I’m currently using Ionic4 and what I’m trying to do is a very basic task (I’m new to this and I’m trying to learn). Basically what I’m trying to do is:
use a Modal page to create a ‘contact’
Save that contact’s info into an array ( contact.name, contact.phoneNumber, etc)
retrieve that data in another page and present it in a list
I’ve tried to follow a few tutorials but they all use Ionic 3 and require ViewController or NavParams which have been deprecated to my knowledge.
I would suggest going through the Tour of Heroes, paying especially close attention to chapter 4 about services. That entire tutorial builds out an app very similar to what you describe.
