error in debug console on anonymous logout about time_tracker_flutter_course

Adding listen:false to the Provider in the _signOut method resolves the issue. See PR #3

class AccountPage extends StatelessWidget {
  Future<void> _signOut(BuildContext context) async {
    try {
      final auth = Provider.of<AuthBase>(context, listen: false);
      await auth.signOut();
    } catch (e) {
      print(e.toString());
    }
  }
