@monsif - Please double check your app.module.ts file "Providers" section whether "FCM" added.

For example:

import { FCM } from '@ionic-native/fcm';

providers: [ StatusBar, SplashScreen, {provide: ErrorHandler, useClass: IonicErrorHandler}, FCM
]

@shivsuthanmhub yes i do have FCM in providers:

  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    AuthService,
    MarkersService,
    Facebook,
    Geolocation,
    Camera,
    File,
    FCM,
    Properties,
    Diagnostic,
    PermissionsService
  ]
