canonicalizePath method Null safety

String canonicalizePath(
  1. String path
)

If the path path is a relative path, convert it to an absolute path by interpreting it relative to this folder. If it is already an absolute path, then don't change it.

However, regardless of whether path is relative or absolute, normalize it by removing path components of the form '.' or '..'.

Implementation

String canonicalizePath(String path);
