Expected 1 arguments when using storage in ionic

I tried using local storage in my ionic service provider app but I got this error.

[ts] Expected 1 arguments, but got 0. (alias) new Storage(config:
StorageConfig): Storage import Storage Create a new Storage instance
using the order of drivers and any additional config options to pass
to LocalForage.

Possible driver options are: ['sqlite', 'indexeddb', 'websql',
'localstorage'] and the default is that exact ordering.

Here is my source code:

import Storage from '@ionic/storage';

@Injectable()
export class MyServiceProvider
public local : Storage;
mydata: any;


constructor(public http: Http)
this.local = new Storage()


postLogin(data)
let link = "http://myapi.com/api/login.php";
return this.http.post(link, data)
.map(data =>
this.mydata = data;
console.log("data")
, error =>
console.log(error)
)

I didn't understand well what you want to do with the Storage, but according to Ionic Storage docs, you need to inject into your provider/component.

import Storage from '@ionic/storage';

export class MyApp
constructor(private storage: Storage)



I suggest you to use that provider do get and set the data and you can call these methods wherever you import your provider.

public setData(nameData: string, valueData: any)
this.storage.set(nameData, valueData);


public getDataValue(nameData: string)
return this.storage.get(nameData);
