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

filemanager(
    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.
                  }
              },
            ),
          );
