Native transfer plugin - not available after install in ionic2

I have installed native TRANSFER plugin in my ionic 2 app in 2 steps:
1. ionic plugin add cordova-plugin-file-transfer
2. npm install --save @ionic-native/transfer

After that i imported the plugin in my home.ts page.
import { Transfer } from ‘@ionic-native/transfer’

I tried to use the plugin to upload a file
var ft = new Transfer();

But i can’t use ft var, because Transfer plugin look like it’s not avalable.
If i write ft.upload () i receive an error like: Property ‘upload’ does not exist on type ‘Transfer’.

My technologies:
Cordova CLI: 6.4.0
Ionic Framework Version: 2.3.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.1.4

In the previous version of my app when using Ionic Framework Version: 2.0.0-rc.5 /Ionic App Scripts Version: 1.0.0 all worked just fine.

Does anyone has any solution for this?
Thanks in advance.

You need to follow the instructions here:

I used the solution suggested here and it worked.

What it says in Stackoverflow, is the same as it says in the documentation and which our friend @ihadeed recommended in the link, we should read the documentation well to avoid those headaches. :+1:
