Utilize the back button to navigate to the previous slide in Ion-Slide-Box

I'm facing a challenge in my Ionic app where I have an ion-slide-box containing 3 slides. The swiping feature is disabled, and I navigate to the next slide using a button that triggers

$ionicSlideBoxDelegate.slide(index)

Now, I am looking for a way to go back one slide when the user presses the back button on their mobile phone. Ideally, this would be achieved using $ionicHistory.goBack()

In addition, I want the app to remember the last viewed slide when navigating away from the slide-box and returning to it at a later time.

If anyone has any insights or solutions on how to accomplish this, I would greatly appreciate the help!

Big thank you to beaver and the_mahasagar for their help!

The solution involves using the

$ionicPlatform.registerBackButtonAction(function (event) {})

function.

I also utilized ng-init=init_function() in order to check the state, especially when coming from $ionicHistory.goBack() to navigate directly to the correct slide.

For those who are curious, below is the fundamental code snippet:

$scope.currentSlide = 0

$scope.nextSlide = function() {
    $scope.currentSlide++
    $scope.goToSlide($scope.currentSlide)
}

$scope.goToSlide = function(index) {
    $ionicSlideBoxDelegate.slide(index)
}

$ionicPlatform.registerBackButtonAction(function (event) {
    if($scope.currentSlide > 0)
        $scope.goToSlide($scope.currentSlide-1)
    else
        $ionicHistory.goBack()
}, 140)

$scope.init_function = function() {
    if(STATE) // a specific state after navigating to a new view and returning via $ionicHistory.goBack()
        $scope.goToSlide(NUMBER)
}

It's important to implement checks such as determining if it is the last slide, etc.
