Jetpack Compose 中的动画重组（视图更改）

Question

Is there a way to automatically animate composition changes in a Jetpack Compose @Composable ? For instance, if a previously shown widget is removed in a recomposition, can a fade-out animation be applied automatically? I'm thinking something similar to Android View 's animateLayoutChanges .

Answer 1

Yes, you can use:

val visible by remember { mutableStateOf(false) }
AnimatedVisibility(visible = visible) {
    // Composables Here 
}

Answer 2

Or for the specific animation you asked for, surround the Composable (s) with CrossFade
