NavParams / Providers Issues in Ionic 2 BETA

Ionic Framework ionic-v3
2

you only get the navcontroller via @ViewChild decorator.

NavParams is a simple service you can inject via dependency injection:

import {Component} from '@angular/core';
import {NavParams} from 'ionic-angular';

@Component({...})
export MyComponent {
  constructor(private params: NavParams) {
    console.log(this.params);
  }
}
