Ionic2 filetransfer - No provider for Transfer - ionic-framework

Question

I'm trying to use filetransfer as a provider in my app, but I'm getting this problem.
"No provider for Transfer!"
I can't find the solution.
This is my code.
My provider
import { Injectable } from '#angular/core';
import { Transfer, FileUploadOptions, TransferObject } from '#ionic-native/transfer';
// import { File } from '#ionic-native/file';
#Injectable()
export class FileTransfer {
options: FileUploadOptions = {}
fileTransfer: any;
constructor(private transfer: Transfer) {
console.log('Hello FileTransfer Provider');
}
I already imported my provider to the app.module
import { NgModule, ErrorHandler } from '#angular/core';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { FileTransfer } from "../providers/file-transfer";
And added it to my providers in the same app.module
providers: [{ provide: ErrorHandler, useClass: IonicErrorHandler }, Storage, FileTransfer]
And finally, I'm importing the provider to my page.
import { Component } from '#angular/core';
import { FileTransfer } from '../../providers/file-transfer';
----
constructor(
public navCtrl: NavController,
public navParams: NavParams,
public storage: Storage,
public platform: Platform,
public alertCtrl: AlertController,
public modal: ModalController,
public loadingCtrl: LoadingController,
public fileTransfer: FileTransfer
)
So i dont know, where the problem is, I hope, you can help me.
Thanks!!

Answer 1

Try:
import { Transfer } from "../providers/file-transfer";
in your app.module.
And,
providers: [{ provide: ErrorHandler, useClass: IonicErrorHandler }, Storage, Transfer]
in your providers.

Answer 2

The error is
"No provider for Transfer!"
Your import syntax is for ionic-native 2.8.1 here.
Change import to
import { Transfer} from '#ionic-native';
Or change ionic-native version to 2.8.1.
