Flutter：将经过身份验证的用户添加到 Firestore

Question

我正在尝试从注册页面对新注册的用户进行身份验证，并在他们通过身份验证后将其添加到我的 cloud-firestore 数据库中。目前，用户已通过身份验证，并且代码在该阶段运行良好。但是，它们不会添加到 cloud-firestore 数据库中。请帮忙！

Container(
                    width: 150.0,
                    child: FlatButton(
                      child: Text('Sign Up'),
                      color: Colors.grey,
                      onPressed: () {
                        if (_registerFormKey.currentState.validate()) {
                          if (pwdInputController.text ==
                              confirmPwdInputController.text) {
                            FirebaseAuth.instance
                                .createUserWithEmailAndPassword(
                                    email: emailInputController.text,
                                    password: pwdInputController.text)
                                .then((currentUser) => Firestore.instance
                                    .collection("users")
                                    .document(currentUser.user.uid)
                                    .setData({
                                      "uid": currentUser.user.uid,

                                      'password': pwdInputController.text,
                                    })
                                    .then((result) => {

您的代码在我的模拟器上运行良好，因此我会仔细检查以下内容，确保您已正确设置了 Firestore Documentation can be found here. 还要仔细检查您的数据库安全规则Documentation for security rules can be found here.

如果您的数据库仍处于测试阶段，您的规则将如下所示：

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {

    // This rule allows anyone on the internet to view, edit, and delete
    // all data in your Firestore database. It is useful for getting
    // started, but it is configured to expire after 30 days because it
    // leaves your app open to attackers. At that time, all client
    // requests to your Firestore database will be denied.
    //
    // Make sure to write security rules for your app before that time, or else
    // your app will lose access to your Firestore database
    match /{document=**} {
      allow read, write: if request.time < timestamp.date(2020, 5, 5);
    }
  }
}
