A Toast is a subtle notification commonly used in modern applications. It can be used to provide feedback about an operation or to display a system message. The toast appears on top of the app’s content and can be dismissed by the app to resume user interaction with the app. Example

presentToast() {
  let toast = this.toastCtrl.create({
    message: 'User was added successfully',
    duration: 3000,
    position: 'top'

  toast.onDidDismiss(() => {
    console.log('Dismissed toast');
