How to directly open an android media folder path using this package?

Following is my flutter code to open media folder inside flutter. But it always redirect me to device path only after then I need to select folder manually like I need to go to "Android" then select "Media" folder to get acccess to it.

What is the way to direct get access to folder for "Android" > "Media"?

import 'package:flutter/material.dart';
import 'package:saf_util/saf_util.dart';

class MediaAccessRequestScreen extends StatefulWidget {
  @override
  _MediaAccessRequestScreenState createState() =>
      _MediaAccessRequestScreenState();
}

class _MediaAccessRequestScreenState extends State<MediaAccessRequestScreen> {
  final _safUtilPlugin = SafUtil();
  var _status = '';

  String makeUriString({String path = "", bool isTreeUri = false}) {
    String uri = "Android/media/";
    String base = "content://com.android.externalstorage.documents/tree/primary%3A";
    String documentUri = "/document/primary%3A${path.replaceAll("/", "%2F").replaceAll(" ", "%20")}";
    if (isTreeUri) {
      uri = base + path.replaceAll("/", "%2F").replaceAll(" ", "%20");
    } else {
      var pathSegments = path.split("/");
      var fileName = pathSegments[pathSegments.length - 1];
      var directory = path.split("/$fileName")[0];
      uri = base +
          directory.replaceAll("/", "%2F").replaceAll(" ", "%20") +
          documentUri;
    }
    return uri;
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('Saf example app')),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              ElevatedButton(
                  onPressed: () async {
                    try {
                      debugPrint("makeUriString: ${makeUriString()}");
                      final dir = await _safUtilPlugin.pickDirectory(
                          writePermission: true, initialUri: makeUriString());
                      if (dir == null) {
                        return;
                      }
                      if (!context.mounted) {
                        return;
                      }

                      debugPrint('path selected : ${dir.uri}, ${dir.name}');
                      setState(() {
                        _status = 'success: ${dir.uri}, ${dir.name}';
                      });
                    } catch (err) {
                      setState(() {
                        _status = 'Error: $err';
                      });
                    }
                  },
                  child: const Text('Hello')),
              SizedBox(height: 16),
              Text(_status)
            ],
          ),
        ),
      ),
    );
  }
}

Let me know what I'm missing?

Thanks
