如何获取当前小程序的sdk编译版本号？

使用原生app内嵌uniapp应用时，会将应用编译成wgt包，然后在app中显示出来。
这个时候有两个sdk的版本概念：

1. app自身的sdk有一个sdk的版本号，这个可以通过“plus.runtime”获取，如下所示，其中uniVersion就是原生app的sdk版本

   
   {  
   "appid": "HBuilder",  
   "arguments": "",  
   "version": "13.1.18",  
   "innerVersion": "1.9.9.80859",  
   "uniVersion": "3.1.18",  
   "launchLoadedTime": "414",  
   "launcher": "default",  
   "origin": "default",  
   "processId": 1700,  
   "startupTime": "1626255394554",  
   "restart": "function() { [native code] }",  
   "install": "function() { [native code] }",  
   "getProperty": "function() { [native code] }",  
   "quit": "function() { [native code] }",  
   "openURL": "function() { [native code] }",  
   "launchApplication": "function() { [native code] }",  
   "setBadgeNumber": "function() { [native code] }",  
   "openFile": "function() { [native code] }",  
   "isStreamValid": "function() { [native code] }",  
   "openWeb": "function() { [native code] }",  
   "isApplicationExist": "function() { [native code] }",  
   "processDirectPage": "function() { [native code] }",  
   "isCustomLaunchPath": "function() { [native code] }",  
   "updateInfo": "function() { [native code] }",  
   "getDCloudId": "function() { [native code] }",  
   "agreePrivacy": "function() { [native code] }",  
   "disagreePrivacy": "function() { [native code] }",  
   "isAgreePrivacy": "function() { [native code] }",  
   "downloadFile": "function() { [native code] }",  
   "versionCode": 130118,  
   "channel": ""  
   }  

问题：还有一个sdk是编译应用时使用的sdk版本号，这个版本号如何获取？
