ionic 3 EmailValidator usage

I'm using newest ionic framework and I see that angular dev team added EmailValidator feature. But it's a little bit unclear how I should use it. Can anybody give me an example of usage?

home.html

<ion-content padding>

    <ion-list>

        <ion-item margin-vertical>
            <ion-label>Enter email</ion-label>
            <ion-input type="email" name="email" [(ngModel)]="email"></ion-input>
        </ion-item>

    </ion-list>

    <button (type)="button" ion-button block large [disabled]="!email" (click)="checkValidation()">Check!</button>

</ion-content>

home.ts

import { Component } from '@angular/core';
import { IonicPage } from 'ionic-angular';
import { EmailValidator } from '@angular/forms';

@IonicPage()
@Component({
     selector: 'page-login',
     templateUrl: 'home.html'
})

export class LoginPage  {
    email: string;

    constructor() {}

    checkValidation() : string () {
        // validation here
    }

}
