Resolving Duplicate GlobalKey Errors in Flutter Widget Tree

In this video i tried to show how to solve when compiler gives "Duplicate GlobalKey detected in widget tree." or "Multiple widgets used the same GlobalKey". That means you are using the form widget and inside the form widget you are using same global key so that you are getting this error.In my case i used different global keys inside the form widget even that i was also getting this problem. because here to navigated the screen i used
"navigator.push" which does not destroy the previous screen so that when it was navigating to the next screen it was also taking the previous widget and formkey. To Solve this error we can simply use "navigator.pushReplasement" instead of "Navigator.push". After doing it i hope your problem should be solved.
