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');
