NavController doesn't work in Ionic 4

Question

I'm injecting NavController in my constructor as I want to push a page. But, below code doesn't work in Ionic 4. It was totally okay in Ionic 3.

Constructor

constructor(public menuCtrl: MenuController, public navCtrl: NavController) {
    this.menuCtrl.enable(true);
   }

Method

goToSecondPage()
  {
    this.navCtrl.push(list);
  }

Now, to complete the final step and implement those routes in our app-routing.module.ts file, they would look like this:

const routes: Routes = [
{ path: '', redirectTo: '/home', pathMatch: 'full' },
{ path: 'home', loadChildren: './pages/home/home.module#HomeModule' },
{ path: 'products', loadChildren: './pages/products/products.module#ProductsModule'},
{ path: 'products/:id', loadChildren: './pages/product-detail/product-detail.module#ProductDetailModule' },
{ path: 'products/categories', loadChildren: './pages/product-categories/product-categories.
{ path: 'support', loadChildren: './pages/support/support.module#SupportModule' }
];

setRoot in html page

<ion-button href="/support" routerDirection="root">

or in class

this.navCtrl.navigateRoot('/support');

Push

<ion-button href="/products/12" routerDirection="forward">

or

this.navCtrl.navigateForward('/products/12');

Pop

<ion-button href="/products" routerDirection="backward">

or

<ion-back-button defaultHref="/products"></ion-back-button>

you can also navigate backwards programatically:

this.navCtrl.navigateBack('/products');
