4 years ago Just looked into this, I believe the issue was that the animation controller for the dough widget was being disposed after its parent ticker was disposed. I just published a new version 0.0.5, could you pull this down and see if this fixes the issue?

Hello. Am getting the above error when I pop the containing page. Am I doing something wrong?
Love the package otherwise, thanks!
════════ Exception caught by widgets library ═══════════════════════════════════ The following assertion was thrown while finalizing the widget tree: _DoughState#6945b(ticker active) was disposed with an active Ticker.
_DoughState created a Ticker via its SingleTickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. The Ticker must be disposed before calling super.dispose().
Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.
The offending ticker was: Ticker(created by _DoughState#6945b(lifecycle state: created)) The stack trace when the Ticker was actually created was:
0 new Ticker.
