### Steps to reproduce

1. Run the code sample
2. Execute a hot reload

### Expected results

I expected the hot reload to succeed.

### Actual results

An exception occurred:
```
The following assertion was thrown while finalizing the widget tree:
Multiple widgets used the same GlobalKey.
The key [GlobalObjectKey int#c5097] was used by multiple widgets. The parents of those widgets were different widgets that both had the following description:
  Builder
A GlobalKey can only be specified on one widget at a time in the widget tree.
```
