FileTransfer is not defined in ionic 1.3.2

Hi everyone,

I know this issue has already been debated here on the ionic forum but I can’t solve the following issue :

ReferenceError: FileTransfer is not defined

I’m using the last version of ionic : 1.3.2 and cordova version 4.2.0
I added both file and file-transfer plugins using the following commands:

ionic plugin add org.apache.cordova.file-transfer
ionic plugin add org.apache.cordova.file

and I, of course, built the project using ionic build

but I still can’t manage to make this work even with a sample code.
Each time I access the plugin I get this error.
I tried to start multiple other projects but without any success.

Do you have any solution to that problem ?
