resolveSymbolicLinks method
Resolves the path of a file system object relative to the current working directory.
Resolves all symbolic links on the path and resolves all .. and . path
segments.
resolveSymbolicLinks 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,
resolveSymbolicLinks 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 resolveSymbolicLinks. One way of doing this is with the Uri
class:
var path = Uri.parse('.').resolveUri(Uri.file(input)).toFilePath();
if (path == '') path = '.';
var resolved = await File(path).resolveSymbolicLinks();
print(resolved);
since Uri.resolve removes .. segments. This will result in the Windows
behavior.
On Windows, attempting to resolve a symbolic link where the link type does not match the type of the resolved file system object will cause the Future to complete with a PathAccessException error.
