fix(ts): add null to getCurrentTrack return type

[qmx]

TrackPlayer returns null on iOS when current index is out of bounds/invalid

@qmx this is a good catch. I just did some investigation on the Android side and it looks like the issue might be slightly larger.

Looking at how Android handles this it looks like it might return a -1 in these cases where iOS returns null. Would you be able to test and confirm that?

If that's the case then we might need to update that Kotlin function to check the same conditions as iOS so that the API's are consistent.

Thanks for the contribution!

Testing android is harder for me - I don't even know how could I repro that tbh.

Would it make sense to actually get iOS to return the -1 too and deal with this at the react native level?

Definitely think parity would be good. We can start with having both platforms return -1 if there’s no current track.

@dcvz I ended up updating the Android API behavior to match iOS

fixed the linter/prettier formatting error

Thanks for this @qmx !
