在Compose 1.2.0-alpha08 以前，可以使用以下代码

val dialog = Dialog(context)
dialog.window?.decorView?.apply {
    ViewTreeLifecycleOwner.set(this, this@MainActivity)
    ViewTreeViewModelStoreOwner.set(this, this@MainActivity)
    ViewTreeSavedStateRegistryOwner.set(this, this@MainActivity)
    }

在Compose 1.2.0-alpha08以后，ViewTreeSavedStateRegistryOwner的API发生了变更

val dialog = BottomSheetDialog(this@MainActivity)
dialog.window?.decorView?.apply {
    ViewTreeLifecycleOwner.set(this, this@MainActivity)
    ViewTreeViewModelStoreOwner.set(this, this@MainActivity)
    setViewTreeSavedStateRegistryOwner(this@MainActivity)
    }
