Answer 1

You can do this in three simple steps.

1. Make sure you have a key for scaffold. You can create that by writing the below code:

   final _scaffoldKey = GlobalKey();
   

2.Now you have to mention this key inside your Scaffold, by writing the below line inside scaffold:

key:_scaffoldKey,

3. Now you can show snackbar by writing:

   final snackBar=SnackBar(
                         content: Text('Your password has been changed successfully'),
                       );
                       _scaffoldKey.currentState.showSnackBar(snackBar);
