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

Send data with Router service and extract with global variable, history

//sender component

  // private router: Router
  nextPage() {
    this.router.navigate(['history'],
      { state: [{ name: "covid-19", origin: "china" },{ name: "ebola", origin: "us" }] }
    )
  }

//receiver page

  ngOnInit() {
  let data = history.state;
  console.log("data-->",data);
// ** data** 
//0:{name: "covid-19", origin: "china"} 1: {name: "ebola", origin: "us"} navigationId: 2
  }
