我不知道如何通过这个错误。我输入了一封与 MockUser 无关的电子邮件，然后它会转到 RegisterFormLogin 小部件。当我在字段中输入内容然后单击保存并登录的 ElevatedButton 时，我收到此错误：

包 https://pub.dev/packages/firebase_auth_mocks 目前不支持 FirebaseAuth.createUserWithEmailAndPassword 方法。
您可以通过像这样定义自己的 createUserWithEmailAndPassword 方法来解决这个问题：
Future<MockUserCredential> createUserWithEmailAndPassword({@required String email, @required String password}) async {
return MockUserCredential(false, tUser);
}
MockUserCredential 可以通过添加以下行来导入：
// ignore: implementation_imports
import 'package:firebase_auth_mocks/src/mock_user_credential.dart';
使用实现导入的原因是类没有随库一起导出。
并且您可以通过替换这一行来使用新创建的 createUserWithEmailAndPassword 方法：
var credential = await auth.createUserWithEmailAndPassword(
email: email, password: password);
这样：
var credential = await createUserWithEmailAndPassword(
email: email, password: password);
