              ShoppingCartScreen(

  `Snabble.checkedInProject`

### Important note
`Snabble.checkedInProject` uses `LiveData` with a slightly modification: All changes will be directly applied so
that `getValue()` will return always the latest data no matter on which thread set. The changes will be propagated as
expected normal on the UI-Thread. You can also use a new `value` property in Kotlin.
