I didn't notice any breaking change in flame_audio, but I am getting some conflicts with multiple definitions of the Split class.

Aaah right, that is due to the devtools extension, I'll migrate that when I get home from Google I/O (the name changed in the new version).

Okay, I'll leave it up to you then. I tried hiding the other definition but now it fails analyze saying Split is not exported.

Okay, I'll move that change into a separate PR tomorrow
