FileManager class

FileManager is a wonderful widget that allows you to manage files and folders, pick files and folders, and do a lot more. Designed to feel like part of the Flutter framework.

Sample code

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