/**
* Requests the user for the provided permissions.
* <p>
* This method will throw an error if it is called before all permission requests that were
* requested in a previous call have been resolved.
* <p>
* Android distinguishes between
* <a href="https://developer.android.com/guide/topics/permissions/overview#runtime">runtime permissions</a>
* and
* <a href="https://developer.android.com/guide/topics/permissions/overview#special">special permissions</a>.
* Runtime permissions give an app additional access to restricted data or let the app perform
* restricted actions that more substantially affect the system and other apps. These
* permissions present the user with a dialog where they can choose to grant or deny the
* permission. Special permissions guard access to system resources that are particularly
* sensitive or not directly related to user privacy. These permissions are requested by sending
* an {@link Intent} to the OS. The OS will open a special settings page where the user can
* grant the permission.
* Runtime permission request results will be reported through
* {@link this#onRequestPermissionsResult(int, String[], int[])}, while special permissions
* request results will be reported through {@link this#onActivityResult(int, int, Intent)}.
* When these methods receive request results, they check whether all permissions that were
* requested through this method were handled, and if so, return the result back to Dart.
*
* @param permissions the permissions that are requested.
* @param activity the activity.
* @param successCallback the callback for returning the permission results.
* @param errorCallback the callback to call in case of an error.
