Firebase 颤振：解决执行updateData时出错，未找到：没有要更新的文档,firebase,flutter,google-cloud-firestore,flutter-change-notifier,Firebase,Flutter,Google Cloud Firestore,Flutter Change Notifier,当我尝试更新firebase数据库中的用户数据时，出现以下错误 E/flutter ( 4756): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(Error performing updateData, NOT_FOUND: No document to update: projects/(DBname)/databases/(default)/documents/user

当我尝试更新firebase数据库中的用户数据时，出现以下错误

E/flutter ( 4756): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(Error performing updateData, NOT_FOUND: No document to update: projects/(DBname)/databases/(default)/documents/userData/ckua6TCjc2Dx76W6efuV, null)

这是我的UserData模型类

class UserData {
//  String userId;
  String id;
  String firstName;
  String lastName;
  String phoneNumber;
  String role;
  String streetAddress;
  String city;
  String state;
  String postcode;
  String country;
  Timestamp createdAt;
  Timestamp updatedAt;

  UserData();

  UserData.fromMap(Map<String, dynamic> data) {
    id = data['id'];
//    userId = data['user_id'];
    firstName = data['first_name'];
    lastName = data['last_name'];
    phoneNumber = data['phone_number'];
    role = data['role'];
    streetAddress = data['street_address'];
    city = data['city'];
    postcode = data['postcode'];
    state = data['state'];
    country = data['country'];
    createdAt = data['created_at'];
    updatedAt = data['updated_at'];
  }

  Map<String, dynamic> toMap() {
    return {
      'id': id,
//      'user_id': userId,
      'first_name': firstName,
      'last_name': lastName,
      'phone_number': phoneNumber,
      'role': role,
      'street_address': streetAddress,
      'city': city,
      'postcode': postcode,
      'state': state,
      'country': country,
      'created_at': createdAt,
      'updated_at': updatedAt,
    };
  }
}
