"For now, you can only add a component in a details view" On Classic Apps

Two things:

  1. You have to change your screen layout from a list style layout to a detail style layout. This is how it works on Classic Apps. In New Apps, all screens are detail style layout screens.
  2. That incarnation of barcode scanning is formally deprecated. You can use it if you currently have it, but you can’t add it.

Also, Classic Apps WILL eventually go away, so don’t put too much effort into building new projects with them.
