/**
 * @name ToastController
 * @description
 * 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.
 *
 * ### Creating
 * All of the toast options should be passed in the first argument of
 * the create method: `create(opts)`. The message to display should be
 * passed in the `message` property. The `showCloseButton` option can be set to
 * true in order to display a close button on the toast. See the [create](#create)
 * method below for all available options.
 *
 * ### Positioning
 * Toasts can be positioned at the top, bottom or middle of the
 * view port. The position can be passed to the `Toast.create(opts)` method.
 * The position option is a string, and the values accepted are `top`, `bottom` and `middle`.
 * If the position is not specified, the toast will be displayed at the bottom of the view port.
 *
 * ### Dismissing
 * The toast can be dismissed automatically after a specific amount of time
 * by passing the number of milliseconds to display it in the `duration` of
 * the toast options. If `showCloseButton` is set to true, then the close button
 * will dismiss the toast. To dismiss the toast after creation, call the `dismiss()`
 * method on the Toast instance. The `onDidDismiss` function can be called to perform an action after the toast
 * is dismissed.
 *
 * @usage
 * ```ts
 * import { ToastController } from 'ionic-angular';
 *
 * constructor(public toastCtrl: ToastController) { }
 *
 * presentToast() {
 *   const toast = this.toastCtrl.create({
 *     message: 'User was added successfully',
 *     duration: 3000,
 *     position: 'top'
 *   });
 *
 *   toast.onDidDismiss(() => {
 *     console.log('Dismissed toast');
 *   });
 *
 *   toast.present();
 * }
 * ```
