What is the difference between ion-native and ion-ion native / xxx in ionic 2

Question

I am trying to use the Ionic Native feature in my Ionic2 application. I find a significant number of examples and installation instructions for the ion-native module node, as well as for @ ionic-native / [package-name]. I don’t understand which node module to use. It seems like ion-native is being installed, but all documentation at https://ionicframework.com/docs/native/ uses @ ionic-native / [package name]. What is the difference between these two packages? What should be used in my ionic2 application?

Below is my current project information.
