Android 11 Permission Issue

my flutter code is

 var storageInfo = await PathProviderEx.getStorageInfo();
    var root = storageInfo[0]
        .rootDir; 
    var fm = FileManager(root: Directory(root)); 
     await fm.filesTree(
        excludedPaths: [
          '/storage/emulated/0/Android',
        ],
        extensions: ['pdf']
        );

error occur

E/flutter (16591): FileSystemException: Directory listing failed, path = '/storage/emulated/0/Android/obb' (OS Error: Permission denied, errno = 13)
E/flutter (16591): #0      FileManager.dirsTree (package:flutter_file_manager/src/file_manager.dart:110:7)
E/flutter (16591): #1      FileManager.filesTree (package:flutter_file_manager/src/file_manager.dart:132:34)

I have one issue to get list of files from stroage in android 11 from Flutter app

i already add both permission in AndroidManifest.xml file

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Solution

  • We need to request manage_external_storage permission via permission_handler.

    Add this permission to AndroidManifest.xml

    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

    Request permission as shown below

    await Permission.manageExternalStorage.request();

    Then we can read any file and write to any location in Android 11.
