i had to tap on the favourite button to call the function but i want it whenever someone slides to right

Answer 1

There is an event for slide change: in HTML:

<ion-slides (ionSlideDidChange)="slideChanged()">

in TS:

slideChanged() {
    let currentIndex = this.slides.getActiveIndex();
    console.log('Current index is', currentIndex);
  }

Answer 2

<ion-slides ionSlideWillChange="whenChangeSlide()"></ion-slides>

whenChangeSlide(){
  console.log('Do something')
}

Did you see the docs for slides , maybe can help you?
