Question

I tried passing parameters in push method of ionic2. like this

this.nav.push(SecondPage, {
    thing1: data1,
    thing2: data2
});

but is ther

Answer 1

This is how I achieved it in ionic-3 and find it easier.

Page from where we pop()

 this.navCtrl.getPrevious().data.thing1 =data1;
 this.navCtrl.getPrevious().data.thing2 =data2;
 this.navCtrl.pop();

Page after pop():

public ionViewWillEnter() {
     this.thing1 = this.navParams.get('thing1')|| null;
     this.thing2 = this.navParams.get('thing2')|| null;
}
