Hello, im trying to have a AnimatedVisiblity composable inside a Box, which is nested inside a Column like this:

Column {
        Box {
           AnimatedVisibility(visible = true) {
               Text("test")
           }
        }
    }

This results into an error:
'fun ColumnScope.AnimatedVisibility(visible: Boolean, modifier: Modifier = ..., enter: EnterTransition = ..., exit: ExitTransition = ..., label: String = ..., content: AnimatedVisibilityScope.() -> Unit): Unit' can't be called in this context by implicit receiver. Use the explicit one if necessary
The provided fix from IDE is to annotate the AnimatedVisibility with

Column {
        Box {
            [e-mail](visible = true) {
                Text("test")
            }
        }
    }

Then everything works fine. The question is why is this necessary? Is this the correct fix? Why cant I call this composable like every other composable?

It looks like it's using/importing the wrong function, which expects a receiver of type ColumnScope .

The "normal" function: https://developer.android.com/reference/kotlin/androidx/compose/animation/package-summary#AnimatedVisibility(kotlin.B[…]lin.String,kotlin.Function1)
The column scope extension function: https://developer.android.com/reference/kotlin/androidx/compose/animation/package-summary#(androidx.compose.foundatio[…]lin.String,kotlin.Function1)

AnimatedVisibility inside a box should probably use the non-extension function. Make sure to select the correct AnimatedVisibility function when using autocomplete, although I believe it should automatically pick the correct one.

This is a Kotlin issue and no, your code is not the correct fix as ColumnScope is not actually accessible there. The AnimatedVisibility function without a receiver is what you should use. You can extract the AnimatedVisibility to a new function. Using the fully qualified name androidx.compose.animation.AnimatedVisibility also seems to fix the problem.

thanks for the support! 🙂
will fix temporary with fully qualified name
