数据未存储在 Firestore 中，但用户的身份验证信息在 Firebase 身份验证中可用

Question

我尝试在通过“createUserWithEmailAndPassword”创建用户时在 Firestore 中添加用户的数据。提交按钮后，它不会定向到下一页，而是将用户添加到 Firebase 身份验证中，但未添加到 Firestore 集合中。

下面是添加用户的代码：

`auth.createUserWithEmailAndPassword(_email, _password, _name).then((value){
FirebaseFirestore.instance.collection('users').doc().set({
"email" : _email,
"userName" : _name,}).then((res)
{Navigator.of(context).pushReplacementNamed('/home');});});`

错误：

请检查这个类似的 SO 问题：

Firebase Authentication creates user but does not add their Info to database

他们建议在您的代码中添加print 语句以检查错误消息。

您还应该检查安全规则，因为这可能会解决您的问题。
