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

In my case I wanted to use the static GlobalKey _scaffoldKey but when I used the same widget multiple times it gave this duplicate error.

I wanted to give it a unique string and still use this scaffold state. So I ended up using:

static GlobalObjectKey _scaffoldKey

and in the initState:

_scaffoldKey = new GlobalObjectKey(id);

Edit: Actually, silly me. I just simply removed the static and made it GlobalKey again :)
