This package seems to be abandoned. I've forked it and fixed the latest flutter compatibility issues along with some other stuff.
You can use it by adding:
To pubspec.yaml

better_player:
    git: https://github.com/Lo4D/better-player-ultra.git

This solution worked for me.
Instead of forking you can make a PR to better player? Sorry if I am missing something.
