In which task and step of the codelab can this issue be found?

In the ItemDetailsViewModel class, set outOfStock value based on the it.quantity in the map transformation.
Describe the problem
first, ItemDetailsUiState(outOfStock = it.quantity > 0,itemDetails = it.toItemDetails()) should be used to replace ==== ItemDetailsUiState(outOfStock = it.quantity <= 0, itemDetails = it.toItemDetails())

then in the ItemDetailsScreen file, in the ItemDetailsBody composable, for the "Sell" button, I think we should assign the enabled parameter with this arguement : itemDetailsUiState.outOfStock instead of a true value so the button is disabled when on stack is false. Meaning, quantity is less than or equals to 0.
