════════ Exception caught by animation library ═════════════════════════════════
The following assertion was thrown while notifying listeners for AnimationController:
EasyRefreshPhysics.applyBoundaryConditions returned invalid overscroll value.

The method was called to consider a change from 77.05522621990576 to 65.90870477447844, which is a delta of -11.1 units. However, it returned an overscroll of 65.9 units, which has a greater magnitude than the delta. The applyBoundaryConditions method is only supposed to reduce the possible range of movement, not increase it.
The scroll extents are 0.0 .. 0.0, and the viewport dimension is 836.0.
When the exception was thrown, this was the stack
