pathPrefix method

String pathPrefix([
  1. int relativePath = 0
])

Returns a string representation of the URI with a truncated path.

relativePath specifies how many segments from the end of the path should be excluded. For example, if the URI is https://example.com/a/b/c and relativePath is 1, the result will be https://example.com/a/b. Throws an Exception if the path segments are empty.

Implementation

String pathPrefix([int relativePath = 0]) {
  if (pathSegments.isEmpty) throw Exception("Path segments are empty");
  // Remove the last [relativePath] + 1 segments from the path.
  List<String> segments =
      pathSegments.sublist(0, pathSegments.length - 1 - relativePath);
  // Create a new URI with the truncated path and no query parameters.
  Uri newUri = replace(pathSegments: segments, queryParameters: {});
  // Return the string representation without the query part.
  return newUri.toString().replaceAll('?', '');
}
