Question

我认为这是许多编码人员目前面临的问题。

所以让我们找到一个解决方案：

我已经尝试过-> mailer2：^ 1.2.5

var options = GmailSmtpOptions()
..username = ''
..password = ''; 

var emailTransport = SmtpTransport(options);

var envelope = Envelope()
 ..from = ''
 ..recipients.add(email)
 ..subject = ''
 ..html = "<h1>Title </h1>\n\n"
    

 emailTransport.send(envelope)
    .then((envelope) => print('Email sent!'))
    .catchError((e) => print('Error occurred: $e'));

但出现以下错误消息：

有人知道如何在颤动的Web应用程序中发送电子邮件吗？（无需打开电子邮件标签）

Answer 1

“ mailer2”（和原始软件包“ mailer”）将导入dart:io，而在Flutter网站上则不可用，因此您不能使用此软件包。

我过去使用的一种发送电子邮件的解决方案是创建一个HTTP触发的云函数（例如Firebase函数，AWS Lambda，netlify函数）来发送电子邮件。您可以通过http请求传递所需的任何数据，并让云功能通过Node.js中的nodemailer之类的方式发送电子邮件。

也许还有其他服务或API已经可以执行云功能了，尽管我没有看到很多，但它们也不是我的首选方法
