Thanks for bringing this to our attention! The new Rive Flutter code does not yet handle audio events through FFI, which resulted in the underlying native resources being ref-counted but not passed to Flutter and ultimately never freed when the object gets garbage collected. We'll get this fixed soon.

This is fixed in 0.14.0-dev.5, please reopen if you're still running into issues. But be sure to also call dispose on any Rive resources you create so that they are deleted immediately on page exit.
