currentDirectory property
override
    Creates a directory object pointing to the current working directory.
Implementation
@override
Directory get currentDirectory => directory(io.Directory.current.path);override
    Sets the current working directory to the specified path.
The new value set can be either a Directory or a String.
Relative paths will be resolved by the underlying file system implementation (meaning it is up to the underlying implementation to decide whether to support relative paths).
Implementation
@override
set currentDirectory(dynamic path) => io.Directory.current = path;
