+## Stricter than Effective Dart
+
+Here are the important places where `pedantic` is stricter than Effective Dart:
+
+`annotate_overrides` is stricter; Effective Dart says nothing about
+`@override`.
+
+`omit_local_variable_types` is stricter; Effective Dart only says to
+[avoid](https://dart.dev/guides/language/effective-dart/design#avoid-type-annotating-initialized-local-variables)
+type annotating initialized local variables.

+single vs double quotes.

+`use_function_type_syntax` is stricter; Effective Dart only says to

 ## Using the Lints
 
 To use the lints add a dependency in your `pubspec.yaml`:
