FlutterFire - 在哪里通过 FirebaseAuth 上的电子邮件获取验证码 #

Question

我刚开始使用 FIrebase
随着重大更新，FlutterFire 添加了新方法

NEW: Added support for applyActionCode().  
NEW: Added support for checkActionCode().  
NEW: Added support for verifyPasswordResetCode().

和文档https://firebase.flutter.dev/docs/auth/usage/

User user = FirebaseAuth.instance.currentUser;
if (!user.emailVerified) {
   await user.sendEmailVerification();
}

//Firebase will send an automated email to the user with a unique code. 
//This code can then be entered via the applyActionCode() method. 
//You can first check whether the code is valid by using the checkActionCode() method:  

等待 user.sendEmailVerification(); 这只会向用户电子邮件发送验证链接以进行验证。不是验证码。

我应该怎么做才能通过电子邮件接收该代码？所以我可以使用verifyPasswordResetCode()方法。. 谢谢
