Unable to associate with 'ngIF' as it is not recognized as a valid property of 'ion-item'

I am facing a challenge in implementing *ngIF within the code of my Ionic4 project. I have come across some solutions, but none seem to be compatible with ionic 4 and angular 7.

I attempted to import the imports: [CommonModule] part, but unfortunately, it did not work at all.

Below is the snippet of the code I am using in the .html file:

<ion-app>
    <ion-split-pane>
        <ion-menu>
            <!-- Rest of the HTML code provided here -->
        </ion-menu>
        <ion-router-outlet main></ion-router-outlet>
    </ion-split-pane>
</ion-app>

In addition, this is the code present in my .ts file:

import {Component} from '@angular/core';
// Other imports mentioned here

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['main.scss'],
})
export class AppComponent {

    // Constructor function and array declaration here

    initializeApp() {
        // Initialization code inside this function
    }

    authenticatedState() {
        return this.authService.authenticated();
    }
}

The issue arises when trying to utilize *ngIf which calls a function linked to a service returning either True or False.

The specific error message encountered reads as follows:

Can't bind to 'ngIF' since it isn't a known property of 'ion-item'

Answer №1

It is important to use *ngIf instead of *ngIF. Make sure to refer to the documentation for a detailed explanation on structural directives: https://angular.io/guide/structural-directives

<ion-item routerLink='/login' *ngIf='checkAuthenticated()'>
