Extracted Widget Lacks Access to error Variable, Causing Undefined Name Error

[stephane-archer]

      error: (error, stackTrace) => Center(
        child: Text(
          'Error: $error',
          style: const TextStyle(color: CupertinoColors.systemRed),
        ),
      ),

extract the widget on the Center widget

class A extends StatelessWidget {
  const A({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text(
        'Error: $error',
        style: const TextStyle(color: CupertinoColors.systemRed),
      ),
    );
  }
}

Undefined name 'error'. Try correcting the name to one that is defined, or defining the name.

expected code:

class FavoriteFoldersErrorWidget extends StatelessWidget {
  final Object error;
  const FavoriteFoldersErrorWidget({
    required this.error,
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text(
        'Error: $error',
        style: const TextStyle(color: CupertinoColors.systemRed),
      ),
    );
  }
}
