Anyone encountered this exception error related to Audioplayers in the master channel?

I think #406 fixes this, could you please try again against master (not released)?

Updated with the commits in #406 but exception error remains. Looks like it is an issue with flutter itself.

I assume this has been fixed in the later versions, as it works fine for me on all platforms. Please open a new issue if the problem still occurs.
