`======== Exception caught by animation library =====================================================
The following assertion was thrown while notifying listeners for AnimationController:
'package:flutter/src/widgets/scroll_notification.dart': Failed assertion: line 186 pos 15: 'overscroll.isFinite': is not true.

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
https://github.com/flutter/flutter/issues/new?template=2_bug.md

When the exception was thrown, this was the stack:

#6 ScrollPositionWithSingleContext.setPixels (package:flutter/src/widgets/scroll_position_with_single_context.dart:82:18)
...
