【问题描述】：
我正在构建一个颤振应用程序，它有一个联系表格。填写联系表格后，当用户在没有第三方的情况下按下提交时，我希望用户提供的数据从联系表格发送到我的电子邮件地址（或我将提供的电子邮件地址）。我的表单有预定义的字段，这些字段将由用户填写。提交后，我希望将表单发送到管理员的电子邮件地址。 我不是在谈论在我的应用中发送邮件
我已经完成了此处提出的附加问题，看起来很相似，但它没有回答我的问题。我曾尝试使用 url_launcher 包，但这也无济于事。
Flutter, Sending Form Data to Email

【问题讨论】：
-
您需要澄清“我希望将数据发送到我的电子邮件地址”是什么意思，您是否想要： a) 通过意图打开默认邮件应用程序； b) 通过 SMTP 直接从您的应用程序发送电子邮件； c) 别的东西（请详细说明）。哦，顺便说一句：a) 和 b) 包含在您发布的链接问题中，您只需向下滚动一点。

我想要的是在用户填写表格后，我希望将数据直接发送到我的电子邮件地址。 @Uroš
