Spam dropdown create an error

[Tweentyy]

Hello, If we spam the open/close dropdown with the example in the doc, an error is produced :

'package:flutter/src/widgets/overlay.dart': Failed assertion: line 1823 pos 12: 'SchedulerBinding.instance.schedulerPhase != SchedulerPhase.persistentCallbacks': 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.yml

The AnimationController notifying status listeners was: AnimationController#01ac7(⏮ 0.000; paused)
