Ionic 4 pass property to custom component - ionic-framework

Question

I've written a custom component to handle my ion-header as all I need to change per page is the title. However, the title is not displaying as the component doesn't seem to be getting the property from the app page.
Component Template
<ion-header>
<ion-toolbar color="primary">
<ion-buttons slot="start">
<ion-menu-button></ion-menu-button>
</ion-buttons>
<ion-title> {{title}} </ion-title>
Component Typescript
import { Component, OnInit, Input } from '#angular/core';
#Component({
selector: 'app-custom-toolbar',
templateUrl: './custom-toolbar.component.html',
styleUrls: ['./custom-toolbar.component.scss'],
})
export class CustomToolbarComponent implements OnInit {
#Input() title: any;
constructor() { }
ngOnInit() {
}
}
App Page Template
<app-custom-toolbar [title]="Dashboard"></app-custom-toolbar>

Answer 1

You need to declare #Input() title in your custom component to pass value from parent into it like -
Child Component
...
...
#Input() title: any;
...
...
Parent Component HTML -
<child-component [title]="somePropertyInParentComponent"></child-component>
Edit: According to your updated question . Try removing [] from the title property in parent component

As Pawan Sharma says, you need to declare an #Input,
In this link you can find more information about it.

Typescript
import { Component, OnInit, Input } from '#angular/core';
import { NavController } from '#ionic/angular';
#Component({
selector: 'app-footertoolbar',
templateUrl: './footertoolbar.page.html',
})
export class FooterToolbarPage implements OnInit {
#Input() public activeIndex:number;
constructor(private navCtrl: NavController) { }
ngOnInit() {}
public GoToPage() { console.log(this.activeIndex); }
}
HTML
<ion-toolbar color="dark">
<ion-buttons class="sidemargin" slot="secondary">
<ion-button (click)="GoToPage()"></ion-button>
</ion-buttons>
</ion-toolbar>
HTML of the component that use the component
<app-footertoolbar [activeIndex]="0" >
</app-footertoolbar>

Reposting my comment as requested:
I think if you have the [] around it then to pass a string back you would need "'dashboard'" (so a " with a ' inside it).
