我正在使用 jetpack compose 1.0.0，BottomSheetScaffold 工作正常，但是在我添加了一个功能来使用按钮将主题从浅色更改为深色后，在更改主题后，底部工作表将不会展开。我正在使用 Application 类的属性来处理主题状态。这是一些代码：

使用底部工作表的屏幕，顺便说一句，这是在片段上

MyAppTheme(application.isDark.value) {

    val bottomSheetScaffoldState = rememberBottomSheetScaffoldState(
        bottomSheetState = BottomSheetState(BottomSheetValue.Collapsed)
    )
    val coroutineScope = rememberCoroutineScope()

    BottomSheetScaffold(
        scaffoldState = bottomSheetScaffoldState,
        sheetContent = {
            HomeBottomSheet(
                onCancelClick = {
                    coroutineScope.launch {
                        bottomSheetScaffoldState.bottomSheetState.collapse()
                    }
                },
                onDoneClick = { text ->
                    Toast.makeText(requireContext(), text, Toast.LENGTH_LONG)
                        .show()
                }
            )
        },
        sheetPeekHeight = 0.dp
    ) {
        HomeScreen(
            darkTheme = application.isDark.value,
            darkThemeToggleClick = application::toggleDarkTheme,
            onHistoryClick = {
                findNavController().navigate(R.id.goToHistory)
            },
            onAddClick = {
                coroutineScope.launch {
                    bottomSheetScaffoldState.bottomSheetState.expand()
                }
            }
        )
    }
}

应用：
