Click listener throws an assert error #451
Description
Description
Creating a click listener in Rive and using it in Flutter results in the error below, although the animation works fine.
======== Exception caught by gesture library =======================================================
The following assertion was thrown while dispatching a pointer event:
'package:flutter/src/gestures/multidrag.dart': Failed assertion: line 254 pos 12: '!_pointers!.containsKey(event.pointer)': 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:
