<manifest xmlns:android=""
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

You also need Runtime Request Permission allow storage permission from app setting manually or you may use any package such as permission_handler.

or use FileManager to request permission at runtime.

  // request permission
  await controller.requestFilesAccessPermission();


  await FileManager.requestFilesAccessPermission();

Basic setup

The complete example is available here.

Required parameter for FileManager are controller and builder

  • controller The controller updates value and notifies its listeners, and FileManager updates itself appropriately whenever the user modifies the path or changes the sort-type with an associated FileManagerController.
final FileManagerController controller = FileManagerController();
  • builder This function allows you to create custom widgets and retrieve a list of entities List<FileSystemEntity>.

Sample code

    controller: controller,
    builder: (context, snapshot) {
    final List<FileSystemEntity> entities = snapshot;
      return ListView.builder(
        itemCount: entities.length,
        itemBuilder: (context, index) {
          return Card(
            child: ListTile(
              leading: FileManager.isFile(entities[index])
                  ? Icon(Icons.feed_outlined)
                  : Icon(Icons.folder),
              title: Text(FileManager.basename(entities[index])),
              onTap: () {
                if (FileManager.isDirectory(entities[index])) {
                    controller.openDirectory(entities[index]);   // open directory
                  } else {
                      // Perform file-related tasks.
