Jetpack 组合前瞻范围

Question

我正在尝试实现 LazyVerticalGrid 和 Column 可组合项之间的共享元素转换

SceneHost(modifier = Modifier.fillMaxSize()) {
        if (isTransformed.value) {
            Column(
                modifier = Modifier.fillMaxSize(),
                verticalArrangement = Arrangement.Center,
                horizontalAlignment = Alignment.CenterHorizontally
            ) {
                movableItems(selectedIndex.value) {
                }

            }
        } else {
            LazyVerticalGrid(
                columns = GridCells.Fixed(4),
                state = state
                //modifier = Modifier.fillMaxSize()
            ) {
                items(
                    key = { colors[it].value.toString() },
                    count = colors.size,
                    itemContent = { index ->
                        movableItems(index) {
                        }

                    })
            }
        }
    }

SceneHost 是 LookaheadScope 的包装器，它是从 LookaheadScope 示例中克隆的

这是网格的样子

具有扩展尺寸的元素不会转换并抛出

这里是过渡

并且元素没有从它们的坐标开始转换
