undefined_hidden_name

The library '{0}' doesn't export a member with the hidden name '{1}'.

The analyzer produces this diagnostic when a hide combinator includes a name that isn't defined by the library being imported.

The following code produces this diagnostic because dart:math doesn't define the name String:

import 'dart:math' hide String, max;

var x = min(0, 1);

If a different name should be hidden, then correct the name. Otherwise, remove the name from the list:

import 'dart:math' hide max;

var x = min(0, 1);

Unless stated otherwise, the documentation on this site reflects Dart 3.8.0. Page last updated on 2025-05-08. View source or report an issue.
