======== Exception caught by widgets library =======================================================
The following assertion was thrown while finalizing the widget tree:
_EasyRefreshState#5085c(tickers: tracking 2 tickers) was disposed with an active Ticker.

_EasyRefreshState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. All Tickers 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: _WidgetTicker(created by _EasyRefreshState#5085c)
The stack trace when the _WidgetTicker was actually created was:

解决方法 easy_refresh.dart
@OverRide
void dispose() {
super.dispose();
_headerNotifier.dispose();
_footerNotifier.dispose();
_userOffsetNotifier.dispose();
}

替换成
@OverRide
void dispose() {
_headerNotifier.dispose();
_footerNotifier.dispose();
_userOffsetNotifier.dispose();
super.dispose();
}
