Flutter使用Patrol运行自动化测试时遭遇远程连接拒绝错误求助

我在尝试用Patrol运行一个简单的自动化测试时遇到了连接拒绝的错误，具体报错内容如下：

Patrol (native): configure() failed: (GrpcError: configure() failed with code UNAVAILABLE (Error connecting: SocketException: The remote computer refused the network connection.

(OS Error: The remote computer refused the network connection

下面是我的测试代码：

import 'package:flutter/material.dart';
import 'package:flutter_myapp/main.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:patrol/patrol.dart';

void main() async {
  patrolTest("Login user successfully", (PatrolTester $) async {
    await $.pumpWidgetAndSettle(const MyApp());

    await $.native.enterText(
      Selector(textContains: 'Nombre'), text: "Juan Pablo");
    await $.native.enterText(
      Selector(textContains: 'Apellido'), text: "Gonzalez");

    await $.native.tap(Selector(textContains: 'Open second page'));

    expect($("Juan Pablo").waitUntilVisible(), findsOneWidget);
  }, nativeAutomation: true);
}

需要说明的是，我已经配置好了安卓设备，并且严格按照Patrol的官方设置步骤完成了配置，但还是遇到了这个问题，有没有大佬能帮忙解决一下？

这是我的pubspec.yaml文件内容：

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.

# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.
