In ionic4 there currently isn't an attribute for scroll starting position. However, there is a scroll method you can use on page initialisation which you can use like so:
.ts
import { Component, ViewChild } from '@angular/core';
import {IonContent} from '@ionic/angular';
@Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {
@ViewChild(IonContent) theContent: IonContent;
ngOnInit() {this.theContent.scrollToPoint(0,150).then(()=>{}) }
}
}
comment if you need anything clarifying
