     * @name Input
     * @description
     *
     * `ion-input` is meant for text type inputs only, such as `text`,
     * `password`, `email`, `number`, `search`, `tel`, and `url`. Ionic
     * still uses an actual `<input type="text">` HTML element within the
     * component, however, with Ionic wrapping the native HTML input
     * element it's better able to handle the user experience and
     * interactivity.
     *
     * Similarly, `<ion-textarea>` should be used in place of `<textarea>`.
     *
     * An `ion-input` is **not** used for non-text type inputs, such as a
     * `checkbox`, `radio`, `toggle`, `range`, `select`, etc.
     *
     * Along with the blur/focus events, `input` support all standard text input
     * events like `keyup`, `keydown`, `keypress`, `input`, etc. Any standard event
     * can be attached and will function as expected. Example: `<ion-input (click)="someFunction()"></ion-input>`
     *
     * @usage
     * ```html
     * <ion-list>
     *   <ion-item>
     *     <ion-label color="primary">Inline Label</ion-label>
     *     <ion-input placeholder="Text Input"></ion-input>
     *   </ion-item>
     *
     *   <ion-item>
     *     <ion-label color="primary" fixed>Fixed Label</ion-label>
     *     <ion-input type="tel" placeholder="Tel Input"></ion-input>
     *   </ion-item>
     *
     *   <ion-item>

     *
     * `ion-textarea` is used for multi-line text inputs. Ionic still
     * uses an actual `<textarea>` HTML element within the component;
     * however, with Ionic wrapping the native HTML text area element, Ionic
     * is able to better handle the user experience and interactivity.
     *
     * Note that `<ion-textarea>` must load its value from the `value` or
     * `[(ngModel)]` attribute. Unlike the native `<textarea>` element,
     * `<ion-textarea>` does not support loading its value from the
     * textarea's inner content.
     *
     * When requiring only a single-line text input, we recommend using
     * `<ion-input>` instead.
     *
     * @usage
     * ```html
     *  <ion-item>
     *    <ion-label>Comments</ion-label>
