Flutter get External Storage Directory and MediaStore with path_provider package - flutter

Question

I need to open and save simple text files that may be on the device. For example in Documents, Downloads, etc. Wherever files are available for other programs, in android terminology it is "External Storage"
path_provider provides several methods. One of them getExternalStorageDirectory(). The android documentation says:
This method was deprecated in API level 29. To improve user privacy,
direct access to shared/external storage devices is deprecated. When
an app targets Build.VERSION_CODES.Q link
If I use methods path_provider
getExternalStorageDirectory() → /storage/emulated/0/Android/data/myapp.name/files
getApplicationDocumentsDirectory() → /data/user/0/myapp.name/app_flutter
getExternalStorageDirectories(type: StorageDirectory.documents) return List which contains
/storage/emulated/0/Android/data/myapp.name/files/Documents
/storage/1CEE-4019/Android/data/myapp.name/files/Documents
On my android emulator (Api 30) real external documents are located at
/storage/emulated/0/Documents
/storage/emulated/0/Download
How can I access them? As I understand it, there are no alternatives forpath_provider
