getRootNav() deprecated, use getRootNavById(): what's the value of the root nav id?

[rflorat07]

You can use this this.app.getRootNavs()[0] because getRootNav() is

getRootNav(): any {
const rootNavs = this.getRootNavs();
if (rootNavs.length === 0) {
return null;
} else if (rootNavs.length > 1) {
console.warn(’(getRootNav) there are multiple root navs, use getRootNavs instead’);
}
return rootNavs[0];
}

import { App } from ‘ionic-angular’;

rootNavCtrl: NavController;

constructor( private app: App ) {}

this.rootNavCtrl = this.app.getRootNavs()[0]
