How to get current page from Navigation in ionic 2

I am new to Ionic2, and I am trying to build dynamic tabs based on current menu selection. I am just wondering how can I get current page using navigation controller.

...
export class TabsPage {
  constructor(navParams: NavParams,navCtrl:NavController) {
    //here I want to get current page
 }
}
...

From api documentation I feel getActiveChildNav() or getActive() will give me the current page, but I have no knowledge on ViewController/Nav.

Any help will be appreciated. Thanks in advance.

Full example:

import { NavController } from 'ionic-angular';

export class Page {

  constructor(public navCtrl:NavController) {
  }

  (...)

  getActivePage(): string {
    return this.navCtrl.getActive().name;
  }
}

Method to get current page name:

this.navCtrl.getActive().name
