is it possible to import an annotation depending on the platform? for example 
androidx.compose.ui.tooling.preview.Preview
for 
Android
androidx.compose.desktop.ui.tooling.preview.Preview
for 
Desktop
CommonMain
use 
@Preview
which resolves to the above at compilation/analysis

you can create you own annotation with 
expect
and then have `typealias`’s the 
actual
annotation.
k
o.o
can you give an example please?
c
commonMain
Copy code
@Target(AnnotationTarget.FUNCTION)
expect annotation class CommonPreview()
androidMain
Copy code
actual typealias CommonPreview = androidx.compose.ui.tooling.preview.Preview
jvmMain
Copy code
actual typealias CommonPreview = androidx.compose.desktop.ui.tooling.preview.Preview
k
o.o awesome
thanks
if i have
Copy code
import androidx.compose.desktop.ui.tooling.preview.Preview
import androidx.compose.runtime.Composable

actual typealias CommonPreview = androidx.compose.desktop.ui.tooling.preview.Preview
can i use 
actual typealias CommonPreview = Preview
c

e: C:\Users\clark\IdeaProjects\LuaJIT_Kotlin_MultiPlatform\common\src\commonMain\kotlin\smallville7123\lua\jit\kotlin\common\App.kt: (18, 44): Expecting a top level declaration
Copy code
@Target(AnnotationTarget.FUNCTION)
expect annotation class CommonPreview() as Preview
c
Remove the 
as Preview
- that’s what you want to avoid.
k
yea
