随着 Getx 的大肆宣传，我选择在我的第一个项目中使用它，不幸的是，与其他人相比，关于 getx 的教程并不多。这是我的第一个构建，如何创建一个用户 ID 作为文档 ID，我遵循 MVC 模式，这是该构建的控制器。

这是我的代码。

import 'package:firebase_auth/firebase_auth.dart';
import 'package:get/get.dart';

import 'package:wlykmain/views/homepage.dart';
import 'package:wlykmain/views/login.dart';

class FirebaseController extends GetxController {
  bool isHidden = true;

  void toggleBetween() {
    isHidden = !isHidden;
    update();
  }

  FirebaseAuth _auth = FirebaseAuth.instance;

  Rx<User> _firebaseUser = Rx<User>();

  String get user => _firebaseUser.value?.email;

  @override
  // ignore: must_call_super
  void onInit() {
    _firebaseUser.bindStream(_auth.authStateChanges());
  }

  void signUp(
    String firstname,
    String lastname,
    String email,
    String password,
  ) async {
    CollectionReference reference =
        FirebaseFirestore.instance.collection("Users");
    String uid = _auth.currentUser.uid;
    reference.doc(uid).set({});
    Map<String, dynamic> userdata = {
      "First Name": firstname,
      "Last Name": lastname,
      "Email": email,
      "uid": uid
    };

    await _auth
        .createUserWithEmailAndPassword(email: email, password: password)
        .then((value) {
      reference.add(userdata).then((value) => (Get.offAll(LoginPage())));
    }).catchError(
      (onError) => Get.snackbar(
        'Error creating account',
        onError.message,
        snackPosition: SnackPosition.TOP,
      ),
    );
  }

  void login(String email, String password) async {
    CollectionReference reference =
        FirebaseFirestore.instance.collection("Users");
    String uid = _auth.currentUser.uid;
    reference.doc(uid).set({"uid": uid});

    return await _auth
        .signInWithEmailAndPassword(email: email, password: password)
        // ignore: unnecessary_statements
        .then((value) {
      (Get.offAll(MyHome()));
    }).catchError(
      (onError) => Get.snackbar('Error while logging in', onError.message),
    );
  }

  void signOut() async {
    await _auth.signOut().then((value) => Get.offAll(LoginPage()));
  }
}

您应该在您的方法中替换add()为：doc(uid).set()signUp()

void signUp(
    String firstname,
    String lastname,
    String email,
    String password,
  ) async {
    // ... 

    await _auth
        .createUserWithEmailAndPassword(email: email, password: password)
        .then((value) {
      reference.doc(uid).set(userdata).then((value) => (Get.offAll(LoginPage())));
    }).catchError(
      (onError) => Get.snackbar(
        'Error creating account',
        onError.message,
        snackPosition: SnackPosition.TOP,
      ),
    );
  }

add()为该 Cloud Firestore 文档生成一个新密钥，同时doc()让您指定一个密钥。
