deprecated_member_use

'{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 or class member is used in a different package.

If the method m in the class C is annotated with @deprecated, then the following code produces this diagnostic:

void f(C c) {
  c.m();
}

The documentation for declarations that are annotated with @deprecated should indicate what code to use in place of the deprecated code.

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.
