我是第一次使用 Jetpack Compose，但出现此错误。我还没有弄清楚问题到底出在哪里，但我使用的是单一活动架构。如果需要更多信息，请通知我。根据错误，问题似乎来自 Scaffold。

                val scaffoldState = rememberScaffoldState()

                Scaffold(
                    scaffoldState = scaffoldState,
                    snackbarHost = {
                        SnackbarHost(hostState = it)
                    }
                ) {

staticCompositionLocalOf我正在尝试根据Medium 上的这篇文章在 Jetpack Compose 中使用。这是我的 ProvidableCompositionLocal

val lightColors = lightColors(
    primary = LightColor.BackgroundWhite,
    primaryVariant = LightColor.ToolbarWhite,
    secondary = LightColor.FabBlue,
