Jetpack Compose 容器在哪里?

Ely*_*lye 3 android android-jetpack-compose

我从一些教程中阅读了容器

它的编码如下

@Composable
fun Container(
    modifier: Modifier = Modifier.None,
    padding: EdgeInsets = EdgeInsets(0.dp),
    alignment: Alignment = Alignment.Center,
    expanded: Boolean = false,
    constraints: DpConstraints = DpConstraints(),
    width: Dp? = null,
    height: Dp? = null,
    children: @Composable() () -> Unit
)

最近在 Jetpack Compose 上探索的时候1.0.0-alpha07,看不到了。它不再受支持还是我错过了什么?

我包括了所有我能想到的图书馆,但它没有显示。

    implementation 'androidx.compose.ui:ui:1.0.0-alpha07'
    // Tooling support (Previews, etc.)
    implementation 'androidx.ui:ui-tooling:1.0.0-alpha07'
    // Foundation (Border, Background, Box, Image, Scroll, shapes, animations, etc.)
    implementation 'androidx.compose.foundation:foundation:1.0.0-alpha07'
    // Material Design
    implementation 'androidx.compose.material:material:1.0.0-alpha07'
    // Material design icons
    implementation 'androidx.compose.material:material-icons-core:1.0.0-alpha07'
    implementation 'androidx.compose.material:material-icons-extended:1.0.0-alpha07'
    // Integration with observables
    implementation 'androidx.compose.runtime:runtime-livedata:1.0.0-alpha07'
    implementation 'androidx.compose.runtime:runtime-rxjava2:1.0.0-alpha07'

你好容器已被删除。您可以改用Box

androidx.ui: ui - *: 在 0.1.0-dev11 版本中删除。
