node.js - 为什么Mongo数据库中的数据和我从flutter App输入的数据不一样？

Question

我正在尝试从颤振 UI 获取数据并使用 Bloc 状态管理将其发送到节点服务器。作为响应，它应该向电子邮件发送验证码或重新发送电子邮件代码的消息...我一直拥有重新发送电子邮件和一条错误消息，说电子邮件和密码不被接受！！并将数据库中的用户数据保存为实例！但是当我重新输入相同的电子邮件以注册为新用户时，Node 会给出一个 200 状态代码，并带有一条消息，表明用户已经存在！ PS：我已经从电子邮件 The Bloc Class中打开了安全性较低的应用程序和 Recaptcha ：

                          ),

事件文件：

abstract class AuthEvent {}

class RegisterEvent extends AuthEvent {}

class EmailEvent extends AuthEvent {
  String email;
  EmailEvent(email) {
    this.email = email;
  }
}

class PasswordEvent extends AuthEvent {
  String password;
  PasswordEvent(password) {
    this.password = password;
  }
}

class UsernameEvent extends AuthEvent {
  String username;
  UsernameEvent(username) {
    this.username = username;
  }
}

保存在数据库中的是：名称：'_StreamSinkWrapper 的实例密码已加密 电子邮件：'_StreamSinkWrapper 的实例

请问有什么解决办法吗？？谢谢。
