ObservableMedia replaced by MediaObserver from @angular/flex-layout v7.0.0-beta.24 (2019-03-17)

Before:

import {MediaChange, ObservableMedia} from "@angular/flex-layout"; constructor(public media: ObservableMedia) {}

After:

import {MediaChange, MediaObserver} from "@angular/flex-layout";
constructor(public media: MediaObserver) {}

In flex-layout versions 7.0.0-beta.20 and higher ObservableMedia was replaced with MediaObserver.

media-observer: ObservableMedia is now deprecated in anticipation of RxJS v7. The new API is called MediaObserver, and provides the exact same functionality as ObservableMedia, except you cannot directly subscribe to it,

Developers should subscribe to MediaObserver's media$ property; in place of subscribing directly to ObservableMedia. - quoted from https://github.com/angular/flex-layout/blob/master/CHANGELOG.md

After I made that change, it worked with no issues on the latest versions as of today:

"@angular/core": "^7.1.1",
"@angular/flex-layout": "^7.0.0-beta.23",
"rxjs": "^6.3.3",
"rxjs-compat": "^6.3.3"

Try adding this to your imports at the top of your app.module.ts file:

import { FlexLayoutModule } from '@angular/flex-layout';

And add this into your imports array within the @NgModule of your app.module.ts file:

FlexLayoutModule
