Duplicate GlobalKey detected in widget tree

Question

I am running into a globalKey error after I navigate from Screen A to Screen B and click a \"Cancel\" button to go back to Scree

Answer 1

I had a similar problem. in my case the problem was that I had a function in dispose method of screen B and it wouldn't execute properly. I just removed it and the problem was fixed.

so be sure your dispose method is executed properly in all screens.
