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.
}
},
