How to use getRootNavById?

Ionic Framework ionic-v3
1

can anyone help me with examples of how to use getRootNavById?

2

What are you trying to achieve?

3

I have 3 pages
page1
page2
page3

currently to send:
this.app.getRootNav (). setRoot (page2, {data: this.getData});

but get message from: (getRootNav) is deprecated and will be removed in the next major release. Use getRootNavById instead.

so I want to know how to go from page1 to page2 with getRootNavById.

Typically one would just inject a NavController in page1 and call its push() method with page2 and whatever extra parameters are required. That’s the flow users will be expecting.

If i’m inside of a tab and i want to set root another page calling a function… what’s the proper way to achieve this?

Actually i use this:

this.app.getRootNav().setRoot(OfflinePage,{text: '505'});

ok so I got this going for now, but…
if they change the id, Im in deep doo, doo.

first i did…

console.log(this.app.getRootNav().id);

and got -

n4

n4 scares me

so i did

let newRootNav = <NavController>this.app.getRootNavById('n4');
    newRootNav.push(DrugCardEmailPage,{...}

this works but if they change the name, and we loose getRootNav().id

aaaah…

please don’t remove this capability, Ioinc Team
