_nextKey is null

[rizaldi-wiratama]

Hello @EdsonBueno first of all thankyou for this great package

i recently have an issue reported on our sentry about this package like this

then i search about this & found that this code is the issue , that _nextKey is null

i think this issue is rare case and we just got 4 event in same user

oh yeah i use PagedListView like this

is there a case that the problem may exist? because now i can't reproduce this issue
or maybe do you have any suggestion / solution based on this issue? thankyou

If anyone have same issue/solution for this issue please feel free to comment thankyouu :)

Its possible the PageController is somehow disposed between this check and the next frame.
We could add a safety check.
