我想知道是否有人可以告诉我如何实现 Flutter StreamProvider“catchError”属性？

下面的示例代码添加到：

StreamProvider<LocationModelNormal>.value(
    initialData: LocationModelNormal.initialData(),
    stream: locationStreamInstance.specificLocation(_secondWonder),
    catchError: ?????????
),

class LocationModelNormal {
  final String name;
  LocationModelNormal({
    this.name
  });
  factory LocationModelNormal.fromMap(Map<String, dynamic> data) {
    return LocationModelNormal(
      name: data['name'] ?? '',

    );
  }
  factory LocationModelNormal.initialData() {
    return LocationModelNormal(
      name: '',
    );
  }
}
