无法在 flutter firebase 中注册用户：firebase_auth/channel-error

Question

我正在尝试使用 firebase 注册用户，但我收到了 firebase 通道错误 以下是代码

import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:todo_fb_provider/models/usermodel.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

class SignUpSerivce {
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final FirebaseFirestore fireStore = FirebaseFirestore.instance;
  Future<void> createUser(BuildContext context, String userId, String userName,
      String name, String password, String gender, String email) async {
    try {
      UserCredential userCredential = await _auth
          .createUserWithEmailAndPassword(email: email, password: password);
      String uid = userCredential.user!.uid;
      Usermodel usermodel = Usermodel(
          email: email,
          userName: userName,
          userId: userId,
          gender: gender,
          password: password,
          name: name);

      await fireStore.collection('users').doc(uid).set(usermodel.toMap());
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(content: Text('User Created Successfully')),
      );
      print('User Created');
    } on FirebaseException catch (e) {
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(content: Text('Failed with error $e')),
      );
      print(e);
    } catch (e) {
      print(e);
    }
  }
}

我希望它使用提供的详细信息创建一个用户，但我得到以下内容

I/flutter (12898): [firebase_auth/channel-error] "dev.flutter.pigeon.firebase_auth_platform_interface.FirebaseAuthHostApi.createUserWithEmailAndPassword".

所有 Firebase 权限均设置为 true

确保创建用户时没有传递空参数。如果发送了正确的参数但仍然存在问题，则该电子邮件可能存在现有数据，如果是这样，请在更新记录时添加 setOptions。

await fireStore.collection('users').doc(uid).set({usermodel.toMap()}, SetOptions(merge: true));
