That widget have been changed to OutlinedButton.

Old Widget was : OutlineButton
Old Theme was : ButtonTheme
New Widget is : OutlinedButton
New Theme is : OutlinedButtonTheme

Here's an example :

OutlinedButton(
    style: OutlinedButton.styleFrom(
        shape: StadiumBorder(),
            side: BorderSide(
              width: 2,
              color: Theme.of(context).colorScheme.primary,
            ),
        ),
    onPressed: () { dismissDialog(); },
    child: Text('New Outlined Button'),
),

CodePudding user response：

Yes. That is a breaking change. And it is listed up top in the breaking changes documentation:

The FlatButton, RaisedButton and OutlineButton widgets have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively.
