Flutter - Display the SnackBar using the GlobalKey

In this video I cover displaying the snack bar using the global key.
In this episode I cover:
- Create an app with two tabs
- Construct a GlobalKey for the Page Scaffold
- Pass the GlobalKey to the tabs widgets
- On change in tab will show the Snackbar

Brandon, thanks for the video. I'm just starting with flutter and wondering why we couldn't just use `Scaffold.of(context).showSnackBar()` here ? Best

You can, however, you will need to use a Builder to wrap around the Scaffold and use the context given by the Builder => build: (context) to display the snackBar.
