deprecated_member_use_from_same_package

'{0}' is deprecated and shouldn't be used.

'{0}' is deprecated and shouldn't be used. {1}

The analyzer produces this diagnostic when a deprecated library member or class member is used in the same package in which it's declared.

The following code produces this diagnostic because x is deprecated:

@deprecated
var x = 0;
var y = x;

The fix depends on what's been deprecated and what the replacement is. The documentation for deprecated declarations should indicate what code to use in place of the deprecated code.

Unless stated otherwise, the documentation on this site reflects Dart 3.7.3. Page last updated on 2025-05-08. View source or report an issue.
