我无法在firebase上创建新的集合用户。我正在ScopedModel中进行状态管理，并且我知道数据库与应用程序连接良好，所以我不知道到底出了什么问题，我只是知道每次注册都会失败。如果有必要，我可以共享github存储库，以便大家仔细查看该项目。我真的很需要帮助，因此对有意见的人都开放。
userModel
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/cupertino.dart';
import 'package:scoped_model/scoped_model.dart';
class UserModel extends Model {
FirebaseAuth _auth = FirebaseAuth.instance;
FirebaseUser firebaseUser;
Map<String, dynamic> userData = Map();
bool isLoading = false;
void signIn() async {
isLoading = true;
notifyListeners();
await Future.delayed(Duration(seconds: 3));
isLoading = false;
notifyListeners();
}
void signUp (
{@required Map<String, dynamic> userData,
@required String pass,
@required VoidCallback onSuccess,
@required VoidCallback onFail}) {
isLoading = true;
notifyListeners();
_auth
.createUserWithEmailAndPassword(
email: userData["email"], password: pass)
.then((user) async {
firebaseUser = user.user;
print(firebaseUser.uid);
await _saveUserData(userData);
onSuccess();
isLoading = false;
notifyListeners();
}).catchError((e) {
onFail();
isLoading = false;
notifyListeners();
});
}
void recoverPass() {}
Future<Null> _saveUserData(Map<String, dynamic> userData) async {
this.userData = userData;
await Firestore.instance
.collection("users")
.document(firebaseUser.uid)
.setData(userData);
}
}
