Can't resolve all parameters - ToastController (beta11)

Ionic Framework ionic-v3
1

I’ve just installed version beta11 to use the ToastController.

But I get this exception:

browser_adapter.js:77 ORIGINAL EXCEPTION: Can't resolve all parameters for LoginComponent: (Platform, NavController, UserService, ?).

My code:

import { Component, ViewChild } from '@angular/core';
import { NavController, Nav, Platform, ToastController } from 'ionic-angular';
import { Router } from '@angular/router';
//import { FacebookLoginService } from '../../../services/fblogin.service.ts';
import { Toast } from 'ionic-native';
import { UserService } from '../../../services/user.service';
import { ActivitiesComponent } from '../activities/activities.component';


@Component({
  templateUrl: 'build/pages/login/login.html'
})
export class LoginComponent {

  constructor(
    private platform: Platform,
    private nav: NavController,
    private userService: UserService,
    private toastController: ToastController) {}

}

Could you provide any more info?

Not a whole lot there, and I’m unable to replicate this with a blank project.

Could you try to create a small demo and post a git repo here?
