rootParams in ion-nav not working

Ionic Framework ionic-v3
1

Hi I tried to pass data in ion-nav using rootParams.

Example:
<ion-nav [root]="rootPage" [rootParams]="paramData"></ion-nav>

this.paramData = {data: ‘Testing’};

Getting Data:
navParams.get(‘data’); --> returns nothing.

How can I make it work?Thanks.

This is still an issue but a workaround is available.
