Resolves the path of a file system object relative to the
current working directory, resolving all symbolic links on
the path and resolving all .. and . path segments.
resolveSymbolicLinksSync uses the operating system's native
file system API to resolve the path, using the realpath function
on linux and OS X, and the GetFinalPathNameByHandle function on
Windows. If the path does not point to an existing file system object,
resolveSymbolicLinksSync throws a FileSystemException.
On Windows the .. segments are resolved before resolving the symbolic
link, and on other platforms the symbolic links are resolved to their
target before applying a .. that follows.
To ensure the same behavior on all platforms resolve .. segments before
calling resolveSymbolicLinksSync. One way of doing this is with the Uri
class:
var path = Uri.parse('.').resolveUri(new Uri.file(input)).toFilePath();
if (path == '') path = '.';
var resolved = new File(path).resolveSymbolicLinksSync();
print(resolved);
since Uri.resolve removes .. segments. This will result in the Windows
behavior.
