00:04Let’s get to the design of our screen. In the build method, instead of the Placeholder, let’s return a Scaffold. In its appbar, let’s show a title with a Text widget containing the name of the list:

appBar: AppBar(title: Text(_listName)), 

body: FutureBuilder<List<FileSystemEntity>>( 
  future: _getFiles(), 
  builder:(context, snapshot) { 
  }, 
) 

if (snapshot.connectionState == ConnectionState.waiting) { 
  return const Center(child: CircularProgressIndicator()); 
} 

return Center(child: Text('Error: ${snapshot.error}')); 

final dateString = '${date.year}-${date.month}-${date.day}'; 

final size = file.lengthSync(); 

var subtitle = ''; 
if (_showSize) subtitle +=  'File size: ${size.toString()}'; 
if (_showDate) subtitle +=  'Last modified: $dateString'; 
return ListTile( 
  title: Text(file.path.split('/').last), 
  subtitle: Text(subTitle), 
  onTap: () {} 
);
