(jetpack compose) androidx.compose.runtime.internal.ComposableLambdaImpl 无法转换为 kotlin.jvm.functions.Function0

Question

我有一个用于自定义视图的 BaseUi 类，我的活动从它扩展。
当我使用Root函数时，应用程序崩溃了。

BaseUi.kt

@ExperimentalAnimationApi
open class BaseUi : AppCompatActivity() {

@Composable
fun RtlView(content: @Composable () -> Unit) {
    CompositionLocalProvider(
        LocalLayoutDirection provides LayoutDirection.Rtl,
        content = content
    )
}

@Composable
fun LtrView(content: @Composable () -> Unit) {
    CompositionLocalProvider(LocalLayoutDirection provides LayoutDirection.Ltr) {
        content()
    }
}

@Composable
fun Root(
    content: @Composable () -> Unit
) {
    KasbTheme {
        Box(
            Modifier
                .fillMaxSize()
                .background(LightPageBackground)
                .padding(Dimen.pagePadding)
        ){
            content()
        }
    }
}
}

SplashActivity.kt

@ExperimentalAnimationApi
class SplashActivity : BaseActivity() {

val viewModel = SplashActivityViewModel()

@ExperimentalAnimationApi
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
        InitUI()
    }
}

@ExperimentalAnimationApi
@Preview(showBackground = true)
@Composable
fun InitUI() {
    Root {
        RtlView {
            Box(Modifier.fillMaxSize()) {
                Image(
                    painter = painterResource(id = R.drawable.logo),
                    contentDescription = "",
                    modifier = Modifier.size(200.dp).align(Alignment.Center)
                )
            }
        }
    }
}
}

运行时错误

这不是永久修复，但干净的项目消除了一次编译的错误。但不知道为什么会这样。
