FileSystemEntity class abstract
The common superclass of File, Directory, and Link.
FileSystemEntity objects are returned from directory listing operations. To determine whether a FileSystemEntity is a File, a Directory, or a Link perform a type check:
if (entity is File) (entity as File).readAsStringSync();
You can also use the type or typeSync methods to determine the type of a file system object.
Most methods in this class exist both in synchronous and asynchronous versions, for example, exists and existsSync. Unless you have a specific reason for using the synchronous version of a method, prefer the asynchronous version to avoid blocking your program.
Here's the exists method in action:
var isThere = await entity.exists();
print(isThere ? 'exists' : 'nonexistent');
