passing parameter between pages ionic - ionic-framework

Question

Hi i´m new in ionic and I am trying to pass the scann information form one page to another, the thing its that when I execute the program I have a console.log to check if the info its passed correctly but on chrome console said undefined, letme paste my code:
home.ts where i try to send the info from the scan:
import { Component } from '#angular/core';
import { NavController,Platform } from 'ionic-angular';
import { BarcodeScanner } from '#ionic-native/barcode-scanner';
import { TabsPage } from '../tabs/tabs';
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
private barcodeText:String;
private barcodeFormat:String;
private platform:Platform;
private navController:NavController;
constructor(private barcodeScanner: BarcodeScanner,public navCtrl: NavController,platform:Platform) {
this.platform = platform;
this.navController = navCtrl;
}
doScan(){
console.log('scannig product barcode');
this.platform.ready().then(() => {
this.barcodeScanner.scan().then((result) => {
if (!result.cancelled) {
this.barcodeText = result.text;
this.scanningDone(this.barcodeText)
}
}, (error) => {
console.log('error when scanning product barcode');
});
});
}
scanningDone(data){
this.navController.push(TabsPage,{
data:data
});
}
main.ts where the info suppose to go:
import { Component } from '#angular/core';
import { NavController, NavParams , ToastController} from 'ionic-angular';
import { BarcodeScanner } from '#ionic-native/barcode-scanner';
import { DetailsPage } from '../details/details';
import { Http } from '#angular/http'
#Component({
selector: 'main',
templateUrl: 'main.html'
})
export class MainPage {
information: any[];
item:any;
private bcData;
constructor(public navCtrl: NavController, private http: Http,public params:NavParams) {
this.bcData = params.get('data');
console.log(params.get('data'));
let localData = http.get(this.bcData).map(res => res.json().items);
localData.subscribe(data => {
this.information = data;
})
}
on the console.log(params.get('data')); its where I get the undefinied on the console.

Answer 1

you could have a method in your TabsPage that handles opening and closing pages like this:
openPages(Page, Data){
this.navCtrl.push(Page,Data);
}
Then in your scanningDone Method:
scanningDone(data){
this.tabsPage.openPages(MainPage,{
data:data
});
}

Answer 2

How about using localStorage
