React-native-deck-swiper: swiper.swipeBack() method broken in 1.2.0

[alexbrillant]

Adding swipe labels broke swipe back feature

[vishalTechnoFreek]

is it fixed?

[alexbrillant]

@vishalTechnoFreek no

[webraptor]

Does this occur because swipeDirectionCallback is not a function ?

[angryanatole]

any updates on this issue?

[webraptor]

It is working fine for me. Perhaps you should give more details into what your error is.

[angryanatole]

in my case it goes to previous card without animation. it also takes about two seconds to see the previous card.

for now, I ended up using jumpToCardIndex() to go to the previous card.

[webraptor]

There's no swipeBack animation. If you check the readme, it is in the todo list: Swipe back to the previous card with a custom animation

@alexbrillant @webraptor any update on swipe back animation. Would love to have it because excluding the back animation this library is perfect.

@alexbrillant Was it closed because it's fixed ? 🤔

[webraptor]

@xavier-villelegier yes, fixed a while ago... Still no animation though... But calling swipeBack puts the last swiped card back on top of the deck.

[xavier-villelegier]

@webraptor Mmh swipeBack still doesn't work for me though, here is a snack repro.

Did I miss something ?

[webraptor]

I think you're missing the swipeBack callback function ... https://snack.expo.io/H1t_QvBJQ

Just opened the swiper code and looks like there's no verification if a callback method exists or not, it just calls the method

onSwipedCallbacks = (swipeDirectionCallback, swipedAllCards) => {
    const previousCardIndex = this.state.firstCardIndex
    this.props.onSwiped(previousCardIndex)

    error here ---- >>> swipeDirectionCallback(previousCardIndex)
    if (swipedAllCards) {
      this.props.onSwipedAll()
    }
  }

You can either put an empty callback like in the snack above, or wait for the issue to be fixed in a later PR.

PS: @xavier-villelegier it be great if you could create a new issue with your repro above. thanks.

[xavier-villelegier]

@webraptor That worked, my bad I just misunderstood the docs on this function. Thanks a lot 👍
