你正在尝试转换一个Map<Object？，Object？> object到List<Object？“对象，这是不可能的。
修改decode方法来处理Map<Object？，Object？> type.如根据下面提供的代码实现的。如果你遇到什么问题请告诉我。

static PigeonInitializeResponse decode(Object result) {
  final List<Object?> resultList = result as List<Object?>;
  return PigeonInitializeResponse(
    name: resultList[0]! as String,
    options: PigeonFirebaseOptions.decode(resultList[1]!),
    isAutomaticDataCollectionEnabled: resultList[2] as bool?,
    pluginConstants: (resultList[3] as Map<Object?, Object?>?)?.cast<String?, Object?>(),
  );
}
