Why passing ```content: @Composable ColumnScope.() -> Unit``` in ```content: @Composable () ->...

# compose

[Michał Diner]

Why passing

content: @Composable ColumnScope.() -> Unit

in

content: @Composable () -> Unit

and invoking it in

AnimatedVisibility(...) {
   content()
}

Cancels the ColumnScope?

[Doris Liu]

That's because AnimatedVisibility is a Layout itself. Therefore when content gets put in the AnimatedVisibility, it's no longer a direct child of Column . Therefore ColumnScope extensions will have no effect on content.
