Hi , does anyone know why println("hello") will not be called if there is a composable inside the ?.let{}

val name: String? = null

      Box() {

Seems to be a bug, see thread for workarounds.

[Jean-Luc D.]

xx?.let { } ?: is not always the same as if (xx != null) { } else { } the return value of let is the return value of the lambda. In your case, the Box statement. Since it doesn't return null, the print statement will never be executed.
