你可以使用android_package_manager，它使用android here和here的PackageManager API。你可以使用PackageInfo，它包含requestedPermissionshere。
Kotlin的例子类似于Flutter中的库。函数名称等几乎相同。

PackageManager pm = getPackageManager();
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo applicationInfo : packages) {
   Log.d("test", "App: " + applicationInfo.name + " Package: " + applicationInfo.packageName);

   try {
      PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName, PackageManager.GET_PERMISSIONS);

      //Get Permissions
      String[] requestedPermissions = packageInfo.requestedPermissions;

      if(requestedPermissions != null) {
         for (int i = 0; i < requestedPermissions.length; i++) {
            Log.d("test", requestedPermissions[i]);
         }
      }
   } catch (NameNotFoundException e) {
      e.printStackTrace();
   }
}
