为什么“email_sender”在此 Web 应用程序项目中未激活？
问题描述 投票：0回答：1
包：email_sender firebase 使用：是
我想在我的项目中使用发件人电子邮件，因此包“flutter_email_sender”不起作用，因为它不适用于网络应用程序，然后我尝试另一个包“email_sender”，它用于网络应用程序项目，我尝试了但它得到了像这样的“somethingWrong”错误

那么为什么 email_sender 不起作用，有人尝试这个 email_sender 吗？或者谁有其他方法在 flutter web 应用程序中发送电子邮件？

如果没有配置 SMTP 服务器或没有某种类型的帐户（例如 Firebase），您将找不到发送电子邮件的包。
如果您的应用程序可以像那样发送电子邮件，那将是垃圾邮件发送者的梦想。
我不确定是否可以通过浏览器连接到电子邮件服务器。通常，您连接到后端，后端会发送一封邮件，因为它能够更好地处理任何后果，并且假设您不希望用户在您的应用程序中输入自己的凭据，那么那里的凭据也更安全.
