disable menu on login page ionic 4

Ionic 4 you would use the disabled property on ion-menu to hide on login.

<ion-menu [disabled]="!isLoggedIn"></ion-menu>

Ionic 6 still supports ionViewWillEnter, use below code:

ionViewWillEnter() {
  this.menuCtrl.enable(false);
}

You can find full example here.

In my case in ionic 4 app, I did the following in welcome.page.ts file. welcome.page.ts is the page in which I want to hide split pane.

import {  MenuController } from '@ionic/angular';

constructor( public menuCtrl: MenuController){}

ionViewWillEnter() {
 this.menuCtrl.enable(false);
}
