dispose method Null safety

  1. @mustCallSuper
void dispose()
mustCallSuper">@mustCallSuper

Releases any resources used by the object.

This method is called by the owner of this gesture recognizer when the object is no longer needed (e.g. when a gesture recognizer is being unregistered from a GestureDetector, the GestureDetector widget calls this method).

Implementation

@mustCallSuper
void dispose() { }
