For some reason it's throwing me this error for line 19 (highlighted)

The named parameter 'child' isn't defined.

Is there anything I'm not seeing?

Thanks!

The AppBar widget does not have any child property. You need to change it with the action.

here is example

appBar: AppBar(
    actions: <Widget>[
        RaisedButton(
          onPressed: () async {},
          child: Text('Sign in Anen'),
       ),
    ],
),
