[Android] Cannot read property 'addListener' of undefined

[ermamud]

Hi,
I am React Native with Expo (v0.72.5) and after installing this package using the expo command, I am getting an error only on Android.
I created the same IntroModal you have in the examples and this is the error:

TypeError: Cannot read property 'addListener' of undefined

hi @ermamud! could you add a repro on snack please? this would help a lot, thx!

[ermamud]

I am not able to reproduce the same exact issue using a snack, after further testing, I am getting the previous error on both iOS and Android but only after I did a native build, previously it was just working fine.

I created this snack and you can see that is not working, not sure if it's the same error because I don't see any error, the web version works fine but the ios/android is freezing after trying to open the modal:

thanks

hey @ermamud, sorry for the long delay. i hope you managed to sort this out, but just in case, here's your snack fixed. you can focus on ./components/introModal.tsx: https://snack.expo.dev/trVMWWgcMpHkd6jpBYZKW.

tldr;: the way you were updating animatedValue + the use of View instead of Animated.View is what was causing the "crash".
