-## Migrating from `package:pedantic`
-
-In migrating from the predefined lint sets provided by the [`package:pedantic`],
-you get static analysis coverage from 29 additional lints. There are, however,
-6 lints which the pedantic package includes which are not included in the
-predefined lint sets provided by the lints package:
-`always_declare_return_types`, `prefer_single_quotes`,
-`sort_child_properties_last`, `unawaited_futures`, `unsafe_html`, and
-`use_full_hex_values_for_flutter_colors` (also included in
-[`package:flutter_lints`]). To keep any of these lints enabled,
-add them to your [analysis options][customizing static analysis].
-
-Additionally, `package:pedantic` provides the `unawaited` method for use with
-`unawaited_futures`. With SDK version 2.14 this method is available in the
-`dart:async` package, and this is now the recommended way to use it. Be sure to
-mark the minimum SDK version of your package as `2.14` if you do so.
