Exception when use controller to close

[j574144]

Hi. when use it inside tab view, after change of tab, I have this exception:

Basically in this case we need use animation after dispose, any idea?

AnimationController.reverse() called after AnimationController.dispose()
AnimationController methods should not be used after calling dispose.
'package:flutter/src/animation/animation_controller.dart':
Failed assertion: line 488 pos 7: '_ticker != null'

Please ignore it, This was a mistake from me.
