple and much more explicit
