I/flutter ( 7268): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
I/flutter ( 7268): The following assertion was thrown while finalizing the widget tree:
I/flutter ( 7268): _AnimatedListViewItemState#bec5f(ticker active) was disposed with an active Ticker.
I/flutter ( 7268): _AnimatedListViewItemState created a Ticker via its SingleTickerProviderStateMixin, but at the time
I/flutter ( 7268): dispose() was called on the mixin, that Ticker was still active. The Ticker must be disposed before
I/flutter ( 7268): calling super.dispose(). Tickers used by AnimationControllers should be disposed by calling
I/flutter ( 7268): dispose() on the AnimationController itself. Otherwise, the ticker will leak.
I/flutter ( 7268): The offending ticker was: Ticker(created by _AnimatedListViewItemState#bec5f(lifecycle state:
I/flutter ( 7268): created))
I/flutter ( 7268): The stack trace when the Ticker was actually created was:
