Ionic 4. Alternative to NavParams

Question

I am using ionic 4. It does not accept to receive data using navparams. Here is my sender page method:

  //private route:Router
  gotoFinalView(intent) {
            


        

Answer 1

The item, icon and title variables you want to send should be written in the state in this way.

this.nav.navigateForward('/myUrl', {
        state: {
          'items': this.substances,
          'icon': ICONS.substance,
          'title': 'Etken Maddeler'
        }
      });

We take incoming variables this way.

//receive
constructor(
      protected route: ActivatedRoute,
      protected router: Router,
  ) {
    this.selectedItem = null;
    this.route.paramMap.subscribe(params => {
      let st = this.router.getCurrentNavigation().extras.state;
      if (st) {
        this.selectedItem = st.items;
      }
    });
  }
