How to use ErrorHandler and IonicErrorHandler in ionic 2

Ionic Framework ionic-v3
2

New class:

import { ErrorHandler } from ‘@angular/core’;
import {IonicErrorHandler} from ‘ionic-angular’;

export class MyErrorHandler extends IonicErrorHandler implements ErrorHandler {

constructor() {
super();
}

handleError(err: any): void {
console.log('Error: ’ + err);
super.handleError(err);
}

}

In app.module.ts instead of:

[{ provide: ErrorHandler, useClass: IonicErrorHandler }]

use:

[{ provide: ErrorHandler, useClass: MyErrorHandler }]
