FabricPlugin and Ionic3

[pertoft]

I have followed the guide at the official Ionic documentaiton: https://ionicframework.com/docs/v3/native/crashlytics/

ionic cordova plugin add cordova-fabric-plugin --variable FABRIC_API_KEY=XXX --variable FABRIC_API_SECRET=xxx
npm install --save @ionic-native/fabric

In app.module.ts:
...
import { Crashlytics } from '@ionic-native/fabric';
...
providers: [
Crashlytics,
StatusBar,
SplashScreen,
...

VS Code gives the error:

Build error:

Have I missed something or is there a bug here?
