I'm using Jetpack Compose for the first time but I'm getting this error. I haven't figured out where the problem really is but I'm using single-activity architecture. If more information is needed, kindly inform me. According to the error, the problem seems to be coming from the Scaffold.
val scaffoldState = rememberScaffoldState()
Scaffold(
scaffoldState = scaffoldState,
snackbarHost = {
SnackbarHost(hostState = it)
}
) {
java.lang.NoSuchFieldError: No field Companion of type Landroidx/compose/foundation/layout/BoxScope$Companion; in class Landroidx/compose/foundation/layout/BoxScope; or its superclasses (declaration of 'androidx.compose.foundation.layout.BoxScope' appears in /data/app/com.octagon_technologies.scafe-0B8-dDpbnRqa6fydxFPekw==/base.apk)

This answer is based on CommonsWare comment which helped me fix the error.
The solution was to use a consistent set of Compose dependencies. beta04 made a change to BoxScope in the compose-foundation artifact. Perhaps you are getting beta04 of that artifact but are getting an older compose-material artifact.
