Unity3d 如何检查项目中是否安装了软件包

我正在创建一个模块，用于在场景中查找文本字段。 如果安装了TextMeshPro，它将查找它，如果未安装，则查找常规textfield/text mesh

问题是：如何设置条件（伪代码）

您可以使用以编程方式与包管理器交互

浏览项目中的包列表：

using System;
using UnityEditor;
using UnityEditor.PackageManager.Requests;
using UnityEditor.PackageManager;
using UnityEngine;

namespace Unity.Editor.Example {
   static class ListPackageExample
   {
       static ListRequest Request;

       [MenuItem("Window/List Package Example")]
       static void List()
       {
           Request = Client.List();    // List packages installed for the Project
           EditorApplication.update += Progress;
       }

       static void Progress()
       {
           if (Request.IsCompleted)
           {
               if (Request.Status == StatusCode.Success)
                   foreach (var package in Request.Result)
                       Debug.Log("Package name: " + package.name);
               else if (Request.Status >= StatusCode.Failure)
                   Debug.Log(Request.Error.message);

               EditorApplication.update -= Progress;
           }
       }
   }
}

如果在标题上方有PackageName，该怎么办？

using System;
using UnityEditor;
using UnityEditor.PackageManager.Requests;
using UnityEditor.PackageManager;
using UnityEngine;

namespace Unity.Editor.Example {
   static class ListPackageExample
   {
       static ListRequest Request;

       [MenuItem("Window/List Package Example")]
       static void List()
       {
           Request = Client.List();    // List packages installed for the Project
           EditorApplication.update += Progress;
       }

       static void Progress()
       {
           if (Request.IsCompleted)
           {
               if (Request.Status == StatusCode.Success)
                   foreach (var package in Request.Result)
                       Debug.Log("Package name: " + package.name);
               else if (Request.Status >= StatusCode.Failure)
                   Debug.Log(Request.Error.message);

               EditorApplication.update -= Progress;
           }
       }
   }
}
