如何在flutter中发送一封验证电子邮件（）

Question

当用户单击“注册”按钮时，我不会发送电子邮件验证。到目前为止，我的注册代码发送了电子邮件验证，但用户无法导航到下一页（CignularProgressIndicator继续加载），

这是我的代码

   onPressed: () async {
                  if (_regFormKey.currentState!.validate()) {
                     setState(() {
                    _isProcessing = true;
                  });

                    User? user = await FireAuth.registerUsingEmailPassword(
                      name: nameController,
                      email: _emailController.text,
                      password: _passwordController.text,
                    );        
                    if (user != null) {
                      bool EmailSent = user.sendEmailVerification() as bool;

                   //I think something is wrong here
                    if (EmailSent) {
                       Navigator.of(context).pushAndRemoveUntil(
                        MaterialPageRoute(
                          builder: (context) => ProfilePage(user: user),
                        ),
                        ModalRoute.withName('/'),
                      );  }

                    }  else{
                        ScaffoldMessenger.of(context)
                        .showSnackBar(SnackBar(content: Text(' Account exists or Network problems'),
                         backgroundColor: Colors.red,
                        ));}

                     setState(() {
                      _isProcessing = false;
                    });
                  
                }}

sendemailverification（）返回future＆lt; void＆gt; so emailsent不会设置。您应该等待 中的验证调用尝试...捕获以处理响应。

更像这样：

if (user != null) {
  try {
    await user.sendEmailVerification();
    /// sent successfully
    // TODO: put your navigation here
  } catch (e) {
    /// error sending verification
    // TODO: show snackbar
    // TODO: set _isProcessing to false
  }
}
