copySync method Null safety

File copySync (
  1. String newPath
)

Synchronously copies this file.

If newPath is a relative path, it is resolved against the current working directory (Directory.cwd).

Returns a File for the copied file.

If newPath identifies an existing file, that file is removed first. If newPath identifies an existing directory the operation fails and an exception is thrown.

Implementation

File copySync(String newPath);
