Navigation From one form to another is not working

I’m trying to navigate, after login submit event…I didn’t able to find out why my navigation is not working …Can anyone help me out…Thanks in Advance…Here is IonicFrontEnd and WebAPIBackEnd

Please focus on

OnSubmit(userName,password){
     this.userService.userAuthentication...........
     ....................................................................;
      this.router.navigate(['/home']);
      
    },

of pages/login/login.ts

this.router.navigate([’/home’]); this line is not working…

this.navCtrl.push(HomeComponent);
Tried with above line, inplace of this.router.navigate([’/home’]); line.

Now working proper. I need to import NavController from ‘ionic-angular’ and I should use it in Constructor
