This recipe is quite similar to the previous two, but here, we used DELETE, a verb that's conventionally used when an app asks the web server to delete an existing piece of data.
This is why we had to instruct our mock web service to accept a DELETE at the /pizza address – so that we could try sending some data to it and it would respond with a success message.
After creating the delete stub in MockLab, we created the deletePizza method, which works just like the postPizza and putPizza methods; it just needs the ID of the pizza to delete it.
To make the user delete an existing Pizza, we used the Dismissible widget, which is used when you want to swipe an element (left or right) to remove it from the screen.
