The next set of directives and services are for gestures. If you did not already know, gestures are actions that a user performs on the screen when interacting with the application. An example of a gesture is pinching to zoom-out or pinching-in to zoom-in (just like on a smartphone).

Ionic supports these gestures and lets you handle them using the $ionicGesture service inside your controller or directive.

To make things more generic, I will explain one gesture directive and show how you can work with it. The same logic applies to all the other gestures.

We will be testing the on-drag-up directive by scaffolding a new blank app; run this:

ionic start -a "Example 26" -i app.example.twentysix example26 blank

Using the cd command, go to the example26 folder and run this:

  ionic serve

This will launch the blank template in the browser.

First, we will create a controller named AppCtrl in www/js/app.js.

.controller('AppCtrl', function($scope, $ionicGesture) {

    $scope...
