splitPath function

({String basename, String dir, String ext}) splitPath(String path)

Splits path into (directory, basename, extension).

splitPath('/foo/bar.txt') => ('/foo', 'bar', '.txt')

Implementation

({String dir, String basename, String ext}) splitPath(String path) {
  final normalized = normalizePath(path);
  final lastSlash = normalized.lastIndexOf('/');
  final dir = lastSlash == -1 ? '.' : normalized.substring(0, lastSlash);
  final file = lastSlash == -1
      ? normalized
      : normalized.substring(lastSlash + 1);
  final dotIdx = file.lastIndexOf('.');
  if (dotIdx <= 0) {
    return (dir: dir, basename: file, ext: '');
  }
  return (
    dir: dir,
    basename: file.substring(0, dotIdx),
    ext: file.substring(dotIdx),
  );
}
