[Android] Example app - card turns halfway then flips back

[f6m6]

Hi there :)

The card turns halfway, switches sides (correctly) but then instead of continuing to flip left to right, it flips back right to left.

So you end up in the correct state but the animation isn't a full flip.

It's like going halfway to turning the card over and then it magically changing what's on its front face, and then turning back - it breaks the illusion of a "card" existing and isn't the desired behaviour I think.

React Native 0.57

It works fine on iOS though

I modified the code：

if (Platform.OS === 'ios') {
        // cardB Y-rotation
        bYRotation = rotation.y.interpolate({
          inputRange: [0, 50, 100, 150],
          outputRange: ['0deg', '180deg', '0deg', '-180deg'],
          extrapolate: 'clamp'
        })
      } else {
        // cardB Y-rotation
        bYRotation = rotation.y.interpolate({
          inputRange: [0, 50, 100, 150],
          outputRange: ['0deg', '-180deg', '0deg', '180deg'],
          extrapolate: 'clamp'
        })
      }

The above code fixed the issue for me.

This is still an issue, certainly on android I don't know about ios.

rotation on 'x' axis works perfectly buy 'y' rotation is getting half way and then flipping back. I have the latest version but it still happens.

Update: I meant to say this works for 'y' and not for 'x', my mistake.
