How to share data between menu and page in split-pane?

I have the following split-pane:

I would like to show on the pane page the info of the trip selected on the list.

I choose which page to show assigning the root property of the split-pane nav
root = TripPage

How can I send the object info to that page?

When I don’t use the split pane, I usually do something like this:

this.navCtrl.push(TripPage, {
      data: this.trip
