Observable.fromEvent is not a function error after updating ionic-native to 4.10.0

ionic-image-loader throws Observable.fromEvent is not a function error after updating ionic-native to 4.10.0. Issue occurs on this line: r.is("cordova") ? o.Observable.fromEvent(document, "deviceready").first().subscribe(function(t) { i.nativeAvailable ? i.initCache() : (i.isInit = !0, i.throwWarning("You are running on a browser or using livereload, IonicImageLoader will not function, falling back to browser loading.")) }) : (this.isInit = !0, this.throwWarning("You are running on a browser or using livereload, IonicImageLoader will not function, falling back to browser loading."))

The issue happens when you have installed rxjs version 6+ On angular 6 or by installing the dependency manually, this will occur.

To temporarily fix it, I’ve cloned the repo, and edited the file providers/image-loader.ts.

Replacing: import { Observable } from 'rxjs/Observable'; to: import { Observable, fromEvent } from 'rxjs';

On line 6. And, replacing: Observable.fromEvent(document, 'deviceready').first().subscribe(res => { to: fromEvent(document, 'deviceready').first().subscribe(function (res) { on line 67

I made the temporarily workaround until the repo gets updated. I can send an pull request too if the devs are interested.

I will update the repository and its dependency soon to reflect the latest rxjs changes.
