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 this issue too. I had a four screen bottom tabbed application and a 'logout' method. However, that logout method was calling a pushReplacementNamed. This prevented the class that held the global keys (different from the logout function) from calling dispose.

The resolution was to change pushReplacementNamed with popAndPushNamed to get back to my 'login' screen.
