The following assertion was thrown during a scheduler callback:
This widget has been unmounted, so the State no longer has a context (and should be considered defunct).

Consider canceling any active work during "dispose" or using the "mounted" getter to determine if the State is still active.
When the exception was thrown, this was the stack

Overwriting the original Transformer_Page_view package solves the problem
